According to the different characteristics of roads, each road type has different speed limits from the safety point of view, which are posted along the roads at regular intervals. Yet, it is observed that over-speeding is one of the main reasons for fatal road accidents. Therefore, the question arises that whether the posted speed limits are appropriate, whether the drivers comply with the posted speed limits, and if not complied, then whether the violations of posted speed limits are by chance or not. The appropriateness of the speed limits requires a separate research, but this paper reports the findings from an investigation carried out along two arterials in Kolkata, West Bengal, to address the other two questions. The drivers’ tendency to violate the posted speed limit has been modeled using Binary Logistic Regression technique to reveal the site-specific factors that affect the posted speed limit violation. It is observed from the model that with increase in time headway between vehicles, the violation of speed limit increases. More violations are expected along roads with higher number of lanes due to the availability of more road space free from the influence of leading vehicles. Bus and truck drivers have higher tendency to violate the posted speed limits than the passenger cars and motorized two-wheelers.
