1The Qitai radio telescope显示文摘This study presents a general outline of the Qitai radio telescope(QTT)project.Qitai,the site of the telescope,is a county of Xinjiang Uygur Autonomous Region of China,located in the east Tianshan Mountains at an elevation of about 1800 m.The QTT is a fully steerable,Gregorian-type telescope with a standard parabolic main reflector of 110 m diameter.The QTT has adopted an umbrella support,homology-symmetric lightweight design.The main reflector is active so that the deformation caused by gravity can be corrected.The structural design aims to ultimately allow high-sensitivity observations from 150 MHz up to115 GHz.To satisfy the requirements for early scientific goals,the QTTwill be equipped with ultra-wideband receivers and large field-of-view multi-beam receivers.A multi-function signal-processing system based on RFSo C and GPU processor chips will be developed.These will enable the QTT to operate in pulsar,spectral line,continuum and Very Long Baseline Interferometer(VLBI)observing modes.Electromagnetic compatibility(EMC)and radio frequency interference(RFI)control techniques are adopted throughout the system design.The QTT will form a world-class observational platform for the detection of lowfrequency(nano Hertz)gravitational waves through pulsar timing array(PTA)techniques,pulsar surveys,the discovery of binary black-hole systems,and exploring dark matter and the origin of life in the universe.The QTT will also play an important role in improving the Chinese and international VLBI networks,allowing high-sensitivity and high-resolution observations of the nuclei of distant galaxies and gravitational lensing systems.Deep astrometric observations will also contribute to improving the accuracy of the celestial reference frame.Potentially,the QTT will be able to support future space activities such as planetary exploration in the solar system and to contribute to the search for extraterrestrial intelligence.Na Wang Qian Xu Jun Ma Zhiyong Liu Qi Liu Hailong Zhang Xin Pei Maozheng Chen Richard N.Manchester Kejia Lee Xingwu Zheng Hans J.Kärcher Wulin Zhao Hongwei Li Dongwei Li Martin Süss Matthias Reichert Zhongyi Zhu Congsi Wang Mingshuai Li Rui Li Ning Li Guljaina Kazezkhan Wenming Yan Gang Wu Lang Cui Ming Zhang Haitao Li 2023Science China(Physics,Mechanics & Astronomy)2023,66,8:14
2Responses of root growth of Alhagi sparsifolia Shap. (Fabaceae) to different simulated groundwater depths in the southern fringe of the Taklimakan Desert, China显示文摘Alhagi sparsifolia Shap. (Fabaceae) is a spiny, perennial herb. The species grows in the salinized, arid regions in North China. This study investigated the response characteristics of the root growth and the distribution of one-year-old A. sparsifolia seedlings to different groundwater depths in controlled plots. The ecological adaptability of the root systems of A. sparsifolia seedlings was examined using the artificial digging method. Results showed that: (1) A. sparsifolia seedlings adapted to an increase in groundwater depth mainly through increasing the penetration depth and growth rate of vertical roots. The vertical roots grew rapidly when soil moisture content reached 3%-9%, but slowly when soil moisture content was 13%-20%. The vertical roots stopped growing when soil moisture content reached 30% (the critical soil moisture point). (2) The morphological plasticity of roots is an important strategy used by A. sparsifolia seedlings to obtain water and adapt to dry soil conditions. When the groundwater table was shallow, horizontal roots quickly expanded and tillering increased in order to compete for light resources, whereas when the groundwater table was deeper, vertical roots developed quickly to exploit space in the deeper soil layers. (3) The decrease in groundwater depth was probably responsible for the root distribution in the shallow soil layers. Root biomass and surface area both decreased with soil depth. One strategy of A. sparsifolia seedlings in dealing with the increase in groundwater depth is to increase root biomass in the deep soil layers. The relationship between the root growth/distribution of A. sparsifolia and the depth of groundwater table can be used as guidance for harvesting A. sparsifolia biomass and managing water resources for forage grasses. It is also of ecological significance as it reveals how desert plants adapt to arid environments.FanJiang ZENG Cong SONG HaiFeng GUO Bo LIU WeiCheng LUO DongWei GUI Stefan ARNDT DaLi GUO 2013Journal of Arid Land2013,5,2:13
