New and Experimental Technologies

2. 23. New Technologies
All technologies require a maintenance plan. With new technologies this is emphasized, since it is “new”. Any equipment used should be bench tested prior to implementation.

3. 23. New Technologies Truck Priority
Truck Priority is a system to grant trucks priority treatment at specified intersections
A means to improve the operation of heavy trucks passing through traffic signal controlled intersections on rural high-speed highways
Report

4. 23. New Technologies Work Zone Accident Reduction Deployment (WZARD)
Provides unaware drivers with advance notification of the presence of maintenance, work zone, incident management and law enforcement vehicles in order to reduce crashes and improve safety along a project corridor

5. 23. New Technologies
A primary goal is to put into place the infrastructure necessary to improve safety for snow/ice and other work zone operations
Other goals and objectives include
Reducing incidents by providing the traveling public with real-time information about corridor traffic operations between Rogers and St. Cloud, Minnesota

6. 23. New Technologies
The goals and objectives for the SCorE WZARD project can be grouped into three main areas:
Traffic Incident Management
Improve I-94 corridor safety during work zone operations
Improve safety for traffic incidents and/or traffic enforcement activities
Reduce the occurrence of snow plow/vehicle crashes
Reduce the occurrence of secondary incidents

7. 23. New Technologies Transportation System Efficiency
Improve traffic safety and mobility
Improve travel times along the I-94 corridor
Reduce I-94 corridor congestion
Manage recurrent peak period congestion, including weekend seasonal traffic
Reduce vehicle emissions

8. 23. New Technologies Public Communications/Traveler Information Report
Provide real-time traveler information along the I-94 corridor
Provide travelers with advance warning of maintenance operations upstream
Provide CCTV images to RTMC, District 3 Operations and State Patrol
Report

9. 23. New Technologies Speed Monitoring
A system used to monitor traffic speeds on the roadways
Every Federal Fiscal Year quarterly and annual speed monitoring reports are prepared by the OTST and submitted to the Federal Highway Administration (FHWA) Division Administrator

10. 23. New Technologies Wrong Way Detection
This includes a system used to detect vehicle traveling in the wrong direction on a traveled way.
Two or more loops are placed in the roadway as shown in Figure 33.

11. 23. New Technologies Intelligent Work Zones

12. 23. New Technologies Wildlife Warning System
Consists of two subsystems:
detector stations
signs
Detector stations approximately 150 to 400 feet
Uses pairs of infrared beams

13. 23. New Technologies Bridge Warning Height System
Detects over height vehicles moving toward obstacles such as bridges, tunnels and other overhead structures and individually warns drivers
An sign is activated when an over height vehicle is detected by the system
The purpose of this system is to detect over-height vehicles and warn the drivers of the impending problem

14. 23. New Technologies Fog Warning System
A highway visibility sensor that measures the density of roadway fog
Linked to traveler information systems
Has long been internationally recognized
Motorists can avoid tragic pile-up accidents caused by dense or patchy fog, which are often fatal

15. 23. New Technologies Warning of Stopped or Slow Traffic Ahead
Refer to the IWZ Handout
Warn of stopped vehicles in a construction zone

16. 23. New Technologies Water on Road System
A highway sensor that measures the presence of water on the roadway and is linked to traveler information systems
To warn drivers of water on a roadway advising them not to pass.

17. 23. New Technologies Tolling MnPASS
I-394 operates a High Occupancy Toll (HOT) lane
Carpooler's may use the lane for free
Single occupant vehicles can opt to pay a toll to use the lane
The toll charged varies according to conditions
Toll collection is automated (no manual fare collection)
The purpose is to improve travel times and reduce congestion
To provide an uncongested express lane for high occupancy vehicles and single-occupancy vehicles paying an electronic toll

18. 24. Experimental Technologies
Connected Vehicle
Connected Vehicle research has the potential to transform travel as we know it
Uses leading edge technologies
Advanced wireless communications
on-board computer processing
advanced vehicle-sensors
GPS navigation
smart infrastructure
others
Provides the capability to identify threats and hazards on the roadway and communicate this information over wireless networks to give drivers alerts and warnings

19. 24. Experimental Technologies
Electronic Tolling
A system for automated collection of tolls from moving or stopped vehicles through wireless technologies such as radio-frequency communication or optical scanning
ETC systems are classified as one of the following:
(1) systems that require users to have registered toll accounts
(2) systems that do not require users to have registered toll accounts
