A Study on the Confirmation of Pedestrians to Approaching Right/Left Turning Vehicle while Crossing the Crosswalk

摘要

In this study head-turning behavior is analyzed to understand where is the best location for thepedestrian to confirm the approaching vehicle in crossing the crosswalk. From the result of thehead-turning frequency, it is found that head-turning frequency is increasing towards the entryof the crosswalk and the conflict point. Moreover, results by the analysis of different attributes,head-turning frequency at nighttime or of the elderly person tends to be low; and head-turningwas performed more at the conflict point. These results might show that there is a need toprovide the information about approaching vehicle. In the pattern that vehicle approachesbehind the research participants, head-turning frequency is low; and this imply the need ofinformation for the pedestrians. By the result of the comparison with the different experimentsettings, it is found that the position where pedestrian just enter the crosswalk is the bestlocation to confirm the approaching vehicle in the 3 kinds of cases, such as elderly person(having difficulty in crossing), nighttime (restricted visibility), wearing headphones (restrictedhearing sense). Moreover, many head-turning behavior were performed at the middle ofcrosswalk in the case that start position of research participant is R and right-turning vehicle isapproaching, and this could be an appropriate confirming action. From the result describedabove, there exist many important locations for the crossing pedestrian to confirm theapproaching vehicle in a safe manner.
