Improving the Methodology of Adaptive Traffic Control at Pedestrian Crosswalks
- Department of Transport Technologies, Lviv Polytechnic National University, Lviv, Ukraine
The paper presents the results of an experimental study carried out at signalized intersections and pedestrian crosswalks in Lviv (Ukraine). The study covered intersections with different traffic conditions. Therefore, the intersections were classified into three types. It was found that the share of pedestrians who cross the road on the prohibitive traffic signal varies from 7% in the central areas to 13% near transport hubs. A methodology, which predicts the pedestrian behavior when they make decisions about crossing the roadway, is proposed. Recommendations were developed for choosing the optimal traffic light control modes. It was found that increasing the duration of the restrictive signal for pedestrians increases the probability of crossing the road during the restrictive signal of the traffic light. It emphasizes the need to adjust the duration of the traffic light cycle in areas with heavy pedestrian traffic.
Keywords: traffic flow, pedestrian flow, signalized pedestrian crosswalk, traffic light cycle duration, traffic delay
