•Red light cameras
•Pavement safety upgrades
•Guardrails
•Neighborhood traffic calming
Traffic Engineering – SafetyTraffic Signals
Upgrade signalizedintersections to reduce accidents.
Adjust timing.
Add left turn phases.
Change signing or pavement marking.
Signal Timing:
A maximum 4 sec. amber is used, with all red for additional clearance time.
Traffic Engineering – SafetyTraffic Signals
Traffic Engineering – SafetyPedestrian Signals
Explain how to use push buttons
Traffic Engineering – SafetyPedestrian Crosswalks
Pedestrian Crosswalks:
Pedestrian activated flasher and high visibility crosswalk.
Traffic Engineering – SafetyTraffic Signs
Traffic Signs:
Retro-Reflective sheeting helps communicate with motorists to prevent crashes, relay information & facilitate uninterrupted traffic flow.
Legibility Distance and Target Value
Stages of Sign Perception
Object Detection“something is there”
Color Recognition“it is red”
Shape Recognition“it is an octagon”
Text / Symbol Legibility“it says stop” STOP

Working with schools to help expose young children to the traffic
engineering profession is just one way.
Think of ways that you can do it... and then do it! You’ll find it a
rewarding experience.
In conclusion, there are many ways that we, as professionals, can provide outreach to the public.
