| Abstract | This paper proposes a nonlinear approach for designing traffic-responsive ramp controls using a genetic fuzzy approach. The problem is formulated as a nonlinear feedback control problem. To overcome the conventional problems of the calibration process of fuzzy controllers and improve the overall performance of ramp metering, an adaptive genetic-based algorithm is integrated into the system to periodically tune the fuzzy sets parameters. The approach thus adapts the control system automatically to changing traffic patterns. The objective of the ramp control is to minimize the total time spent in the freeway system while maintaining acceptable ramp service levels. Traffic data from a ramp study site in the Munich Autobahn (A9 motorway) was used to assess the genetic fuzzy controller using a hydrodynamic traffic model to estimate the genetic fitness. The paper concludes that adaptive fuzzy control based on genetic algorithms is expected to enhance the performance of ramp metering without compromising the cost-effectiveness associated with fuzzy controllers. |

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.
