Automated Traffic Enforcement (ATE) on the Primary Highway System
ATEs in Iowa• Davenport…………….RLR & Speed• Cedar Rapids………… RLR & Speed• Des Moines…………… RLR & Speed• Sioux City…………….. RLR & Speed• Muscatine……………...RLR & Speed• Council Bluffs…………. RLR• Clive…………………...RLR • Ft. Dodge……………...Speed• Windsor Heights………Speed• Polk County……………Speed
Why is DOT Involved?• Iowa Code 307.2 • DOT responsible for planning, development, regulation and
improvement of transportation in the state.
• Iowa is the only state:• Local Jurisdiction can get ATEs by simple majority vote• Permanent speed cameras on the interstate
• ATEs can be Effective if Used in the Right Places• But…Research is mixed
• Public Trust
• Expensive from a Societal Perspective
History
• DOT Published ATE Guidelines - June 2012• Met with and Gathered Input from Cities - Sept 2012
• Published in Iowa Administrative Bulletin - Oct 2013• Rules Committee @ Capital - Oct 2013• Public Hearing & Written Comments - Oct/Nov
2013• Iowa DOT Commission – Approved - Dec 2013• Rules Committee @ Capital - Feb 2014• Adopted - Feb 2014
General Principals1. Primary Highway System only2. Only considered after other engineering and
enforcement solutions have been explored and implemented
3. Should not be used as a long term solution4. Fixed and mobile systems5. Limited use on the interstates6. Only used in high-crash, high-risk or school zones7. DOT Provide Objective Oversight
DOT – no authority to own/operate any ATE systems DOT – shall not receive any $
Justification Report(new installations only)
• Conduct an Engineering Safety Assessment
• Determine Critical Traffic Safety Issue(s)• Develop list of Countermeasures• Implement some Countermeasures
• Low cost, least intrusive/controversial• Why ATE is needed
Minimum Requirements• Signage• Calibration• Safe Environment for Motorists
• Do not impede or interfere with free flow traffic• Do not create visual obstruction• Not placed within 15 ft. of an interstate (unless
shielded)• Not within 2 ft. of back of curb• Not placed in a work zone• Not placed close to a speed zone change
• Traditional Enforcement – continue
Annual Report• Crashes – Before and After• Impact of ATE on Speeds or Red-Light Running• Number of Citations• Anything else to show they are effective• Provide by May 1 of following year
DOT Review of Annual ReportDOT will evaluate Annual Report to determine continued need, modification, etc. for ATE system
• Are the systems effective?• Are they in compliance with these
rules?• Consider other safety
countermeasures?
