| Abstract | In this paper, taking traffic signal delay and link interaction into account, a bi-level system optimization traffic flow equilibrium assignment model is presented with the aim of minimizing total travel time of the network in first-level while ensuring equal saturation of each link in the second level. In the model, the link cost contains travel time between two intersections plus signal delay at the downstream intersection. To make the model easily and effectively be solved, the paper presents a quasi equilibrium assignment algorithm, in which the calculation of equilibrium link flows is integrated with measurement of congestion considering both link and intersection. The algorithm may not have enough ability to make the congested traffic flow become smooth immediately, but the dissemination of traffic guidance information (via broadcast or in-vehicle equipment) to divert oversaturated traffic volume under certain traffic demand at consecutive intervals. At the same time, the optimal traffic signal timing is designed to allow the persistent adjustment in response to traffic flow variations. Finally, a computational experiment is carried out on a small network and using realistic intersection delay functions in order to test the behavior of the model. |

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.
