1. EX-1 Intersections & Interchanges Improved Traffic Signal Control Ramp metering Intersection Collision Avoidance Systems Automated Enforcement

2. EX-2 Improved Traffic Signal Control Purpose: Reduce signal-related congestion, delay, & crashes Description: Sensors & control equipment enable timing to adjust based on conditions, and to be coordinated with adjacent jurisdictions to smooth flow

3. EX-3 Improved Traffic Signal Control Example: Phoenix - Improved Signal Coordination 21 signals along corridor within two jurisdictions 3 signals adjusted - moved the break in progression southward Improved travel speeds Reduced average number of stops Resulted in 6.7% reduction in crash risk

4. EX-4 Pedestrians & Bicycles Pedestrian Detectors In-Pavement Lighting Countdown Signal Heads Animated Eyes Display Bicycle-Actuated Signals

5. EX-5 Pedestrian Presence Detectors Purpose: Improve safety at pedestrian crossings by accommodating those who need more time Description: Sensors detect pedestrians waiting or crossing, extend signal phase accordingly

6. EX-6 Pedestrian Presence Detectors Example: In-Pavement Lighting Amber lights embedded in pavement facing oncoming traffic Pedestrian activates system – push button or automated detection Lights flash at a constant rate warning motorists that a pedestrian is ahead Increases driver awareness of pedestrians

7. EX-7 Highway-Rail Grade Crossings Second Train Warning Systems Enforcement Systems Information Dissemination Systems Traffic Signal Control

8. EX-8 Second Train Warning Purpose: Reduce dangerous driver & pedestrian behavior when crossing is used for trains in rapid succession Description: Signs notify drivers and pedestrians that barriers remain lowered due to a “second train coming”

9. EX-9 Second Train Warning Example: Light Rail Transit Grade Crossing 26% reduction of vehicles crossing tracks between trains Decrease in drivers moving their vehicles under the rising crossing gate before realizing there was a second train

10. EX-10 Road Weather Environmental Sensor Stations Mobile Sensors Information Dissemination Treatment Strategies Traffic Signal Control Variable Speed Limits

11. EX-11 Road Weather Management Purpose: mitigate the effects of rain, snow, ice, fog, high winds, flooding, tornadoes, hurricanes, & avalanches Description: Advisory, control, & treatment strategies to promote safe travel under adverse weather conditions

12. EX-12 Road Weather Management Example: Warning System in Ft. Lauderdale Warns of wet pavement on a ramp Uses in-pavement sensors Activates flashing beacons on sign at ramp entrance Significant reduction in speeds during wet pavement conditions

13. EX-13 Work Zones Portable Traffic Management Systems Traveler Information Systems Speed Enforcement & Display Systems VMS Merge Point Notification

14. EX-14 Portable Traffic Management Systems Purpose: Improve safety by increasing driver awareness of traffic conditions in work zones Description: Collect, process, & display work zone traffic information to the road user

15. EX-15 Portable Traffic Management Systems Example: Minnesota Work Zone Video Traffic Surveillance Traffic Control Center located at the area TMC VMS Wireless communication between components Variability of speeds decreased 70% within the work zone Speeds approaching work zone decreased by 9 mph
