Factors and motives of unsafe behaviors of road users.

A questionnaire to measure factors and motives of unsafe behaviors of road users was constructed. This study tool was applied on a final sample of 5586 drivers in twelve out of forty eight districts in Algeria. The aim of the present study was to sort out the different factors and motives that make road users opt for the unsafe behaviors. The latter were determined mainly on the results of a previous study carried out on a final sample of 7058 drivers in twelve out of forty eight districts in Algeria in order to find the most frequent and dangerous unsafe behaviors of road users. The main unsafe and dangerous behaviors were then used in the present study. Friedman ranking means test was applied to rank the factors and motives selected under each unsafe behavior of road users. The whole results were summarised in seven axes of factors and motives causing: dangerous manoeuvrings by drivers, aggressive behaviors by drivers, negligence and ignorance of maintenance principals by drivers, lack of responsibility and engagement by drivers, cyclists and motorcyclists and their companions, as well as pedestrians and workers of road maintenance. The results are discussed in view of the previous studies and many recommendations have been made.
