Abstract Urbanization elevates traffic congestion and it has a great impact on the smooth mobility of the citizens. To combat the traffic congestion problem, the concept of multimodal transportation can be used effectively which encourages the citizens to avail of different public transport or combination of public and private transport to reach their destination rather than using a dedicated personal car. Therefore, this paper introduces a multimodal transportation system that can be used as a prototype to implement the concept of multimode transport in smart cities. The proposed system has several components, out of which route recommendation service is proposed and discussed in detail. The route recommendation service guides the citizens to reach the destination smoothly and in a timely manner. For that, this paper proposes an optimal route finding algorithm for the multimodal environment based on the A* technique which suggests the best possible paths based on user preferences like link congestion, distance, or cost of travelling. A heuristic function is formulated in this work to speed up the process of finding the optimal route. The simulation results show that the proposed multimodal transportation system helps in reducing traffic congestion. © 2022, The Author(s), under exclusive licence to Shiraz University.
