One of the risks recognized by relevant authorities is the risk of outsourcing ITS projects. The purpose of this study was to design and explain the pattern of determining the critical success factors in outsourcing large-scale ITS projects in the Ministry of Roads and Urban Development (Road Maintenance and Transportation Organization). This study was performed using qualitative method. The pa...

Modeling traffic patterns has remained a difficult problem recently made even more complex by transportation modelers’ attempts to incorporate aspects of human decision making in traffic demand forecast methodology. In this paper, we propose to study the traffic pattern as the emerging result of the interplay between the urban/physical environment, the institutional context, the transportation ...

The concept of accessibility needs to take into account factors like individual needs, preferences, and abilities as well as transportation, land use, and finances. This article proposes a sensitive space–time accessibility indicator from a regional perspective. This indicator, representing cumulative available activity time with a regional context, is different from both traditional accessibil...

The transformation process towards sustainable road transportation implicitly requires that household’s car choice is not only influenced by individual or household specific objectives but also by societal objectives such as mitigating climate change. Hence the car purchase decision is seen as a citizen choice process, also including societal and ecological aspects in the decision function. The...

This study describes a system for the automatic recording of positioning data for public transport vehicles used on roads. With the data provided by this system, transportation-regulatory authorities can control, verify and improve the routes that vehicles use, while also providing new data to improve the representation of the transportation network and providing new services in the context of ...

An analysis pattern is any part of a requirement analysis specification that can be reused in the design of other information systems as well. Urban management systems (e.g.: Tax Control Systems, Urban Transportation System) are implemented in a similar way for many counties. This paper proposes three analysis patterns that make possible the reuse of geographic database design for urban area pl...

Abstract: We provide in this conceptual paper an overview of a parallel transportation / land use modeling environment. We argue that sequential urban modeling does not well represent complex urban dynamics. Instead, we suggest a parallel distributed processing structure composed of processors and links between processors. Each processor is a set of neurons and weights between neurons forming a...

Tactile sensor systems are an essential prerequisite for the implementation of complex manipulation and exploration tasks using robots. Tactile exploration has not yet found its way into many laboratories, because most tactile sensors are technically demanding and expensive. The desire to perform real-time control and pattern recognition with tactile sensors led us to the design of a cost-effec...

In this paper some research questions which potentially lie within the purview of the new discipline of Computational Transportation Science are presented. Some of these questions are no doubt old and jaded and some may rightly reside in a different research field (or be seen as engineering) but viable solutions to all of the issues presented are of vital importance to the efficacy of future tr...

We show how to route on very large public transportation networks (up to half a billion arcs) with average query times of a few milliseconds. We take into account many realistic features like: traffic days, walking between stations, queries between geographic locations instead of a source and a target station, and multi-criteria cost functions. Our algorithm is based on two key observations: (1...
