A Simulation Analysis of Waiting Area for Through Vehicle Considering Emission Reduction
摘要
Abstract
Considering increasing congestion at intersections and air pollution in urban areas,this paper proposes a method of setting up a waiting area for through vehicles in front of through and right-turn sharing lane on the basis of e-mission reduction.This paper uses Vissim to study the sharing lane with waiting area for through vehicles.A control group without waiting area for through vehicles is setup for comparison.Parameters including link flows and right-turn ratio are changed systematically to evaluate their influences on a set of factors,including emissions,fuel consumption, average car delays and the number of stops.Weights are assigned to those factors to quantitatively evaluate the effective-ness of the lane configurations in terms of efficiency and environmental protection.This study finally develops an evalua-tion and optimization strategy with the consideration of energy conservation and emission reduction for through and right-turn sharing lane with waiting area for through vehicles.This paper also takes a signalized intersection of Jiangsu Road and Changning Road of Shanghai as a case study to illustrate the effectiveness of this strategy.Simulation results demon-strate that when the link flow is between 300~550 pcu/h and the right-turn ratio is between 40%~50%,it is the opti-mal point to set waiting areas for through vehicles.Under this condition,the through put efficiency improves by 22.9%;the automotive emission decreasesby 32.8%;and the fuel consumption decreases by 32%;the average car delays declines by 46%;and the number of stops increases by 43.7%.The benefit of setting waiting areas according to the proposed strat-egy is obvious,and the overall operating conditions at the signalized intersections can be greatly improved.关键词
