The Integrated Dial-a-Ride Problem

open access: yesPublic Transport, 2008
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. The IDARP is a generalization of the Dial-a-Ride Problem.

The Clustered Dial-a-Ride Problem

open access: yesProceedings of the International Conference on Automated Planning and Scheduling, 2019
We study a variant of the classical dial-a-ride problem, with an application to public transport planning in rural areas. In the classical dial-a-ride problem, n users each specify a pickup and a delivery location, and the aim is to plan the least cost route to cater all requests.

The electric autonomous dial-a-ride problem [PDF]

open access: yes, 2020
This thesis develops mathematical programming frameworks to operate electric autonomous vehicles in the context of ride-sharing services. The introduced problem is a novel variant of the Dial-a-Ride Problem (DARP), denoted by the electric Autonomous Dial-a-Ride Problem (e-ADARP), and includes battery management and autonomous aspects along with classic

The Electric Dial-a-Ride Problem on a Fixed Circuit

open access: yesTransportation Science, 2023
Shared mobility services involving electric autonomous shuttles have increasingly been implemented in recent years. Because of various restrictions, these services are currently offered on fixed circuits and operated with fixed schedules. This study introduces a service variant with flexible stopping patterns and schedules.
