Highway Accident

Posted by aditya | 10:12 PM | | 1 comments »

The problem of accident is very acute in highway engineering due to complex flow patterns of vehicular traffic, presence of mixed traffic and pedestrians. Traffic accidents may involve property damages, personal injuries or even casualities. One of the main objectives of traffic engineering is to provide safe traffic movements. Hence the traffic engineer has to carry out systematic accident studies so that the basic causes of accidents are investigated and preventive measures are taken in terms of design and or/control

Various causes of accidents may hence be listed as given bellow:
a. Drivers
Excessive speed and rash driving, violating rules and regulations, failure to see or understand the traffic situation, sign or signal, temporary effects due to fatigue, sleep or alcohol

b. Pedestrians
Violating regulations, carelessness in using the carriageway meant for vehicular traffic

c. Passengers
Alighting or getting into moving vehicles

d. Vehicle defects
Failure of brakes, steering system, tyre bursts or any other lighting problems.

e. Road condition
Slippery or skidding road surface, pot holes, ruts and other damaged conditions of the road surface

f. Road design
Defective geometric design like inadequate sight distance, inadequate width of shoulders, improper curve design, improper lighting.

g. Weather
Unfavourable weather conditions like mist, fog, snow, dust, smoke or heavy rainfall which restrict normal visibility and render driving unsafe.

h. Animals
Stray animals on the road

i. Other causes
Incorrect signs or signals, gate of level crossing not closed when required, ribbon development, badly located advertisement boards or service station etc
