GIS and assessment of the performance of the transport system and security

MOHAMMED AL-ALI, TRANSPORT RESEARCH INSTITUTE, EDINBURGH NAPIER UNIVERSITY, UK

Purpose – The purpose of this research is to develop an analysis of a systematic approach to generate and utilise GIS capabilities and create layers of combined data bases in order to devise indicators to assess the performance of transport systems. The impacts of various policies on these systems is evaluated and compared.
Design/methodology/approach – Accident analysis tools were used to calculate rates and severities of accidents before-and-after the implementation of a scheme. Travel demand forecasting models investigated impacts on modal split, route choice and other decision choices.
Findings – The use of such tools can be further extended to investigate the impacts of proposed policies and the impacts of specific variables on the performance of the transport system more efficiently.
Originality/value – Most of the available analysis and modelling tools of transport systems investigate transport problems on a single dimension or a single data set.