3Reaction environment self-modification on low-coordination Ni^(2+)octahedra atomic interface for superior electrocatalytic overall water splitting显示文摘Large scale synthesis of high-efficiency bifunctional electrocatalyst based on cost-effective and earth-abundant transition metal for overall water splitting in the alkaline environment is indispensable for renewable energy conversion.In this regard,meticulous design of active sites and probing their catalytic mechanism on both cathode and anode with different reaction environment at molecular-scale are vitally necessary.Herein,a coordination environment inheriting strategy is presented for designing low-coordination Ni^(2+)octahedra(L-Ni-8)atomic interface at a high concentration(4.6 at.%).Advanced spectroscopic techniques and theoretical calculations reveal that the self-matching electron delocalization and localization state at L-Ni-8 atomic interface enable an ideal reaction environment at both cathode and anode.To improve the efficiency of using the self-modification reaction environment at L-Ni-8,all of the structural features,including high atom economy,mass transfer,and electron transfer,are integrated together from atomic-scale to macro-scale.At high current density of 500 mA/cm2,the samples synthesized at gram-scale can deliver low hydrogen evolution reaction(HER)and oxygen evolution reaction(OER)overpotentials of 262 and 348 mV,respectively.Kaian Sun Lei Zhao Lingyou Zeng Shoujie Liu Houyu Zhu Yanpeng Li Zheng Chen Zewen Zhuang Zhaoling Li Zhi Liu Dongwei Cao Jinchong Zhao Yunqi Liu Yuan Pan Chen Chen 2020Nano Research2020,13,11:12
4Vegetation fractional coverage change in a typical oasis region in Tarim River Watershed based on remote sensing显示文摘Vegetation fractional coverage(VFC) is an important index to describe and evaluate the ecological system.The vegetation index is widely used to monitor vegetation coverage in the field of remote sensing(RS).In this paper,the author conducted a case study of the delta oasis of Weigan and Kuqa rivers,which is a typical saline area in the Tarim River Watershed.The current study was based on the TM/ETM+ images of 1989,2001,and 2006,and supported by Geographic Information System(GIS) spatial analysis,vegetation index,and dimidiate pixel model.In addition,VBSI(vegetation,bare soil and shadow indices) suitable for TM/ETM+ images,constructed with FCD(forest canopy density) model principle and put forward by ITTO(International Tropical Timber Organization),was used,and it was applied to estimate the VFC.The estimation accuracy was later proven to be up to 83.52%.Further,the study analyzed and appraised the changes in vegetation patterns and revealed a pattern of spatial change in the vegetation coverage of the study area by producing the map of VFC levels in the delta oasis.Forest,grassland,and farmland were the three main land-use types with high and extremely-high coverage,and they played an important role in maintaining the vegetation.The forest area determined the changes of the coverage area,whereas the other two land types affected the directions of change.Therefore,planting trees,protecting grasslands,reclaiming farmlands,and controlling unused lands should be included in a long-term program because of their importance in keeping regional vegetation coverage.Finally,the dynamic variation of VFC in the study area was evaluated according to the quantity and spatial distribution rendered by plant cover digital images to deeply analyze the reason behind the variation.Fei ZHANG Tashpolat TIYIP JianLi DING Mamat SAWUT Verner Carl JOHNSON NigaraTASHPOLAT DongWei GUI 2013Journal of Arid Land2013,5,1:12
