摘要

Jaywalking is a behavior that exposes the pedestrian to a high-risk condition and induces delay for vehicular traffic. The focus of most pedestrian research has been on the issue of safety. The goal of this research is to measure the impact on travel time and delay for vehicle traffic due to pedestrians who are crossing traffic, including jaywalkers. By using a micro-simulation software, VISSIM, the differences in travel time and delay time have been measured for a series of pedestrian scenarios. Data was collected in Newark, DE along East Main Street, a section of roadway serving many attractions near to the University of Delaware. Vehicle and pedestrian volumes and pedestrian crossing locations were observed and recorded during the midday peak hour.;Four scenarios were created in order to compare the effect of pedestrians and jaywalkers. This first scenario was titled the Base Case scenario and contained just the vehicle volumes and the signal timings for the main intersections. The Case 1 scenario introduced pedestrians at only the signalized crosswalks, which were located at each major intersection. Next, the Case 2 scenario contained the marked midblock crossings in addition to the already existing signalized crosswalks from Case 1. Finally, the Case 3 scenario contained jaywalkers, where pedestrians were free to cross wherever and whenever they appeared in the data collection. This scenario had several paths along East Main Street to allow pedestrians to cross freely with the right of way, in order to simulate jaywalking. In each case, pedestrian volumes were balanced to ensure the same total number of pedestrians were crossing.;The results showed that when pedestrians are legally crossing at the signalized locations, they do not obstruct traffic. However, when pedestrians are allowed to cross at the marked midblock crossings, there is a significant increase in travel time and delay when compared to a network with no pedestrians. This was also true when comparing the Base Case to the one with pedestrians and jaywalkers scattered throughout. Finally, we compared the jaywalking network to the network with pedestrians crossing legally at crosswalks and discovered that the addition of jaywalkers does have a significant impact on the travel time and delay of oncoming motorists.
