Improved Approximations for Dial-a-Ride Problems
CoRRThe multi-vehicle dial-a-ride problem (mDaRP) is a fundamental vehicle routing problem with pickups and deliveries, widely applicable in ride-sharing, economics, and transportation. Given a set of $n$ locations, $h$ vehicles of identical capacity $λ$ located at various depots, and $m$ ride requests each defined by a source and a destination, the goal ...

Dynamic Intercity Ride‐Sharing Optimisation Based on Two‐Stage Information Feedback
IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.The article introduces a novel two‐stage scheduling approach for intercity dynamic ridesharing that separates the process into a coarse scheduling phase (with online and offline vehicle matching) and a fine scheduling phase that refines the solution using a large neighbourhood search algorithm. By integrating deep Q‐learning to dynamically trigger fine

Integrating dial-a-ride services and public transport
, 2018 Dial-a-ride systems provide demand-responsive, collective transport to people with reduced mobility, such as elderly or disabled. Modern mobility policies also rely on these services to replace traditional public transport in rural areas, such that a ...

A modeling system for simulation of dial-a-ride services [PDF]
, 2012 We present a modeling system for simulation of dial-a-ride services. It can be used as a tool for understanding and study how different designs, and different ways to operate a dial-a-ride service, affect the performance and efficiency of the service ...

The Integrated Dial-a-Ride Problem
, 2009 In this paper we present a formulation of the Integrated Dial-a-Ride (IDARP). This problem is to schedule dial-a-ride requests, where some part of each journey may be carried out by a fixed route service.
