• A two-stage stochastic model is proposed for the design of carsharing systems with uncertainty demand. Sample average approximation used to find solutions in acceptable computation time. Sensitivity analysis identifies main drivers vehicle substitution. The can be as decision support tool system design. Carsharing has become a viable alternative mode transportation which not only contributes ...

Tracking vehicles can be the result of the requirement to keep track of a fleet or even simply to keep track of personal vehicle. In modern time where vehicle thefts are common, a GPS vehicle tracking system can come in helpful almost everywhere. This is a fast growing service enabling field where contribution is done from the side of various national and international service providers. This p...

In this paper we study the effect of vehiclevehicle/vehicle-roadside communication on the performance of adaptive cruise control (ACC) systems. Two simulation works are presented. One is a single ACC vehicle simulation using MATLAB/SIMULINK. A cut-in scenario and a braking scenario are tested. Communication greatly saves control effort in the former scenario, while has little effect in the latt...

For a number of years vehicle fleet tracking systems are in use in companies operating large number of vehicles in the field. Proliferation of cheap and compact GPS receivers had the effect that Automatic Vehicle Location (AVL) systems today almost exclusively use satellite based locating systems. This paper presents characteristics of realized system tracking and analyzing city bus transit tra...
