不同速度引导策略下信号交叉口减排效果研究
Study on Emission Reduction Effect under Different Speed Guidance Strategies at Signalized Intersection
Abstract
Since the new century,environmental issues are on the rise,and as all important source
of urban pollution,traffic pollution also has been more and more to the impact of signal control,vehicle start-stops and idle speed contribute on the high emissions and high energy consumption at the the continuous promotion of cooperative vehicle infrastructure system,speed guidance strategy Can provide reasonable speed
mendations to drivers for going through the intersection smoothly,taking advantage of
vehicles’spatial and temporal trajectories and corresponding signal timing parameters.
This study established a low emission oriented speed guidance model introducing fuzzy control and a speed guidance model considering the turning limit speed,based on traditional green wave speed guidance order to explore the strategy influence on emissions and
energy consumptions,microscopic traffic simulation software VISSIM and its secondary
development was used to realize simulation environment under the speed guidance strategy
and through the collected driving characteristic data and microscopic emission model
MOVES,energy consumption and emission could be the experimental results,
prehensive index of total weighted cost Was applied to evaluation the a case
study,the intersection at Lianhe Road crossing Changjiang Road in Dalian Was selected.
Comparing the emissions of different driving behaviors after receiving the green wave
guidance,the results show that acceleration behavior causes 50%more emissions and
deceleration behavior causes 30%less establishment of the fuzzy controlled speed guidance model is for the purpose of restricting the higher pared with
green wave one,traffic emissions and energy consumptions decrease by 3%---5%with the
low emission oriented s
