“Identification and Improvements of Blackspots on a Stretch of SH-57 between Hassan and Holenarasipura”- A Case Study.

Abstract

In recent days humans prefer comfort in every form. The same cause has provoked him to lay the roads and
invent motor vehicles. In recent decades we are seeing very huge number of vehicles on the roads. But to his
disappointment, with this comfortless, there came the problem of accidents due to increase in traffic volume. The
increased human misery and serious economic loss caused by road accidents demand the attention of the society and call
for the solution of this problem. The causes for accidents are many. It may be either due to the fault of the driver or
vehicular defect, tough weather condition or due to improper road design and many more. Precisely, if accidents occur
frequently at a particular road stretch then, the location is coined as Black Spot. In the present work, an attempt has
been made to identify these Blackspots and to suggest the possible counter measures to prevent road accidents on SH57
between Hassan and Holenarasipura, Karnataka, India. The mixed traffic condition prevailing on the road and the
inadequate geometric conditions on field create the problem of increased accident rates. The Statistical study is made to
identify accident Blackspots by distribution of accidents to chainage, accident density, accident frequency and severity.
Improvement of Blackspots is made by ranking of accidents based on Accident point weightage, condition of blackspot
before improvement and after improvements are presented in drawing format.