5Spatial distribution of soil moisture,salinity and organic matter in Manas River watershed,Xinjiang,China显示文摘With the classical statistical and geostatistical methods,the study of the spatial distribution and its influence factors of soil water,salinity and organic matter was carried out for 0-70 cm soil layers in Manas River watershed.The results showed that the soil moisture data from all soil layers exhibited a normal distribution,with average values of 14.08%-21.55%.Geostatistical analysis revealed that the content of soil moisture had a moderate spatial autocorrelation with the ratios of nugget/sill ranging from 0.500 to 0.718,which implies that the spatial pattern of soil moisture is influenced by the combined effects of structural factors and random factors.Remarkable spatial distributions with stripped and mottled features were found for soil moisture in all different soil layers.The landform and crop planting had a relatively big influence on the spatial distribution of soil moisture;total soil salinity was high in east but low in west,and non-salinized soil and lightly salinized soil appeared at the northwest and southwest of the study area.Under the effect of reservoir leakage,the heavily salinized soils are widely distributed in the middle of the study area.The areas of the non-salinized and lightly salinized soils decreased gradually with soil depth increment,which is contrary to the case for saline soils that reached a maximum of 245.67 km2 at the layer of 50-70 cm.The types of soil salinization in Manas River watershed were classified into four classes:the sulfate,chloride-sulfate,sulfate-chloride and chloride.The sulfate salinized soil is most widely distributed in the surface layer.The areas of chloride-sulfate,sulfate-chloride,and chloride salinized soils increased gradually along with the increment of soil depth;the variation range of the average values of soil organic matter content was between 7.48%-11.33%.The ratios of nugget/sill reduced gradually from 0.698 to 0.299 with soil depth increment,which shows that the content of soil organic matter has a moderate spatial autocorrelation.The soil organic matter in all soil layers met normal distribution after logarithmic transformation.The spatial distribution patterns of soil organic matter and soil moisture were similar;the areas with high organic matter contents were mainly distributed in the south of the study area,with the lowest contents in the middle.Jilili ABUDUWAILI Yang TANG Mireban ABULIMITI DongWei LIU Long MA 2012Journal of Arid Land2012,4,4:9
6Iron-group electrocatalysts for ambient nitrogen reduction reaction in aqueous media显示文摘Electrochemical nitrogen reduction reaction(NRR)is considered as an alternative to the industrial Haber-Bosch process for NH3 production due to both low energy consumption and environment friendliness.However,the major problem of electrochemical NRR is the unsatisfied efficiency and selectivity of electrocatalyst.As one group of the cheapest and most abundant transition metals,iron-group(Fe,Co,Ni and Cu)electrocatalysts show promising potential on cost and performance advantages as ideal substitute for traditional noble-metal catalysts.In this minireview,we summarize recent advances of iron-group-based materials(including their oxides,hydroxides,nitrides,sulfides and phosphides,etc.)as non-noble metal electrocatalysts towards ambient N2-to-NH3 conversion in aqueous media.Strategies to boost NRR performances and perspectives for future developments are discussed to provide guidance for the field of NRR studies.Benyuan Ma Haitao Zhao Tingshuai Li Qian Liu Yongsong Luo Chengbo Li Siyu Lu Abdullah M.Asiri Dongwei Ma Xuping Sun 2021Nano Research2021,14,3:8

9Modeling and simulation of urea-water-solution droplet evaporation and thermolysis processes for SCR systems显示文摘A reliable mathematical model of urea-water-solution(UWS) droplet evaporation and thermolysis is developed.The well known Abramzon–Sirignano evaporation model is corrected by introducing an adjustment coefficient considering the different evaporation behaviors of UWS droplet at different ambient temperatures. A semidetailed kinetic scheme of urea thermolysis is developed based on Ebrahimian's work. Sequentially, the evaporation characteristics, decomposition efficiency of a single UWS droplet and deposit formation are simulated. As a result, the relation of evaporation time, relative velocity, exhaust temperature and droplet initial diameter is presented. Synchronously, it indicates that temperature is the decisive factor for urea thermolysis. Different temperatures result in different deposit components, and deposit yield is significantly influenced by temperature and decomposition time. The current work can provide guidance for designing urea injection strategy of SCR systems.Xubo Gan Dongwei Yao Feng Wu Jiawei Dai Lai Wei Xingwen Li 2016Chinese Journal of Chemical Engineering2016,24,8:7
