Time Dynamic Characteristics for Road Crashes in Developing Countries

Transportation encompasses a broad set of policy variables, and the planning and development of transportation facilities generally raises living standards and enhances the aggregate of community values. For the efficient planning of infrastructure and the constituent facilities, road traffic accidents has its own significance and demanding validity. Outputs from the system include the movement of people and traffic modes, improvement and deterioration of the physical environment as well. In contrast to all these factors, crash prevention is indirectly linked with the time of the occurrence or related incident. This corresponds to the spatial organization, circulation, visual properties, resources and symbolic properties.This paper focuses on road traffic accidents of Karachi, Pakistan involving various types of road users in different timings of the day (24 hrs). Possible root causes with significant recommended measures is the extensive dimension of this research study. Deliberate number of crash implications perceived by the application of ANOVA (Analysis of Variance) in the comparative analysis of three years data record. It is quite evident from the analytical data record that rate of severity is directly linked with the increase in insufficient illumination during dusk and dark timings. The positive progressive impact of time on traffic accidents is probably one of the important dimensions that will control the magnitude of the casualties.
