Everything in presentation is available, though not all in use

Obstacles:– Finances: Can’t afford to replace all old systems with new equipment or afford new

systems

– Inter Agency Trust and Cooperation: Turf issues, differing priorities, who has control

– Public Acceptance: Politicians won’t support thing constituents are opposed to

– Legal Challenges: Groups can challenge things in court, even if public supports

Agenda








Traffic Enforcement Through Technology

“Photo Cop”

Traffic Enforcement camera– Speed control– Red light running– Bus Lane enforcement– Toll roads

http://www.iihs.org/video.aspx/info/auto_enforcement

http://www.iihs.org/video.aspx/info/auto_enforcement


Traffic Enforcement Through Technology – why needed?

1,000 fatalities (nationally) per year due to “red light running”

13,000 fatalities (nationally) per year related to excessive speed

Multiple injuries and accidents due to these violations

Limited manpower to address the problem (enforcement efforts are often short duration)


Traffic Enforcement Through Technology – Benefits

Multiple research studies have shown:

– Increased compliance w/ speed limits

• 80% reduction in vehicles exceeding the posted speed by 10 mph where this has been used

– Reduction in the number of fatalities and severity of accidents

– Identifies and deters those that break the law

Enhances enforcement efforts

A fair, objective, and consistent application


Traffic Enforcement Through Technology – Obstacles

Legal challenges to the use of monitoring equipment– Invasion of privacy?

– Ticket issued to the vehicle owner, not the driver

Laser jamming devices on vehicles

Falsified license numbers on vehicles


Traffic Enforcement Through Technology – MN Experience

Minnesota Supreme Court Strikes Down Red Light CamerasThe Minnesota Supreme Court delivers a unanimous decision striking down the legality of red

light cameras.

The Minnesota Supreme Court today delivered the highest-level court rebuke to photo enforcement to date with a unanimous decision against the Minneapolis red light camera program. The high court upheld last September's Court of Appeals decision that found the city's program had violated state law.

The supreme court found that Minneapolis had disregarded a state law imposing uniformity of traffic laws across the state. The city's photo ticket program offered the accused fewer due process protections than available to motorists prosecuted for the same offense in the conventional way after having been pulled over by a policeman. The court argued that Minneapolis had, in effect, created a new type of crime: "owner liability for red-light violations where the owner neither required nor knowingly permitted the violation."

Minneapolis Code of Ordinances sections 474.620 to 474.670, which make the owner of a motor vehicle guilty of a petty misdemeanor if the vehicle is photographed running a red light, are invalid because they are in conflict with the Minnesota Traffic Regulations, and specifically with Minn. Stat. Section 169.06, subd. 4(a) (2006), and Minn. Stat. Section 169.022 (2006).

Rochester Winter Maintenance Support System

Truck Mounted Computer

Antennae

Temp Sensor

Wireless Comm Link



The Maintenance Decision Support System serves maintenance staff– decision support tool – real-time weather / roadway conditions

Combined with information on maintenance vehicle resources (i.e. salt, sand, etc…) – MDSS recommends appropriate roadway maintenance application treatments / rates

MDSS assimilates data on road surface conditions from Road Weather Information Stations (RWIS)

On-board vehicle sensors report pavement temperatures– also allows for field staff observations on road visibility to be factored into the MDSS

recommendation for appropriate maintenance treatments. With all sources of information taken into account, MDSS offers users various treatment

options– such as “optimal” treatments – where travel safety is prioritized higher than treatment

costs –– and “what-if” treatments – where the effects of several maintenance actions on

overall resources can be understood by the system user before recommending certain actions.

”The snow and ice-control practice of preventing the formation or development of bonded snow and ice by the timely applications of chemical freezing-point depressant.”

-- FHWA Manual for

an Effective Anti-Icing Program

What is Anti-Icing?



Stationary Anti-icing Systems

Fixed

Automated

Spray

Technology

Goal of F.A.S.T. System: “The early prediction of ice formation in its different forms (ice, black ice, frost, freezing rain, and snow) along with a time-efficient activation of the spraying system.”

45

Anti-Icing Chemical

Potassium Acetate

Low corrosionContains no chloridesEffective to -45 F (lab)Field Experience to -20 FNo agitation requiredEnvironmentally favorable to saltsDoes not refreeze

50



Flow meter for measuring amount of liquid dispensed per spray. Flexibility according different conditions The spray system executes up to 16 customer-configurable spray

progression to fit any specific weather situation and road condition. Active and Passive Pavement Sensors able to anticipate icy

conditions on the road by simulating them before they actually occur The concept of anti-icing instead of de-icing, which acts after the icy

condition has been generated attempting to melt the ice following its formation.

An AASHTO study, indicates it requires 3 times the chemical to remove ice as it does to prevent it from forming in the first place.
