A co-simulation, optimization, control approach for traffic light control with truck priority

摘要

Under certain conditions giving priority to trucks at signalized intersections will benefit all vehicles because of elimination of extra delays associated with stop and go trucks due to their size and slow deceleration and acceleration rates. In this paper, we develop, analyse and evaluate a traffic light control system for signalized intersections that takes into account the differences in dynamics and characteristics between trucks and passenger vehicles. The proposed traffic light control system combines simulation-based optimization techniques timing the baseline traffic signals and model-based active strategy giving priority to trucks when it is to the benefit of all vehicles involved. In order to overcome the computational constraints of the simulation-based approach, a multiple agent-based solution utilizing multiple simulators has been proposed for large scale road network applications. The evaluation results show consistent improvements in reducing the truck traffic delays (5% to 10%) and the number of truck stops without delaying passenger vehicles whose travel time and number of stops have also been reduced. The reductions of vehicle delays and number of stops lead to reduction in emission levels and fuel consumption for both trucks and passenger vehicles. (C) 2019 Elsevier Ltd. All rights reserved.
