TRAFFIC CONTROL DEVICES INVENTORY
Study Objective
The main objective of this study is to identify, classify, and record various traffic control devices
along the survey route(s) (during off peak hours).
Need for the Study
Traffic control devices (signs) are installed along travel routes to facilitate orderly and predictable
movement of all traffic. These devices provide guidance and warning as well as insure the safe
and informed operation of individual vehicles using the road system.
Study Components
In conducting a traffic control device inventory, the following signs are identified, classified, and
recorded: Regulatory Signs, Warning Signs, Guide Signs, Recreational and Cultural Signs, and
Construction and Maintenance Signs
Field Work and Data Collection
The traffic control devices data in the field are collected along the designated roadway. The signs
installed on both sides of the street are recorded. The data collected are the type of traffic control
device, color, shape, code, and condition. For future reference, the direction of travel such as
eastbound, westbound etc. are also recorded. In practice, the data collection is done by videotaping
the street signs. The collected video data are analyzed in the office and entered into a software
developed specially for traffic control devices. For maintenance and identification purposes, the
field data are used in practice.
