Abstract

Speed is an important risk factor for road traf c crashes. We studied the prevalence of speeding in three major cities in Southeast Asia (Bandung, Bangkok and Ho Chi Minh City-HCMC), and factors associated with it. The study was conducted between July 2015-September 2016 using a standardized protocol and data collection tool. Observation locations were selected through systematic sampling. Speed was measured using a microwave radar gun on weekdays and weekends, and 5 times during each day. Descriptive and logistic regression analysis was done separately for each city. 623,744 vehicles were observed (Bangkok:61.8%; Bandung:36.0% and HCMC:2.2%). 21.8% vehicles were found to be speeding across the three cities. The prevalence of speeding was 7.8% in Bandung, 30.7% in Bangkok, and 1.9% in HCMC. When adjusted for other variables, compared to motorcycles, SUVs were more likely to be speeding in Bandung (aOR:1.97); large trucks (aOR:7.69) in Bangkok; and light trucks in HCMC (aOR:2.39). In Bandung, speeding was mostly observed in the peri-urban parts of the city (94.5%). Speed was likely to be highest during non-peak hours of the day in HCMC (aOR:3.08). High prevalence of speeding was observed in the three cities, making this an important risk factor for road safety in urban Southeast Asia.

FINDINGS, especially with regards to variations by vehicle type, times of day, days of week, and types of roads would be useful for city governments and traf c police to better plan strategies to improve road safety in these cities.
