STUDY OF THE EFFECTIVENESS OF REDUCED VISIBILITY GUIDANCE TECHNIQUES. VOLUME II. EQUIPMENT SURVEY

A study was performed to evaluate the effectiveness of reduced visibility guidance systems and operating strategies; and determine, if possible, which factors of system design contributed to system effectiveness and which approach is economically feasible for a specific highway condition. Data were assembled and analyzed from seven existing reduced visibility systems. A utility/cost model was generated which permits quantitative comparisons to be made between systems. A "measure of need" index was generated to make comparisons between the seriousness of the hazard at different locations. The study resulted in a methodology which allows a reduced visibility problem to be quantified and permits resources to be allocated in a systematic way in proportion to the seriousness of the hazard. The methodology itself has been published by the FHWA as Implementation Package Number 79-2. This volume consists of the Equipment Survey, which is the second of a two volume Final Report series. The first volume is the Final Report itself, identified by the following number: FHWA-RD-78-119. (FHWA)
