| Abstract | A key process for urban transportation planning, the traffic assignment problem (TAP) determines the route choice of travelers and the flow of a traffic network. Under the user equilibrium (UE) condition, the travel costs of the chosen routes are identical for each origin-destination pair. The resulting UE flow bears significant resemblance to an electronic circuit. In particular, if the electrical current is viewed as the traffic volume, the voltage drop can be thought of as the travel time. Based on the fundamental idea “let electrons simulate travelers,” this study develops a TAP solution algorithm that iteratively solves the associated sub-problems based on electronic circuit simulation. Numerical experiments are performed to illustrate the key techniques used in developing the solution algorithm and to compare the performance with the classic Frank-Wolfe Algorithm. The solution approach based on circuit simulation is found to be a promising alternative to determine the UE flow of the TAP, and it has been used as the core algorithm of a prototype microprocessor system. |

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.
