Evaluation of motorized two-wheeler rider responses towards jaywalking pedestrians through mockup control studies for urban streets

This study aims to model the motorized two-wheeler (MTW) riders’ evasive-action behavior towards jaywalking pedestrians using a mockup study. The brake reaction times (BRTs), approach speeds, decelerations, headings, and yaw rates were analyzed for two surprise scenarios (scenarios 1 3), one stationary scenario (scenario-2), expected (scenario-4). In total, 50 riders participated in results revealed that 90th percentile BRT 3.6 1.6 s, respectively. Further, repeated-measures ANOVA was performed followed by mixed effect modeling ascertain of conflict severity (two groups: group-1 with Time Collision (TTC) < 1.5 s group-2 TTC > s) type (three 1, 3 4) on BRT. indicated main effects significant while interaction not significant. positive coefficient (0.32) higher BRTs than group-1. Considering scenario-1 as base scenario, (-0.02) scenario-3 had similar BRT, scenario-4 (1.47) compared scenario-1. analysis evasive action 32% hard braking scenarios. rate values at crossing point loss control MTW 90% events. observations from this provide basis developing countermeasures improve pedestrian rider safety.
