Abstract
Abstract. Create, maintain and development of public transport network in metropolitan are important problems in the field of urban transport management. In public transport, maximize the efficient use of public fleet capacity has been considered. Concepts and technologies of GIS have provided suitable way for management and optimization of the public transports systems. In demand-responsive public transportation system, firstly fellow traveller groups have been established for applicants based on spatial concepts and tools of GIS, second for each group according to its’ members and their paths, a public vehicle has been allocated to them then based on dynamic routing, the fellow passenger group has been gathered from their origins and has been moved to their destinations through optimal route. The suggested system has been implemented based on network data and commuting trips statistics of 1 to 6 districts in Tehran city. Evaluation performed on the results show the 34% increase using of Taxi capacity, 13% increase using of Van capacity and 10% increase using of Bus capacity in comparison between current public transport system and suggested public transportation system has been improved.
Highlights
Transportation systems generally involve issues related to land use, demographic information, economic and environmental data
GIS is an appropriate tool for data integration, because the spatial dimensions can be communicated between different systems
Statistics of commuting trips is used to simulate travel demands based on the land use of each area
Summary
Transportation systems generally involve issues related to land use, demographic information, economic and environmental data. Most information in transportation system is location reference data, i.e., the spatial dimensions. GIS is an appropriate tool for data integration, because the spatial dimensions can be communicated between different systems. The most important role of GIS is inserting spatial dimensions in transportation models. GIS-T focuses on analysis and planning in the application of GIS technologies for transportation issues. Urban transportation and traffic management systems are being developed using GIS and IT tools. Features such as traffic monitoring, traffic lights control, and the creation of new ITS areas have become possible using these technologies, which is an important step in the field of urban traffic management