10Design and manufacture AR head-mounted displays:A review and outlook显示文摘Augmented reality head-mounted displays(AR-HMDs)enable users to see real images of the outside world and visualize virtual information generated by a computer at any time and from any location,making them useful for various applications.The manufacture of AR-HMDs combines the fields of optical engineering,optical materials,optical coating,precision manufacturing,electronic science,computer science,physiology,ergonomics,etc.This paper primarily focuses on the optical engineering of AR-HMDs.Optical combiners and display devices are used to combine real-world and virtual-world objects that are visible to the human eye.In this review,existing AR-HMD optical solutions employed for optical combiners are divided into three categories:optical solutions based on macro-,micro-,and nanooptics.The physical principles,optical structure,performance parameters,and manufacturing process of different types of AR-HMD optical solutions are subsequently analyzed.Moreover,their advantages and disadvantages are investigated and evaluated.In addition,the bottlenecks and future development trends in the case of AR-HMD optical solutions are discussed.Dewen Cheng Qiwei Wang Yue Liu Hailong Chen Dongwei Ni Ximeng Wang Cheng Yao Qichao Hou Weihong Hou Gang Luo Yongtian Wang 2021Light(Advanced Manufacturing)2021,2,3:6
11Porous LaFeO3 nanofiber with oxygen vacancies as an efficient electrocatalyst for N2 conversion to NH3 under ambient conditions显示文摘Electrocatalytic N2 reduction to NH3 under ambient conditions is an eco-friendly and sustainable alternative to the traditional Haber-Bosch process. However, inhibited by the high activation barrier of N2, this process needs efficient electrocatalysts to adsorb and activate the N2, enabling the N2 reduction reaction(NRR). Herein, we report that porous LaFeO3 nanofiber with oxygen vacancies acts as an efficient NRR electrocatalyst with abundant active sites to enhance the adsorption and activation of N2. When tested in 0.1 M HCl, such electrocatalyst achieves a high Faradaic efficiency of 8.77% and a large NH3 yield rate of 18.59 μg h–1 mgcat–1.at-0.55 V versus reversible hydrogen electrode. This catalyst also shows high long-term electrochemical stability and excellent selectivity for NH3 formation. Density functional theory calculations reveal that, by introducing oxygen vacancy on LaFeO3, the subsurface metallic ions are exposed with newly localized electronic states near the Fermi level, which facilitates the adsorption and activation of N2 molecules as well as the subsequent hydrogenation reactions.Chengbo Li Dongwei Ma Shiyong Mou Yongsong Luo Benyuan Ma Siyu Lu Guanwei Cui Quan Li Qian Liu Xuping Sun 2020Journal of Energy Chemistry2020,29,11:6
12Development of a large-scale remote sensing ecological index in arid areas and its application in the Aral Sea Basin显示文摘The Aral Sea Basin in Central Asia is an important geographical environment unit in the center of Eurasia.It is of great significance to the ecological protection and sustainable development of Central Asia to carry out dynamic monitoring and effective evaluation of the eco-environmental quality of the Aral Sea Basin.In this study,the arid remote sensing ecological index(ARSEI)for large-scale arid areas was developed,which coupled the information of the greenness index,the salinity index,the humidity index,the heat index,and the land degradation index of arid areas.The ARSEI was used to monitor and evaluate the eco-environmental quality of the Aral Sea Basin