“…Therefore, it becomes important to know which PRT pods to move and where to move them with respect to the many constraints on the PRT system. This problem is called the empty vehicle redistribution (EVR) problem [26,27]. This paper is concerned with the empty vehicle redistribution problem for a PRT system that uses vehicles with limited battery capacity in both its static and dynamic versions.…”

The Personal Rapid Transit is a new emergent transportation tool. It relies on using a set of small driverless electric vehicles to transport people on demand. Because of the specific on-demand characteristic of the Personal Rapid Transit system, many Personal Rapid Transit vehicles would move empty which results in a high level of wasted transportation capacity. This is enhanced while using Personal Rapid Transit vehicles with limited electric battery capacity. This paper deals with this problem in a real time context while minimizing the set of empty vehicle movements. First, a mathematical formulation to benchmark waiting time of passengers in Personal Rapid Transit systems is proposed. Then, a simulation model that captures the main features of the Personal Rapid Transit system is developed. A decision support system which integrates several real time solution strategies as well as a simulation module is proposed. Our dispatching strategies are evaluated and compared based on our simulation model. The efficiency of our method is tested through extensive test studies.

“…A literature review published in 2005 [9] states that there is more than 200 research papers related to ATN. More recently, several operational and strategic optimization studies related to ATN were published such as network design [25], station design [24], dynamic routing [4][13], simulation [14], [7] energy minimization [22], passengers waiting time [20] total traveled distance [12][15], eet size [5], optimized operational planning [6][11] and so on. Starting from all these features, one could note that the transportation service for ATN consists on pickup passengers from a predened station in order to deliver them to another station.…”

“…However and in the literature, routing problems related to ATN considered only the single depot network topology with dierent objective such as energy minimization [12], eet size [5], waiting time of passengers [20] and so on. Consequently and based on all these features and this gap in the literature, we could state that routing driverless electric vehicles in the ATN'network has a strong relation with the multi depot one-to-one PDP with distance constraints.…”

Part 5: Industrial Management and Other ApplicationsInternational audienceThis paper presents the development of the multi depot one-to-one pickup and delivery problem with distance constraints problem. This problem involve routing vehicles in a multi depot network topology to satisfy a set of pickup and delivery requests subject to a maximum allowable distance constraint. A problem definition is given and a real world application is proposed for that problem. An approximate solution approach which divides the problem into several subproblems and solve them to optimality is also proposed. Computational experiments show that the proposed solution approach reach good quality solutions is a reasonable computational time

“…Unfortunately, the transportation literature related to PRT is at early stages. Special focus was put on the feasibility of PRT system and only recently there were focus on strategic and operational issues related to PRT [2]; [3]. This paper focuses on a specic related problem to the strategic level of decisions.…”

Abstract. In this paper, we address the problem of determining the optimal eet size for Personal Rapid Transit system(PRT). In our problem, we consider electric battery and distance constraints which are found in real world application of the PRT system. To tackle this problem, we propose two valid mathematical formulations that are able to nd optimal eet size. Extensive computational experiments show that the edge based formulation performs impressively well, in terms of solution quality and computational time in comparison to the node based formulation.
