Teeradaj Racharak, Su yee Mon, Rathachai Chawuthai, Answer Set Programming for Bus Route Finding: A Case Study in Bangkok, Thailand, Proceedings of the 23rd International Joint Conference on Computer Science and Software Engineering (JCSSE 2026), June 24–27, 2026.

This paper presents an Answer Set Programming (ASP)-based approach to bus route finding in Bangkok, Thailand. The study models bus routes and stations as a directed graph and formulates route finding as a constraint-based planning problem that can reflect different user preferences, such as minimizing travel time and reducing the number of transfers. The proposed modular ASP encoding generates multiple high-quality route candidates and offers greater flexibility across different optimization criteria compared with conventional shortest-path approaches such as Dijkstra’s algorithm. The empirical study using real-world bus network data demonstrates the potential of ASP for flexible and preference-aware public transportation route planning.

Congratulations to the authors on this achievement!
