Modeling and Optimizing Dynamic Dial-a-Ride Problems

International Transactions in Operational Research, 2001
Dial‐a‐ride is an emerging alternative to traditional public transportation systems. The aim of this paper is to reduce the gap between the models studied in optimization literature and the requirements of practical applications. We also describe the algorithms implemented in DARIA, a PC program for the optimization of static and dynamic dial‐a‐ride ...

A New Formulation for the Dial-a-Ride Problem

Transportation Science, 2021
This paper proposes a new mixed integer programming formulation and branch and cut (BC) algorithm to solve the dial-a-ride problem (DARP). The DARP is a route-planning problem where several vehicles must serve a set of customers, each of which has a pickup and delivery location, and includes time window and ride time constraints.

Usability of dial-a-ride systems

Proceedings of the fourth international joint conference on Autonomous agents and multiagent systems, 2005
A case study of usability of dial-a-ride bus systems is reported. We conduct a social simulation to compare efficiencies of the dial-a-ride bus systems, one of possible multi-agent applications, and traditional fixed-route bus systems. Simulation results indicated that dial-a-ride systems are reasonable for large cities but their advantage depends on ...

A Matheuristic for the Dial-a-Ride Problem

2011
The Dial-a-Ride is a transport system on demand. A fleet of vehicles, without fixed routes and schedules, carries people from their pickup points to their delivery points, during a pre-specified time interval. It can be modeled as an N P-hard routing and scheduling problem, with a suitable mixed integer programming formulation. Exact approaches to this

DIAL‐A‐RIDE

Journal of Consumer Studies & Home Economics, 1983
One of the worst things about being disabled is the loneliness. Able‐bodied people do not have to wait for busy friends to find time to visit them. They can get on to a bus or a tube or a train and go visiting, or to the shops or a cinema or club, as the mood takes them. If you are in a wheelchair, you can't.
