Road traffic accidents are one of the most important problems being faced by modern urban areas. Most of the countries in present world have been witnessing such hazards due to increasing growth of vehicular traffic as a result of population explosion coupled with large-scale socio-economic activities. Rapid growth of motorized two and four wheelers, mixed traffic flow, inadequate infrastructural safety measures, lack of proper traffic safety and inadequate post-crash hazard management are the responsible reasons for the over increasing growth of road traffic accidents in South East Asian Countries. Most of the world megacities are located in the less motorized countries (LMC) and many more cities in these countries will grow to population of more than ten million in the next few decades. Present study area Kolkata was one of them. The present paper was concerned with the spatiotemporal variation of road traffic accident within Kolkata Police Jurisdiction. To find out the variation, the study dealt with the police station wise occurrence of fatal and non-fatal cases for the time span of 2007 to 2014. Police station wise degree of inequality had been measured by the Location Quotient. The obtained values of location quotient had been arranged in a temporal framework to show the spatiotemporal variation. By summing up the individual scores an aggregated index was calculated. An effort had also been taken to identify the possible factors of such variation incorporating the controlling measures which are being practiced by the Kolkata police and which can be adopted to reduce the rate of accident in the city.
