  1. Automated Traffic Enforcement (ATE) on the Primary Highway System

  2. 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

  3. 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

  4. 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

  5. General Principals • Primary Highway System only • Only considered after other engineering andenforcement solutions have been explored and implemented • Should not be used as a long term solution • Fixed and mobile systems • Limited use on the interstates • Only used in high-crash, high-risk or school zones • DOT Provide Objective Oversight • DOT – no authority to own/operate any ATE systems • DOT – shall not receive any $

  6. 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

  7. 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

  8. 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 Report • DOT 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?
