Commercial drivers are usually observed with more speeding behaviors than other cohorts. Some of their speeding behaviors occurring under specific conditions may cause more hazards. Hereby, there is a need to verify the hazard caused by different categories of speeding and benefit the anti-speeding countermeasures. This study treats the speeding-related harsh decelerations (SHDs) as a surrogate measure of safety. The speeding distance ratios in different categories (i.e., speeding patterns) and operational attributes are modeled as the risk factors. An Accelerated Failure Time (AFT) model is developed to relate the risk factors to the safe operation hours which means the average duration between the adjacent SHDs. The results indicate that speeding greater than 50% in daytime and speeding greater than 20% on peak hours/at night significantly decrease the safe operation hours on roads with a high-speed limit (≥60 km/h). In addition, it is difficult to keep long safe operation hours when commercial drivers speeding on nighttime roads with a lower speed limit (≤50 km/h). Conversely, speeding less than 20% is not linked to the deterioration of driving safety in all the scenarios.
