Modeling travel time under the influence of on-street parking

On-street parking is an important component of the parking system. Because of its occupancy of roadway resources, it can significantly impact traffic performance and safety. The aim of this paper is to give a quantitative analysis of the influence of on-street parking on travel time. The travel time data of the motor vehicles moving in the road sections with on-street parking are gathered by observers. A proportional hazard-based duration model is proposed to analyze the influential factors related to on-street parking, including effective lane width, the number of parking maneuvers, and occupancy. The results show that on-street parking has a significant impact on the travel time of vehicles. In addition, various factors can modify travel time in different degrees, and the model can be used to estimate the travel time under assumed conditions. It is hoped that this paper will help to improve the planning and management of on-street parking.
