Abstract

Objectives: Interurban roads account for a significant proportion of traffic deaths in developing countries. In this pilot study, hazard perceptions of interurban road sites involved in ≥3 injury road traffic crashes were compared with those not involved in road traffic crashes on the same road sections.
Settings: Karachi-Hala (Pakistan) and Yaoundé-Douala (Cameroon) road sections were the main study settings.DataVideos of 26 high-risk sites and 26 low-risk sites from Karachi-Hala (Pakistan) and Yaoundé-Douala (Cameroon) roads, matched for the road section, were shown to 100 voluntary Pakistani drivers. Variations in perceived site hazardousness and preferred speed for each site pair were assessed.
Analyses: Factors associated with incorrect hazard perception of high-risk sites (perceived as safe) were assessed by multinomial logistic regression analyses.
Results: Drivers reported a higher hazard perception and a lower preferred speed for high-risk sites than for their matched low-risk sites in less than half of pairs (n=12, p≤0.02). Factors associated with increased likelihood of identifying a high-risk site as safe were as follows: flat road profile (adjusted OR=2.00, 95% CI 1.55 to 2.57), intersections (OR=1.96, 95% CI 1.43 to 2.68), irregular road surface (OR=3.56, 95% CI 2.68 to 4.71), nearby road obstacles (OR=2.57, 95% CI 1.96 to 3.39) and visible rain (OR=1.85, 95% CI 1.48 to 2.32).
Conclusion: The methods used in this study might be useful in prioritising cost-effective improvements at high-risk sites.