from 2000 to 2019.The results show that the greenness index,the humidity index and the land degradation index had a positive impact on the quality of the ecological environment in the Aral Sea Basin,while the salinity index and the heat index exerted a negative impact on the quality of the ecological environment.The eco-environmental quality of the Aral Sea Basin demonstrated a trend of initial improvement,followed by deterioration,and finally further improvement.The spatial variation of these changes was significant.From 2000 to 2019,grassland and wasteland(saline alkali land and sandy land)in the central and western parts of the basin had the worst ecological environment quality.The areas with poor ecological environment quality are mainly distributed in rivers,wetlands,and cultivated land around lakes.During the period from 2000 to 2019,except for the surrounding areas of the Aral Sea,the ecological environment quality in other areas of the Aral Sea Basin has been improved in general.The correlation coefficients between the change in the eco-environmental quality and the heat index and between the change in the eco-environmental quality and the humidity index were–0.593 and 0.524,respectively.Climate conditions and human activities have led to different combinations of heat and humidity changes in the eco-environmental quality of the Aral Sea Basin.However,human activities had a greater impact.The ARSEI can quantitatively and intuitively reflect the scale and causes of large-scale and long-time period changes of the eco-environmental quality in arid areas;it is very suitable for the study of the eco-environmental quality in arid areas.WANG Jie LIU Dongwei MA Jiali CHENG Yingnan WANG Lixin 2021Journal of Arid Land2021,13,1:5
13Occurrence of human pathogenic bacteria carrying antibiotic resistance genes revealed by metagenomic approach: A case study from an aquatic environment显示文摘Antibiotic resistance genes(ARGs), human pathogenic bacteria(HPB), and HPB carrying ARGs are public issues that pose a high risk to aquatic environments and public health. Their diversity and abundance in water, intestine, and sediments of shrimp culture pond were investigated using metagenomic approach. A total of 19 classes of ARGs, 52 HPB species, and 7 species of HPB carrying ARGs were found. Additionally, 157, 104, and 86 subtypes of ARGs were detected in shrimp intestine, pond water, and sediment samples, respectively. In all the samples, multidrug resistance genes were the highest abundant class of ARGs. The dominant HPB was Enterococcus faecalis in shrimp intestine, Vibrio parahaemolyticus in sediments, and Mycobacterium yongonense in water, respectively. Moreover, E. faecalis(contig Intestine_364647)and Enterococcus faecium(contig Intestine_80272) carrying efr A, efr B and ANT(6)-Ia were found in shrimp intestine, Desulfosaricina cetonica(contig Sediment_825143) and Escherichia coli(contig Sediment_188430) carrying mex B and APH(3′)-IIa were found in sediments, and Laribacter hongkongensis(contig Water_478168 and Water_369477), Shigella sonnei(contig Water_880246),and Acinetobacter baumannii(contig Water_525520) carrying sul1, sul2, ere A, qac H, OXA-21, and mph D were found in pond water. Mobile genetic elements(MGEs) analysis indicated that horizontal gene transfer(HGT) of integrons, insertion sequences, and plasmids existed in shrimp intestine, sediment, and water samples, and the abundance of integrons was higher than that of other two MGEs. The results suggested that HPB carrying ARGs potentially existed in aquatic environments, and that these contributed to the environment and public health risk evaluation.Renjun Zhou Shenzheng Zeng Dongwei Hou Jian Liu Shaoping Weng Jianguo He Zhijian Huang 2019Journal of Environmental Sciences2019,31,6:5

