In an increasingly fast-paced world, emerging mobility demands must be met by competitive services that are in line with the principles of sustainable transportation concepts. It is not possible to know exactly what the mobility solution of the future will be, but it is certain that it will require a reduction in car use. A dramatic increase in energy prices will have an impact on the transportation sector, but making public transportation attractive to large numbers of people could reduce unit costs. Public transportation systems can be made more efficient through flexible transportation concepts and by combining individual passenger demand for travel. In the field of rail passenger transportation, practice uses fixed timetables, which do not take into account the changes in ad hoc travel needs. This results in significant losses due to unjustified unnecessary stops and longer travel times. This article presents an operational concept that enables ad hoc passenger demands to be met. The concept ensures minimum energy consumption and a higher level of passenger demand satisfaction through multilevel demand management. A case study was presented to prove the developed theory.

In metro cities, the effective and efficient management of traffic is one of the most demanding and time taking tasks. Vehicular ad hoc networks (VANET) provide unfailing, low-cost solutions for transportation systems with intelligence. VANET, a subclass of mobile ad hoc networks (MANET), allows exchange of information among vehicles and/or roadside devices. VANET can be implemented in numerous application areas such as effective traffic management, safety, and user comfort for drivers as well as passengers. It provides phenomenal growth to both in industries and research communities. Secure mobility and handoff management are the most promising and challenging research issues in VANET. In this paper, we have introduced the security in intra domain mobility handoff in PMIPv6 for VANET. Existing intra handover schemes does not include the authentication cost while evaluating the total packet delivery cost for intra domain handoff. Our proposed scheme includes the authentication cost of an intra-domain handover for evaluating the total packet delivery cost of handover for next-generation mobility management protocols, which is PMIPv6 for the vehicular network. We have considered the vital parameters such as the number of MAGs, setup cost, binding update cost, unit transmission cost for analyzing the total packet delivery cost. Furthermore, a comparative study with authentication and without authentication cost for the considered parameters shows that our proposed scheme secures the handover process with slight variation in cost.
