PROJECT TITLE :
Collective Travel Planning in Spatial Networks
Travel coming up with and recommendation are important aspects of transportation. We have a tendency to propose and investigate a novel Collective Travel Planning (CTP) query that finds very cheap-price route connecting multiple sources and a destination, via at most meeting points. When multiple travelers target the same destination (e.g., a stadium or a theater), they'll wish to assemble at meeting points and then go along to the destination by public transport to reduce their international travel cost (e.g., energy, money, or greenhouse-gas emissions). This kind of functionality holds the potential to bring important benefits to society and therefore the environment, like reducing energy consumption and greenhouse-gas emissions, enabling smarter and greener transportation, and reducing traffic congestions. The CTP query is Max SNP-onerous. To compute the query efficiently, we tend to develop 2 algorithms, as well as an precise algorithm and an approximation algorithm. The exact algorithm is capable finding the optimal result for small values of (e.g., ) in interactive time, while the approximation algorithm, which has a -approximation ratio, is appropriate for different things. The performance of the CTP query is studied experimentally with real and artificial spatial information.
