The present work reports an investigation on the speed characteristics of vehicles on a typical Indian Highways. Speed of vehicle is influenced by several factors like roadway features, vehicle types, mixed traffic condition, lane behavior and presence of vulnerable road users due to proximity of roadside built-up areas. A spot speed survey was carried out on several identified segments, which indicated that there were violations in speed from the posted speed limits. The level of adherence was found to be the least for cars, followed by LCVs and trucks. The violations are maximum at school zones, and minimum at market areas. The effectiveness of different speed control treatments was evaluated by introducing a parameter termed as ‘Measure of Effectiveness’, considering operating speed, measured speed and posted speed limit. Based on the measure of effectiveness of different speed control treatments, recommendations were made for creating safe speed environments along the highways.
