COMPUTER SURVEY OF PASSING ZONES PUTS PRECISION IN 1500-MILES STRIPING JOB

The use is described of computer technology coupled with peripheral instruments to provide accurate determinations of passing/no passing zones. The computer is programmed to construct a 2-dimension profile analysis of the various curves along the entire length of an established line of sight distance equivalent to the 85th percentile of design speed. As the vehicle travels the highway, the system computes the various equations for placement of zones in real time and provides computer printout permanent records of all zone locations. Computer no passing zone information is transmitted directly to a zone code paint vehicle, where the information is automatically processed by a paint control systems for highway placement of Mini-Code Patterns. The processing of taped information to provide straight line maps and a composite graphic presentation of the highway is described.
