Network design problem is one of the most complicated and yet challenging problems in transportation planning. The Bi-level, non-convex and integer nature of network design problem has made it into one of the most complicated optimization problems. Inclusion of time dimension to the classical network design problem could add to this complexity. In this paper an Ant Colony System (ACS) has been ...

The objective of the paper is to discuss the development of an alternative representation of the transportation network using object-oriented GIS. This representation is important for the supply side of transportation planning and modeling. Object-orientation provides a way of solving the problem in a planar network for routing. It can facilitate the calculation of detailed network characterist...

Fundamental to intermodal development is consistent demand modeling across the intermodal system, which coordinates resource allocation. However, different planning organizations are responsible for the development of different components of the intermodal system. In the case of air transportation, air demand modeling is mainly conducted by Federal Aviation Administration and commercial airline...

Intelligent transportation system (ITS) applied in the city traffic is mainly reflected in the microscopic traffic information collection, traffic control and guidance, to improve the efficiency of traffic system. Wireless sensor network has excellent characteristics, and it can provide an effective means for information collection of intelligent transportation system and can monitor the inters...

The stability of a user equilibrium determines whether it could be realized or sustained in a transportation network, when subject to perturbations in traffic conditions and drivers’ route choice behaviors. In this paper, with a simple deterministic dynamical system model of the traffic assignment problem, we first develop a systematic approach to analyzing asymptotic stability and instability ...

Today the concept of smart cities is discussed in scientific society and politics. A core function of smart cities is transportation. This paper gives a short overview on the concepts for Intelligent Transport Systems (ITS) for smart cities and proposes a framework for the design of an autonomic transportation system that provides personalized mobility services to its users in a smart city sett...

This paper addresses the debate regarding the respective merits of high and low fidelity prototypes, in the domain of video prototyping. Video prototyping is a popular tool for interface designers. Despite this, there is practically no research reported to date examining the fidelity of the design representation that the video prototype should manifest. We report a case study where the same des...
