Shortest path and fastest path query on time-dependent road network are widely used nowadays, but none of them can answer a least on-road travel time query, which aims to find a path between two vertices on a time-dependent road network that has the minimum on-road travel time(waiting on any vertex is allowed). In this paper, we propose a cheapest path algorithm which expands Dijkstra’s Algorithm to solve this problem. The time complexity of it is \(O(|V|\log |V|+|V|T+|E|T^2)\), where T is the number of the involving time unit, |V| is the number of vertices and |E| is the number of edges. Extensive experiments are conducted on the two different speed profiles to test the performance of our cheapest path algorithm. The results validate the effectiveness of our work.
