DECELERATION SIGNAL SYSTEM STUDY (AS REQUIRED BY AB 1260, 1972 LEGISLATIVE SESSION)

The results of the experimental study of the Cyberlite deceleration signal on Yellow Cabs in San Francisco are as follows: 1. Collisions with the rear of cabs were reduced by 60% during the 4-month study period. 2. Complaints in 48 letters stated that the Cyberlite was too bright, was particularly irritating at night, in dark wet weather, and gave an aggravating signal because of cab drivers riding the brakes. 3. Opinion surveys of traffic officers paralleled the comments in the letters. Theu expressed concern about peripheral accident hazards due to lane changes of drivers escaping from behind the bright lights and about the irritating sea of lights that could occur in congested traffic if many vehicles were so equipped. 4. Specific requests to three Bay Area Police Departments for a report of each collision in which Cyberlite was mentioned as a peripheral cause resulted in zero reports. Recommendations relating to deceleration signals are also presented.
