| Abstract | This study investigates a method of predicting traffic flow that employs the use of abductive networks based on the group method data handling (GMDH) for short-term traffic flow prediction. The GMDH algorithm relies on high-order polynomial input variables and it starts by building regression equations of order 2 or 3 for each pair of input variables. The new input variables are used for predicting the output in lieu of the original input variables. Based on pre-specified selection criteria, the best new input variables (polynomials) in terms of predicting the output are retained and used as input variables for the next layer to generate newer input variables of higher order (order of 4 if started with order 2). This process continues until the added value of the predicting power becomes insignificant and/or the model becomes practically complex for predicting purposes. Models for a linear road network were developed first using both spatial and temporal information without differentiating between weekdays and weekends. In the subsequent efforts, different models were built for weekdays and weekends. It was found that day-specific mode performance is not better than the generic model in predicting traffic flow. Models developed for predicting traffic after 15 min had correlation coefficients between 0.97 and 0.98. Models which were developed to predict traffic after 30 min were also robust but with slightly lower values of correlation coefficient. Due to the self-organizing nature of the models and the minimum required interventions, the models can be easily used by practitioners. |

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.
