Identification and Prioritization of accident black-spots in Kerala State IDENTIFICATION AND PRIORITIZATION OF ACCIDENT BLACK SPOTS IN KERALA The accident-prone spots, according to road type, obtained as hard copy from IG Traffic on 05.11.2016 was analyzed based on the MoRTH definition of Black spots and prioritized based on District-wise Accident Severity Index (ASI) value. Definition of Black spot (MoRTH): According to Ministry of Road Transport & Highways (MoRTH), Government of India, road accident black spot on National Highways is a road stretch of about 500m in length in which either 5 road accidents (involving fatalities/grievous injuries) took place during last three calendar years or 10 fatalities took place during last three calendar years. According to National Highway Authority of India (NHAI), hazardous locations are evaluated based on Accidents Severity index (ASI). Hazardous spots with Accidents Severity Index (ASI) more than Threshold value (Average Severity + 1.5*Standard Deviation) will be treated as Black spots. For estimation of ASI, the weightage to fatal accident will be assigned as 7 and to grievous injury accident as 3, was considered based on NHAI's criteria. The threshold value computation formula for first order, second order, third order, fourth and fifth order priority black spots are given in Table 1. Table 1: Threshold value of priority black spots Priority Threshold value First order black spots Average Severity + 1.5*Standard Deviation Second order black spots Average Severity + Standard Deviation Third order black spots Average Severity + 0.5*Standard Deviation Fourth order black spots Average Severity Fifth order black spots Below Average Severity A total of 355 black spots have been identified in Kerala based on MoRTH's definition and prioritized based on district-wise ASI value. Of 355 black spots, 200 Black spots are on National Highways, 110 black spots are on State Highways and 45 black spots are on Other roads. In case of Ernakulam district, the list of 1st order, 2nd order and 3rd order black spots identified as part of scientific study "Identification and Prioritization of Accident Black spots in Ernakulam district" conducted by NATPAC National Transportation Planning and Research Centre 1 Identification and Prioritization of accident black-spots in Kerala State has been incorporated in the list.
