    Introduction: This research examines the effectiveness of point-to-point speed cameras in Thailand compared with spot speed camera enforcement, which is widely used in the country. Method: The evaluation includes the speed control’s efficiency by observing the 85th percentile average speed of drivers on the road; the speed detection rate; conducting a comparison with spot speed camera enforcement; and a cost effectiveness analysis of this measure. Results: After speed detection using point-to-point cameras were employed during which warning tickets were issued in many days of experiment, the 85th percentile average speed in the controlled area decreased by 10 km/hr, with a maximum decrease of 20 km/hr. When comparing the detection rate of the two camera models, point-to-point cameras could detect 95 % of drivers’ driving speed, with 45 % of the detected drivers identified as speeding drivers, while spot speed cameras were only able to detect 10 % to 20 % of speeders. Drivers traveling through the area with point-to-point cameras were more likely to drive at a constant speed throughout the average speed detection area. Practical Applications: The point-to-point camera system is determined to be quite cost-effective.
