Analysis of the impact of vehicle flow on highway traffic in urban planning
Urban planning plays a leading role in urban development,coordination of traffic planning and overall planning of resources,and is also the action program and basis for road traffic construction.Traffic flow affects the choice of road grade,design speed and service function in traffic planning.Both urban planning and traffic flow have an important impact on traffic planning.This paper takes the traffic planning of Baoshan District in Shanghai as an example to analyze how urban planning and traffic flow affect traffic planning.The results show that the influence of urban planning on transportation planning is mainly reflected in the selection of aboveground,underground,starting point,ending point and passing area in space,and the selection of construction sequence and batch in time.Traffic flow affects the selection of road grade,service level,speed and lane in traffic planning.Only by accurately predicting traffic flow can we scientifically select the road location,road grade and lane number in traffic planning.
