INTRODUCTION

Road accidents has turned as the biggest killer in northeast

Tripura fueled by reckless driving, less no. of traffic police

circulation across the state.

Amidst Road safety week’s celebration in January month

2017, atleast 25 people were killed in Tripura in last in

December to January.

Primary Vehicle and Secondary Vehicle(s) / Person(s) involved in the

road crash coupled with causative factors for the road crashes in the

entire state, the summary of the road crash data available in the

Ministry of Road Transport and Highways (MoRT&H) website was used

to understand the road crash patterns in Tripura for the years 2008 to

2015.

compared to some of the north eastern states

However, the deaths per 100 road crashes has registered minor increasing

trends which is a cause of concern warranting immediate intervention

measures.

ROAD CRASH DATA ANALYSIS FOR THE PROJECT CORRIDOR

First Information Reports (FIRs) related to detailed information for the

Project Corridor in terms of the number of road crashes, fatalities and

injuries i.e. Grievous and Simple Injury type crashes occurred on the

Project Corridor has been furnished by the PWD officials

Using the above road crash data, black spot analysis has been done by

the CSIR - CRRI team.

Yearly Trend in the Road Accidents

Total Accidents

From Figure it can be inferred that the number of road

crashes has registered fluctuating trends since the year 2012

till 2016 on the Project Corridor.

Therefore, it is not possible to draw definite inference from

the above.

Road Crash data collected from the records of the Tripura Police were analyzed

based on the type of vehicles involved namely, primary and secondary

vehicles/victims responsible for the road crashes

SYNOPSIS OF CRASH VICTIMS

The analysis also revealed that the Vulnerable Road Users (VRUs)

dominated by pedestrians (43.0 %), are the worst affected victims

constituting 36 %, which is followed by two wheelers (15.0 %) and bicycle

riders (6 %).

Attributed to absence of any form of facilities for the VRUs on the Project

Corridor.

In the case of pedestrians it may be due to the absence of the pedestrian

facilities such as Foot Over Bridges (FOBs) or Foot paths which is forcing

them to resort to crossing maneuver through jay walking by the alighting

commuters from buses and IPT to cross the road

In the case of motorized two wheelers, it may be attributed to the absence

of exclusive lanes for their movement.

WEIGHTED ACCIDENT SEVERITY INDEX

The intensity and seriousness of the accident

The ASI is computed by accounting 70 % weightage to the fatal crashes and

30 % to the Injury crashes.

ASI was higher in the year 2012, reduced until 2015

After 2015, increasing trends which is a cause of concern.

Proper engineering and education interventions can make this trend go

down significantly

CONT..

In the study site, pedestrians being the primary cause of

accident was found out to be negligible because of study

site passes through mostly inter-urban areas whereas in

the state, they have a certain amount of contribution may

be because of lack of FOBs and side walk facilties.

INFERENCE

The deaths per 100 road crashes has registered minor increase trend in the

state of Tripura as well as increasing trend in ASI after 2015

Around one fourth (23%) of the accidents occurring on the study stretch is

fatal accidents

Accidents are more frequent in August, September and October

Vehicle involvement in crash:

Light Motor Vehicles (LMV) 60 percent

Heavy vehicles 21 percent

Motor cycles are 19 percent

Even though major share of the traffic fly on the road are Two wheelers

(around 46%).

Victims in the road accidents:

Pedestrians 43 percent

Passengers 36 percent

The road crashes found to be concentrated between 12:00 to 14:00

hours (accounting for 23 %) and 17:00 to 19:00 hours (accounting for

17 %) of the total crashes
