AbstractSpeeding is one of the most prevalent factors contributing of deaths and injuries in road crashes. Speeding is a local, state, and national problem because the potential of crash and the injury severity increase as driving speed increases. The essence of problem is that the individual speeding driver frequently experiences a positive outcome of speeding. However, some of the common reasons for speeding were explained; for example, driving fasts give driver extra pleasure and travel time is reduced when drive faster. According to the speed problem that mentioned earlier, speed control is at the core of the most recent thinking about road safety. The speed management strategies to reduce speed have been employed to prevent road accident. In order to successful implementation of speed management strategies, it is important to determine the acceptability of specific strategies which influencing from individual drivers' attitudes because the behavior of driver is the main causal factors of accident. A methodology has been developed using order probit models to evaluate drivers' attitudes towards speed management strategies. These models can determine drivers' preferences for different speed management strategies and help planners to investigate the effect of individual characteristics on drivers' attitude. This study based on a questionnaire survey from a random sample of 1364 drivers obtained from seven provinces in Thailand. The implementation of these strategies can be divided into two different roads; urban and interurban road. On urban road, the proposed strategies consist of two categories; speed information and engineering measures. Speed information campaign was found to be more popular than engineering measures. Among all five possible strategies on urban roads, introduction of rumble strips rated as the most desirable approach whereas roundabout was found to be the least popular solution to the respondents. Order probit models revealed that drivers working as a driver showed a negative attitude towards introducing of roundabouts, speed humps and speed limit signs. Highly educated drivers were strongly supportive the introduction of speed limit signs and speed humps. High speed drivers were found to express a strong agreement with introduction of rumble strips but show a disagreement with speed warning signs, speed limit signs and speed humps. Among four categories of suggested measures on interurban roads, speed information campaign was found to be the most desirable and smart vehicle design to be the least desirable categories of strategies. Among all the twelve proposed strategies on interurban roads, the introduction of rumble strips were found to be the most desirable approach while intelligent speed adaptation (ISA) with mandatory was found to be the least welcome solution to the drivers. Order probit models also revealed that high speed drivers show a strongly negative attitude towards all speed management strategies but express a positive attitude towards the introduction of rumble strips. Highly educated respondents expressed a strongly positive attitude towards introducing of speed limit signs and both ISA with mandatory level and voluntary level. Moreover, drivers having high education were also found to approve of all proposed speed enforcement strategies except for introducing of police checkpoint.
