Comprehensive Benefit Evaluation of Intersections Controlled by Signals Based on Stochastic Frontiers

Abstract

As an important part of urban road traffic system, signal-controlled intersection has become one of the hot spots in urban road traffic research due to its geographical location and complex operation state. Due to the current goals and means of the optimal design of intersections are not clear enough, the intersection has not played a full role, and eventually the traffic efficiency is not high, congestion not only does not decrease but increases, but also leads to a high proportion of traffic accidents, hindering social economic development. In order to establish an evaluation system for signal-controlled intersections, this paper proposes a comprehensive evaluation index of signal-controlled intersections with traffic efficiency, safety and environment, and establishes an evaluation method for signal-controlled intersections based on stochastic frontier analysis. Finally, an example is used to verify that the method is feasible.
