| Abstract | As the important part of interchange, weaving area is the accident-prone and bottleneck of urban expressway because of a lot of weaving operations, where the traffic flow is needed to be intervened in order to improve the safety and efficiency. This paper divides traffic intervention measures into three kinds: driver behavior intervention, road condition intervention and traffic flow intervention, and studies the relationship between traffic flow intervention and traffic safety, efficiency under different demand. Conflict rate, traffic flow rate, delay per vehicle of weaving section and ramp are selected as the indices to analyze traffic safety and efficiency under three common intervention measures respectively, i.e. yield sign, speed limit and ramp metering. Finally, taking an example for Youyi Avenue interchange of Wuhan Yangtze River Tunnel, it analyzes how the traffic safety and efficiency changes under the condition of certain design property and different interventions in weaving area, and confirms the intervention measure in different traffic demand. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