15Root characteristics of Alhagi sparsifolia seedlings in response to water supplement in an arid region,northwestern China显示文摘The effect of variation in water supply on woody seedling growth in arid environments remain poorly known.The subshrub Alhagi sparsifolia Shap.(Leguminosae),distributed in the southern fringe of the Taklimakan Desert,Xinjiang,northwestern China,has evolved deep roots and is exclusively dependent on groundwater,and performs a crucial role for the local ecological safety.In the Cele oasis,we studied the responses of A.sparsifolia seedling roots to water supplement at 10 and 14 weeks under three irrigation treatments(none water supply of 0 m3/m2(NW),middle water supply of 0.1 m3/m2(MW),and high water supply of 0.2 m3/m2(HW)).The results showed that the variations of soil water content(SWC) significantly influenced the root growth of A.sparsifolia seedlings.The leaf area,basal diameter and crown diameter were significantly higher in the HW treatment than in the other treatments.The biomass,root surface area(RSA),root depth and relative growth rate(RGR) of A.sparsifolia roots were all significantly higher in the NW treatment than in the HW and MW treatments at 10 weeks.However,these root parameters were significantly lower in the NW treatment than in the other treatments at 14 weeks.When SWC continued to decline as the experiment went on(until less than 8% gravimetric SWC),the seedlings still showed drought tolerance through morphological and physiological responses,but root growth suffered serious water stress compared to better water supply treatments.According to our study,keeping a minimum gravimetric SWC of 8% might be important for the growth and establishment of A.sparsifolia during the early growth stage.These results will not only enrich our knowledge of the responses of woody seedlings to various water availabilities,but also provide a new insight to successfully establish and manage A.sparsifolia in arid environments,further supporting the sustainable development of oases.DongWei GUI FanJiang ZENG Zhen LIU Bo ZHANG 2013Journal of Arid Land2013,5,4:5

17A new Euprox from the Late Miocene of Yuanmou, Yunnan Province, China, with interpretation of its paleoenvironment显示文摘The Yuanmou Basin of Yunnan Province is ahotspot for the research of early hominid evolution and its environmental background. During the implementation ofthe Program 揜esearch of the Origin and Evolution of Early Man and Its Environmental Background?from 1998 to 2001, a huge quantity of hominoid and mammal fossils were col-lected. The present report systematically describes an Eu-prox robustus sp. nov. identified during the recent laboratory work on the collected material. Euprox is a group of earliest cervids with true antlers. The new species is the third one of the genus discovered in China. Judged by its morphologiccharacteristics, the new species feed on juicy and tenderleaves of dicotyledon. It implies that the vegetation of itsepoch in the Yuanmou Basin is a kind of southern subtropi-cal evergreen forest and the climate is humid and temperate with evident seasonality. The latter is mostly influenced by the monsoon and secondly by the latitude.DONGWei LIUJianhui PANYuerong 2003Chinese Science Bulletin2003,48,5:4
18Cognitive-behavioural therapy for personal recovery of patients with schizophrenia:A systematic review and meta-analysis显示文摘Background To date, cognitive-behavioural therapy (CBT) trials have primarily focused on clinical recovery;however, personal recovery is actually the fundamental aspect of the recovery process. The aim of this study was to summarise and synthesise the existing evidence regarding the effectiveness of CBT for personal recovery In patients with schizophrenia. Aim This study aimed to determine the effectiveness of CBT for personal recovery in patients with schizophrenia. Methods A systematic search of the literature in PsycINFO, PubMed, Cochrane (CENTRAL), Embase and Web of Science (SCI) was conducted to identify randomised controlled trials reporting the impact of CBT interventions on personal recovery in patients with schizophrenia. The estimated effect sizes of the main study outcomes were calculated to estimate the magnitude of the treatment effects of CBT on personal recovery. We also evaluated the CBT’s effect size at the end-of-treatment and long-term (follow-up) changes in some aspects of personal recovery. Results Twenty-five studies were included in the analysis. The effect of CBT on personal recovery was 2.27 (95% CI 0.10 to 4.45;I^2=0%;p=0.04) at