DES modeling of DRT. Edition No. 1
VDM Publishing House, April 2009, Pages: 120
Demand responsive transportation is a variable route
service of passengers or freight from specific origin
(s) to destination(s) in response to the request of
users. Recent methods for DRT planning and control
are based on closed information loop and aim a
higher level of service automation, flexibility and
efficiency. Advances in the information and
communication technologies, such as the Internet,
mobile communication devices, GIS, GPS, Intelligent
Transportation Systems have led to a significantly
complex and highly dynamical decision making
environment. In this study DRT systems are modeled
as Discrete Event Systems using Finite Automata
formalism and DRT real time control is addressed
using Supervisory Control Theory. Two application
scenarios are considered; the first is based on air-
charter service and the second one is a mission
critical application based on emergency evacuation
problem. The discussed methods should be
particularly useful to students and professionals in
Informatics and Transportation science field or
anyone who may deal in real time transportation
planning and control.
