Abstract
A four-button (police, ambulance, fire, service) emergency radio call box system was installed by the Texas Highway Department, on an eleven-mile section of I45 in Houston. This report evaluates the system in terms of usage, maintenance, driver accepance, service offered, and cost effectiveness. Stopped vehicle studies were conducted to determine the magnitude and characteristics of the stopped vehicle problem.| Rate of usage of the system was found to be 6.3 calls per million vehicle-miles or 2050 calls per year. The benefit-cost ratio was estimated to be 1.5 indicating the system is cost effective.
