摘要：	The majority of signalized junctions in Sweden operate as isolated junctions, employing gap extension and signal group based control known as LHOVRA technique. Incident reduction function was originally incorporated as part of LHOVRA (the "O"-function) and was intended for use at isolated junctions on high-speed roads as a means of reducing the number of vehicles in the dilemma zone and thereby reducing the number of red light drivers and rear-end collisions. This is achieved by detecting vehicles at the beginning of the option zone and postponing the decision to change to yellow. This study aims to improve the incident reduction function in three ways that build upon each other: firstly, by changing the detector location to be 110 m and 65 m instead of 140 m and 85 m; secondly, by placing a double-detector at the dilemma zone entry making the green time extension conditional on the speed of the vehicle passing the double-detector; and thirdly, by taking in the consideration the headway between two existing vehicles in the dilemma zone.
