Abstract:With the development of city and the quality improvement of central urban area, there are the dead-end roads in the central urban area, which are particularly difficult to optimize and have many constraints. In recent years, it has attracted more and more attention from relevant functional departments and leaders. Through a comprehensive survey of the construction space of bottleneck areas of traffic, the factors restricting the development of transportation channels are analyzed and summarized. Under the target premise of improving the regional transportation efficiency, balancing the traffic flow within the road network and enhancing the transportation service functions, the traffic conditions are systematically analyzed, the interchange node schemes are optimized, and the actionability of the channel is strengthened, which provide the technical reference for the design of similar channel projects in the future.
