平面信控交叉口右轉(zhuǎn)車輛與過街行人交通沖突研究
[Abstract]:With the rapid development of social economy, people travel more and more frequently, urban roads play an important role in life, the operation of intersection reflects the operation efficiency of the whole road network. As an important node in urban road, signal-controlled road intersection is the main place of traffic conflict. The right-turn vehicle of the signal-controlled road intersection without the special phase of right-turn will produce more frequent traffic conflicts with pedestrians during the turning, which will lead to the acceleration, deceleration and parking of right-turn vehicles, resulting in delay of right-turn vehicles. At the same time, it will threaten the safety of pedestrians. In the process of right-turn vehicles crossing the street, some right-turn vehicles are eager to drive or lack the knowledge of traffic, so they will rob the pedestrians. Although this behavior reduces the delay of the right-turn vehicles, it increases the danger of pedestrians crossing the street. Aiming at this problem, the research contents of this paper are as follows: (1) the method of combining video observation with manual observation is used to analyze the traffic flow of right-turning vehicle crossing the street without the special phase of right-turn. In this paper, the probability model of the right turning vehicle when the pedestrian Poisson distribution is crossing the street is established. On the basis of this, a delay model of right-turning vehicles crossing the street crossing is established and verified without the special phase of right-turn. (2) based on the consideration of right-turn vehicle grabbing, the equal probability fraction of pedestrians crossing the street is established. When crossing the street, the delay model of the right-turn vehicle passing through the pedestrian flow at the intersection is optimized. (3) the safety psychological distance model of the pedestrian crossing through the right-turn lane is optimized. In this paper, the safety psychology of pedestrians crossing the street is analyzed, the conflict risk degree is described qualitatively by conflict energy, and the conflict risk degree at Changsha intersection is calculated.
