TRUCK ESCAPE LANES ON MOUNTAIN ROADS

An investigation is reported of the use of truck escape lanes. Details are given of the construction of 2480 ft long, gravel escape lane (in Utah) which was 13 ft wide with a 10 ft and 6 ft wide shoulder. The maximum depth of the pea gravel was 12 in. and was composed of material passing the one-in. screen and retained on the #4 sieve. Information was collected concerning the use of the escape lane. An agreement to direct the surveillance and analysis of the data collected was made with the Utah Auto crash research team. Information gathered from the maintenance foreman indicates that 15 trucks used the lane for emergency stops in the first 15 months. This escape lane has proved that a pea gravel arrester bed is an efficient and effective method of stopping trucks that not have operating brake systems.
