| Abstract | Traffic accident is not simply a loss of one single life but it is an unrecoverable setback to
all those concerned, furthermore, its a loss to the nation's economy. Being Transportation
Engineers, ensuring safety should be the first priority. For this, all this research is about.
The research mainly focuses on the traffic accident analysis for two of the busiest traffic
corridors in Karachi, Pakistan. The prime purpose is to uncover the characteristics of the traffic
accidents on the selected corridors in various ways and scenarios and to get line of action towards
attainment of the traffic safety in the city. Furthermore, to develop a model for evaluation of a
given road section as Hazardous or Safe, based on various traffic, geometric and road
environment conditions by integrated use of cluster and discriminant analyses.
The results from the analysis show 36% of the accidents involve pedestrians, while 55%
of such accidents occur while pedestrians are crossing roads. The lack of pedestrian facilities is
one of the prime reasons for such accidents. Although less number of females are involved in the
accidents, but social setup of the country makes this population fraction more critical. In various
types of intersections T-Type intersections are most critical, specially when operated under
uncontrolled conditions. In some cases on corridor 2, signalized intersections are also critical, the
reason is their counterfactual timings. The visibility, lane marking, lane width and traffic volume
are the most sensitive parameters contributing towards traffic safety along the roads. On overall
basis 25% of corridor I and 24% of corridor 2, are hazardous.
The main conclusions of the study include recommendations for Traffic Engineering
Bureau (TEB) to modify their accident reporting format. Furthermore, recommendations for road
user safety are also discussed. The need of traffic safety awareness program is also stressed upon.
This is necessary, so that the road users can recognize their rights and responsibilities in the
traffic system. Since traffic volume has very high relation with accident rates, therefore
recommendation is made to distribute traffic on the whole network of the city by adopting
various Traffic Demand Management (TOM) Techniques. Furthermore, care should be given to
maintain streets lighting and lane markings for better safety conditions. |
