• 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

• 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

• 1. Primary Highway System only
• 2. Only considered after other engineering and

enforcement solutions have been explored and implemented

• 3. Should not be used as a long term solution
• 4. Fixed and mobile systems
• 5. Limited use on the interstates
• 6. Only used in high-crash, high-risk or school zones
• 7. DOT Provide Objective Oversight

 DOT – no authority to own/operate any ATE systems  DOT – shall not receive any $

• 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

• 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

• 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?
