Section 19-151-5 - Studies required(a) To determine if a traffic-controlled intersection should be equipped with a system, the State or county shall conduct a study to acquire: (1) A baseline average of the number of red light traffic-control signal violations committed by motor vehicles in accordance with HRS section 291J-4(c)(2); and(2) At a minimum, the most recent three years available of motor vehicle crash data involving fatalities, injuries and property damage at intersections being considered for the installation and operation of a system.(b) The State or county, prior to the installation and operation of a system at an intersection considered for enforcement by the system, shall conduct a comprehensive engineering study to identify conditions that may be present that contribute to red light violations, such as, but not limited to: (1) The grade of an intersection approach;(2) Poor visibility that reduces a motorist's ability to identify signs, signals or other traffic control devices at intersections;(4) Traffic-control signal timing.(c) The State or county shall implement appropriate countermeasures for intersections identified in their comprehensive engineering study that may correct conditions that contribute to red light violations prior to the installation and operation of a system. Such countermeasures considered shall consist of, but not be limited to:(1) Improving signal head visibility;(2) Additional signal heads;(4) Appropriate yellow intervals;(5) Signalized intersection warning signs;(6) Advanced yellow flashing lights;(7) Adjusting the approach speed;(8) Traffic signal coordination;(9) Advanced vehicle detection; and(10) Removal of on-street parking.Eff 12/26/2021 (Auth: HRS §§ 291J-4, 291J-13) (Imp: HRS § 291J-13)
