A significant percentage of pedestrians walk in social groups (friends, families, or acquaintances who together). Although patterns generated by interactions among group members have been shown to affect crowd dynamics, studies on the effect at different crossing phases under low pedestrian density are limited. This study aims comprehensively examine influence size and sex composition pedestria...

With the development of economic, the traffic requirement rapidly increases in Shanghai. Besides building more new infrastructures, the administrators put forward to many countermeasures to increase the vehicle traffic capacity previously and to meet the traffic requirement in China. At the same time, the urban traffic facilities are set up by different departments of government during differen...

Autonomous vehicles have gained popularity in recent years, but they are still not compatible with other vulnerable components of the traffic system, including pedestrians, bicyclists, motorcyclists, and occupants smaller such as passenger cars. This incompatibility leads to reduced system performance undermines safety comfort. To address this issue, authors considered pedestrian crosswalks whe...

Both humans and the sensors on an autonomous vehicle have limited sensing capabilities. When these limitations coincide with scenarios involving vulnerable road users, it becomes important to account for these limitations in the motion planner. For the scenario of an occluded pedestrian crosswalk, the speed of the approaching vehicle should be a function of the amount of uncertainty on the road...

Cellular automata modeling techniques and the characteristics of mixed traffic flow were used to derive the 2-dimensional model presented here for simulation of pedestrian's crossing dynamics. A conception of "stop point" is introduced to deal with traffic obstacles and resolve conflicts among pedestrians or between pedestrians and the other vehicles on the crosswalk. The model can be easily ex...

To create a crosswalk that predicts Short Form 6D (SF-6D) utilities from Memorial Anxiety Scale for Prostate Cancer (MAX-PC) scores. The data come prostate cancer patients enrolled in the North Carolina Comparative Effectiveness & Survivorship Study (NC ProCESS, N = 1016). Cross-sectional 12- to 24-month follow-up were used as estimation and validation datasets, respectively. Participants’ SF-1...

This study compares, on a simulator, drivers' performance (eye fixations and yielding behavior) at marked mid-block crosswalks in multi-threat scenarios when the crosswalks have advance yield markings and pedestrian crosswalk prompt signs versus their performance in such scenarios when the crosswalks have standard markings. Advance yield markings and prompt signs in multi-threat scenarios lead ...
