Repair and maintenance models for highway traffic control devices

Abstract

The maintenance of highway traffic control devices faces problems based on the conventional and experimental methods. To resolve the above mentioned complexity, this paper sets forth mathematical models which can provide an optimum interval for non-operational devices, considering the financial limitations. For the optimized selection of various marking materials another model has also been presented. This paper has also tried to propose an appropriate management system for the maintenance of traffic control devices, along with the development of computer software for control devices, identifying the necessary procedure, time, tools, and manpower. The computer software and the mathematical models presented leads to optimization of the repair and maintenance operations