post-treatment and the long-term effect size was 2.62 (95% CI 0.51 to 4.47;I^2=0%;p=0.02). During the post-treatment period, the pooled effect size of CBT was 0.01 (95% CI -0.12 to 0.15;I^2=33.0%;p>0.05) for quality of life (QoL), 0.643 (95% CI 0.056 to 1.130;I^2=30.8%;p<0.01) for psychological health-related QoL,-1.77 (95% CI -3.29 to -0.25;I^2=40%;p=0.02) for hopelessness and 1.85 (95% CI 0.69 to 3.01;I^2=41%;p<0.01) for self-esteem. We also summarised the effects of CBT on QoL (subscale scores not included in the evaluation of the pooled effect size), self-confidence and connectedness, and all results corresponded to positive effects. However, there was insufficient evidence regarding the long-term effects of CBT on personal recovery. Conclusions CBT is an effective therapy with meaningful clinical effect sizes on personal recovery and some aspects of personal recovery of schizophrenia after treatment. However, the effect is relatively immediate and rapidly decreases as time progresses. Therefore, in the future, more studies should focus on the mechanism of CBT for personal recovery and the factors that influence the long-term effects of CBT.Weiliang Wang Yuqiu Zhou Nannan Chai Dongwei Liu 2019General Psychiatry2019,32,4:4
19Enhancing electrocatalytic N_(2)-to-NH_(3) fixation by suppressing hydrogen evolution with alkylthiols modified Fe_(3)P nanoarrays显示文摘Electrocatalytic N_(2) reduction provides an attractive alternative to Haber-Bosch process for artificial NH_(3) synthesis.The difficulty of suppressing competing proton reduction,however,largely impedes its practical use.Herein,we design a hydrophobic octadecanethiol-modified Fe_(3)P nanoarrays supported on carbon paper(C18@Fe_(3)P/CP)to effectively repel water,concentrate N_(2),and enhance N_(2)-to-NH_(3) conversion.Such catalyst achieves an NH_(3) yield of 1.80×10^(-10) mol s^(-1)·cm^(-2) and a high Faradaic efficiency of 11.22%in 0.1 M Na_(2)SO_(4),outperforming the non-modified Fe_(3)P/CP(2.16×10^(-11) mol s^(-1)·cm^(-2),0.9%)counterpart.Significantly,C18@Fe_(3)P/CP renders steady Nrfixing activlty/selectivity in cycling test and exhibits durability for at least 25 h.First-principles calculations suggest that the surface electronic structure and chemical activity of Fe_(3)P can be well tuned by the thiol modification,which facilitates N_(2) electroreduction activity and catalytic formation of NH_(3).Tong Xu Jie Liang Yuanyuan Wang Shaoxiong Li Zhaobai Du Tingshuai Li Qian Liu Yonglan Luo Fang Zhang Xifeng Shi Bo Tang Qingquan Kong Abdullah M.Asiri Chun Yang Dongwei Ma Xuping Sun 2022Nano Research2022,15,2:4
20Virtual speed sensors based algorithm for expressway traffic state estimation显示文摘The accurate estimation of expressway traffic state can provide decision-making for both travelers and traffic managers. The speed is one of the most representative parameter of the traffic state. So the expressway speed spatial distribution can be taken as the expressway traffic state equivalent. In this paper, an algorithm based on virtual speed sensors (VSS) is presented to estimate the expressway traffic state (the speed spatial distribution). To gain the spatial distribution of expressway traffic state, virtual speed sensors are defined between adjacent traffic flow sensors. Then, the speed data extracted from traffic flow sensors in time series are mapped to space series to design virtual speed sensors. Then the speed of virtual speed sensors can be calculated with the weight matrix which is related with the speed of virtual speed sensors and the speed data extracted from traffic flow sensors and the speed data extracted from traffic flow sensors in time series. Finally, the expressway traffic state (the speed spatial distribution) can be gained. The acquisition of average travel speed of the expressway is taken for application of this traffic state estimation algorithm. One typical expressway in Beijing is adopted for the experiment analysis. The results prove that this traffic state estimation approach based on VSS is feasible and can achieve a high accuracy.XU DongWei DONG HongHui JIA LiMin QIN Yong 2012Science China(Technological Sciences)2012,55,5:4
