| With the rapid development of cities and the rapid increase of motor vehicles, urbantraffic congestion is becoming increasingly serious.New or widen the road within the city toease urban traffic contradictions, has put forward the severe test of the urban land. Theadvanced traffic management tools to improve the urban road network capacity has becomethe focus of attention. One-way traffic is playing an important role in China’s urban trafficmanagement gradually, at the same time, triggered a series worthy of our inquiry andreflection problems in the implementation process, and the implementation of one-way trafficfeasibility is one of them. Our cities have a long history and are different with thecharacteristics of developed foreign urban road network, and how the Chinese chessboardtype road network in large area to implement one-way traffic is worth studying, and has veryimportant significance to alleviate the city traffic congestionThepaper considers the main features of the checkerboard road network are many andcomplex on the basis of summing up the advantages and disadvantages of one-way trafficconditions based on general conditions, and analyzes of the impact of one-way traffic to theroad node from the node complexity, signal control, capacity, delay and turning in five areas.By the combination of design from a holistic analysis of regional nodes, explore the impact ofthe regional transport efficiency. Learning from the successful experience of foreign countriesand combined with the evolution of China’s urban reminding, proposesuitable for China’snational conditions a wide range of conditions and principles for the implementation ofone-way traffic.Thepaper explores the conditions of the one-way traffic organization in the checkerboardroad network within the large-scale implementation and establishes the regional transportationefficiency evaluation model based on signal control with one-way traffic. In this process,analyzed the impact of the one-way traffic on the road node, trying to learn from thesuccessful experience of foreign countries, combined with China’s urban characteristics,explore the feasibility of our the checkerboard road network implementation of effective wayto alleviate urban traffic congestion. |
