Improved Traffic Control Devices
General Description:
Improved Traffic Control Devices, such as sign improvements, signals, and pavement markings, can better notify motorists of regulations, fees, services, road conditions, wildlife, or any other relevant information. There are three types of traffic signs: regulatory signs, warning signs, and informational signs. Size, shape, uniformity, and placement are all important considerations with traffic control devices. All traffic control devices must meet the Manual on Uniform Traffic Control Devices (MUTCD) standards.
Effects of Solution:
¨ Increase Passenger Throughput
¨ Increase Roadway Capacity
þ Manage System Efficiency (Can improve vehicle interactions)
¨ Reduce Local Demand
Improvements may be made with better traffic control, but there must be additional steps taken to improve conditions. Traffic control is a form of system management.
Examples of Implementation:
No specific examples available at the time of publication.
Cost/Financial Information:
(Cost/financial information is estimated, and will vary based on size and scope of project, number of units, etc.)
Typical costs for signs start at approximately $200 (uninstalled) and increase depending on the number of signs per post location and installation factors.
Please see the Pavement Striping Techniques fact sheet for striping cost information.
