The Integrated Dial-a-Ride Problem
Public 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
Proceedings 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.

Revenue Maximization in Online Dial-A-Ride. [PDF]
, 2017 We study a variation of the Online-Dial-a-Ride Problem where each request comes with not only a source, destination and release time, but also has an associated revenue. The server's goal is to maximize its total revenue within a given time limit, T. We show that the competitive ratio is unbounded for any deterministic online algorithm for the problem.

Bilevel large neighborhood search for the electric autonomous dial-a-ride problem
Transportation Research Interdisciplinary Perspectives, 2023 The electric autonomous dial-a-ride problem (E-ADARP) represents a challenging and practically relevant extension of the dial-a-ride problem, which takes electric vehicle charging into account. It introduces battery constraints and the option to recharge
