Abstract
The city is a place of high concentrations of people who are subject to frequent displacement for various reasons. Means of transport are therefore very necessary to facilitate these daily trips. Modern life has multiplied these movements and tends to reinforce the distances to be covered. However, with the increase in the urban population and the vehicle fleet, we are witnessing congestion problems with considerable loss of time. The urban road in Bujumbura is ill-suited to the traffic it has to withstand in relation to all the means of transport superimposed on the same track. The growth of the vehicle fleet, the poor condition of the roads, their structure, the absence of bus stops, the insufficiency of adequate road signs increase the number of traffic accidents.
The overall objective of this work is to contribute to the improvement of road safety in Bujumbura Town Hall. To achieve this goal, three specific goals have been set. The first specific objective is to identify the causes of road accidents in the city of Bujumbura in order to prevent the risks associated with them. The second is to show that the growth of the car park in the city of Bujumbura is obvious, while the last allows to assess the reception capacity of the urban road network in order to prevent feel the solutions that can increase its capacity to respond to surplus traffic.
As part of this study, two hypotheses were put forward : H1. Road accidents are more frequent on primary roads. The superimposition of the different means of transport on the primary road is the main cause of these accidents.
H2. The increase in the vehicle fleet is the cause of the accidents and congestion observed in the city of Bujumbura.
The methodology used during this work consists of a qualitative approach based on the technique of direct observation. The results of this research showed that the primary roads of Bujumbura are saturated during peak hours (from 7 to 8 a.m. and from 5 to 6 p.m.) and that 67.5 of the accidents occur following collisions between two vehicles while overall, 87.3 of the accidents involve the vehicle component. Also, the cases of rolling accidents occur differ depending on the type of track. Thus, during the year 2019, 50.5 of accidents occurred on primary roads, 43.5 of accidents on secondary roads and the remaining 6 occurred in crossroads.
