Analyses & Evaluation Traffic Safety ,Management and ITS in crashes (Case Study: Shiraz)

The aim of this paper is to present and apply a new evaluation framework for traffic management and intelligent transport systems, to assist urban transport authorities in assessing relevant policies and technologies as to their performance. The principles behind performance measures and indices are outlined, along with a description of the framework development methodology. Two key performance indicators (KPIs) for the mobility and traffic accident respectively are formulated. Then, the new KPIs are applied to a case study in Shiraz, involving the introduction of a scheme granting priority to buses at signalized junctions. The results from the before-and after-analysis are reported and interpreted. It will be seen from the standpoint of the applicability of the evaluation framework.
