Categorization of Road Accidents Related to the Default of Signaling: A Case Study of the Yaoundé-Douala Highway, Southern Cameroon

This chapter examines the types of road accidents caused by a lack of signposting, as numerous accidents have happened in Cameroon as a result of poor signposting. This investigation will take place on the Yaoundé-Douala motorway. Available The examination of each accident was made possible using field data collected in the years 2007, 2009, and 2011. It shows that 108 occurrences (about 20%) of the 569 accidents documented across a 114-kilometer stretch were caused by a failure or lack of signage. On the one hand, a clinical analysis revealed four collision scenarios, while on the other, seven were developed based on factors such as lack of signposting at crossroads, lack of vertical and/or horizontal alignment or a slightly raised bump, and lack of signpost for normal parking layouts or no parking at certain critical points.
