TLDR
A relocation algorithm for waiting cars based on virtual spring forces is proposed which is a key factor to improve utilization rate of the car sharing system and is reported on.Abstract:
Recently, Car Sharing System is focused as a new public transportation system in Japan. However, traditional car sharing systems which we call Pre-Reserve Car Sharing System require advance reservations, and the number of stations where users get on/off for the systems is small. Thus, the number of users is limited availability and most of users only apply the system to round driving. On the other hand, the advances of global positioning systems and communication techniques improve the system in a new and different way. We call the new system On-Demand Car Sharing System. In the new system, users are available for the system on demand, i.e., users can get on/off any time and any stations. Thus, users apply the system to one-way driving in addition to round driving. In this paper, we focus on location balances of cars which is a key factor to improve utilization rate of the system. We propose a relocation algorithm for waiting cars based on virtual spring forces. In the last of this paper, we report our simulation results and show the effectiveness of our algorithm.read more

Static repositioning in a bike-sharing system: models and solution approaches
TL;DR: This paper presents two mixed integer linear program formulations of a routing model that generalizes existing routing models in the literature and indicates that one of the formulations is very effective in obtaining high quality solutions to real life instances of the problem.

Relocation Strategies and Algorithms for Free-Floating Car Sharing Systems
Simone Weikl,Klaus Bogenberger +1 more
TL;DR: A new integrated two-step algorithm for optimal positioning and strategy selection is described in detail, which consists of an offline demand clustering that allows for strategy pre-selection and an online module that measures the differences between optimal vehicle positioning and current positioning and selects the best relocation strategy for implementation.

One-Way Carsharing: Solving the Relocation Problem
TL;DR: A user-based methodology was proposed on the basis of an optimal relocation policy in a rolling horizon framework that offers greater flexibility to users and maximizes operator benefits by reducing the number of required staff to relocate vehicles among the stations and determines the minimum number of vehicles needed to satisfy system demand.
