Usability of dial-a-ride systems
Proceedings of the fourth international joint conference on Autonomous agents and multiagent systems, 2005A 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 ...

Disruption Management for Dial-A-Ride Systems
IEEE Intelligent Transportation Systems Magazine, 2020Mobility on demand has been gaining more attention from the research community as a way to offer smart and efficient transportation services to people. Despite the advancements in vehicular technologies, vehicle breakdown (VB) remains one of the major contributors to the disruption of fleet operations, which may inflict large recovery costs and damage ...

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.

ERICA (European Research Into Consumer Affairs) is engaged in research into problems faced, notably by the underprivileged, in the countries of the European Economic Community (EEC). An early project investigated dial-a-ride systems for the transport of disabled people in six EEC countries.

A Matheuristic for the Dial-a-Ride Problem
2011The 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

The finite capacity dial-a-ride problem
Proceedings 39th Annual Symposium on Foundations of Computer Science (Cat. No.98CB36280), 2002We give the first non-trivial approximation algorithm for the Capacitated Dial-a-Ride problem: given a collection of objects located at points in a metric space, a specified destination point for each object, and a vehicle with a capacity of at most k objects, the goal is to compute a shortest tour for the vehicle in which all objects can be delivered ...

Although as originally conceived demand responsive transport (drt) systems offered a many-to-many capability with complex computerised control, more recent developments have offered simpler, manually controlled, systems. From the introduction of the first UK drt systems in 1972 it is possible to observe three broad categories of drt: first generation ...

Customers' satisfaction in a dial-a-ride problem
IEEE Intelligent Transportation Systems Magazine, 2009This paper presents a general model for a dial-a-ride problem and a Simulated Annealing approach to solve it focusing on the quality of service. The model includes several distinct cases of the real problems and an objective function that treats transportation costs and customer's inconveniences. The routes are clustered and scheduled in a separate way
