Abstract

Vehicular Ad hoc Networks (VANETs) have garnered a lot of interest due to their distinctive qualities, such as dynamic topology and predictable mobility. The development of VANETs in road transportation systems is receiving significant funding from both the academic community and the automobile industry. Taxi service has currently faced various issues such as security, privacy, efficiency, payment, and robbery in the transportation system which needs state-of-the-art technologies for its modeling and verification. Further, basic security requirements, driver’s authentication, and passenger’s on-journey protection and privacy are addressed by using this model. Passenger registration, taxi reservation, cancellation, payment, refund payment as well as taxi monitoring are considered in the model. Roadside units have been utilized to sense environmental data as well as by using non-deterministic finite automata (NFA) in terms of states and transitions, we put forth a model for an automatic system. Vienna development method-specification language (VDM-SL), has been utilized for formal specification, formal analysis, and formal model verification and validation via the VDM-SL toolbox.
