| 3 | Study of pedestrian hybrid beacon's effectiveness for motorists at midblock pedestrian crossings显示文摘Pedestrian signals,particularly at signalized,midblock crossings,delay drivers,which is termed 'unnecessary delay' in this study.A pedestrian hybrid beacon was proven to be effective in decreasing this unnecessary delay to the drivers at midblock pedestrian crossings when compared to standard signalized midblock crossings.Two pedestrian hybrid beacons were installed at midblock pedestrian crossings in Lawrence,Kansas.A study was conducted at these two locations to determine the effectiveness of the pedestrian hybrid beacon in decreasing the unnecessary delay to drivers by comparing them with a signalized midblock on Massachusetts Street,Lawrence,Kansas.In addition to the delay measurements for drivers at pedestrian hybrid beacon and signalized treatment at midblock pedestrian crossings,other parameters such as driver compliance rate,pedestrian compliance rate,and other driver and pedestrian characteristics were also studied.Video cameras were used at these test locations and the effectiveness of the pedestrian hybrid beacon was analyzed from the video.A more than 90%reduction in delays was observed for the drivers at the pedestrian hybrid beacon at midblock crossings compared to the signalized crossing.Further,a better driver compliance rate was also recorded at the pedestrian hybrid beacon.Information about reductions in unnecessary delay to drivers and improvements to driver and pedestrian compliance rates from the use of pedestrian hybrid beacons would be useful to engineers,decision makers,and researchers to determine an optimum treatment at desired pedestrian crossings. | Ranjit Prasad Godavarthy Eugene R.Russell | 2016 | Journal of Traffic and Transportation Engineering(English Edition)2016，3，6： | 0 |
