Abstract:
Transportation engineering aims at creating the best route between two locations within three
considerations: safety, time, and cost. Drivers’ behavior at roads is one of the main
concerns for any traffic engineer for its effect on safety. To a large extent, the safe operation
of any system requiring direct human control depends on the level of behavior that the
human controller provides. The main objective of this topic is to Investigation on the impacts
of Bajaj driving behavior on traffic flow and safety. The study area is located in Bishoftu city.
The city covers 182.78km2 (18278 ha) with the total population of 201408. Data were
collected from survey questionnaire, where the number distributed questionnaire was 600.
The number of returned from respondent was 552, 460 (83.7%) males and 92 (16.7%)
females.
The participants’ (drivers) real application for these behaviors, 145(78.4%) of the
participant said that (rarely-Often) they drive speedy while they are angry, 20-50% of them
said that they lose their temper during speedy driving. More of traffic accidents can happen at
other section of the road. So LOS have not much effect on traffic accident, and the area with more
accident have less traffic volume, when it compared with driving behavior effect. It show that
generally of road accident and bad traffic flow is caused by human factors which refer to
the behavior of driving. Bajaj vehicle factor has the highest percentages for the cause of
road traffic accident. It was found that the highest driving impacts are, aggressive driving,
drive out of lane, inattention, and speeding, distracted driving, angry driving and wrong
turning and lane changing are identified. The main causes of bad driving habits related to
Bajaj drivers are, experience of the drivers, age of driver (younger drivers),low quality of
license giver agencies, road types (common road) with other vehicles. And the main causes
of traffic accidents, that are related to Bajaj driver driving behavior are, close following
and tailgating, lane violations and zigzag driving or passing, being unfocused and
distraction.
Finally it recommended that, Increase enforcement, Education and awareness for drivers
and pedestrians, separate the common roads of Bajaj and other vehicles, to force drivers
who repeat traffic violations to suspend their driving license and to attend training courses
concerning traffic laws and regulations, to encourage drivers to drive defensively and to
obey traffic rules and regulations in all circumstances.
