PROJECT BACKGROUND<br />
• Strategic Highway Safety Plan<br />
(SHSP) Issue Area #4 : Reduce<br />
<strong>Speed</strong>-Related Crashes<br />
• <strong>Wisconsin</strong> does not have<br />
statewide speed zone<br />
management guidelines to help<br />
state/local engineers with<br />
consistent ways to enforce speed<br />
limits<br />

<strong>Wisconsin</strong> State Statutes<br />
• <strong>Wisconsin</strong> State Statute 349.11 (1)<br />
– <strong>Speed</strong> limits for state and local roadways shall be<br />
changed from statutory speeds to modified<br />
speeds “upon the basis of a traffic and<br />
engineering investigation” (e.g. speed study)<br />
• Includes speeds within parameters set in SS 349.11 (3)<br />

<strong>Wisconsin</strong> State Statutes<br />
• <strong>Wisconsin</strong> State Statute 349.11 (3)<br />
– Only WisDOT has authority to modify speeds on<br />
STH system<br />
– Local governments have authority to modify<br />
speed limits on local roadways within constraints<br />
• WisDOT approval is not required under these<br />
conditions<br />
– WisDOT approval required on modifications to<br />
local roadways outside of constraints<br />

<strong>Speed</strong> Study Process<br />
• Six steps to performing a speed study<br />
1. Identify and inform stakeholders<br />
2. Collect location-specific data<br />
3. Analyze data and develop conclusions<br />
4. Develop speed zone recommendations<br />
5. Report results, conclusions, and recommendations<br />
6. Seek stakeholder support<br />
• Monitor/Evaluate <strong>Speed</strong> Zone<br />

SPEED MANAGEMENT GUIDELINES<br />
Conducting a <strong>Speed</strong> Study<br />
• Step 1: Identify and Inform Stakeholders<br />
– If study is warranted, state/local authority shall<br />
inform primary stakeholders of speed study<br />
• Brief local stakeholders of speed study process<br />
– Coordination with local stakeholders is vital<br />
throughout speed study process<br />

Conducting a <strong>Speed</strong> Study<br />
• Step 2: Collect location-specific data<br />
– Serves as foundation to make conclusions and<br />
recommendations for speed study<br />
– Objective: Gather data about study area<br />
– Outcome: Have comprehensive, adequate data to<br />
analyze study area<br />
• Data collection process involves<br />
not only collection of speed data<br />

Conducting a <strong>Speed</strong> Study<br />
• Step 2: Collect location-specific data (cont’d)<br />
State and local speed zone studies shall collect<br />
the following location-specific data:<br />
– Existing vehicle speeds<br />
– Crash data for the past three to five years<br />
– Roadway geometrics<br />
– Traffic control and posted speed limits<br />
– Land uses and access points<br />

Conducting a <strong>Speed</strong> Study<br />
• Step 2: Collect location-specific data (cont’d)<br />
Supplemental data should be collected to<br />
further understand current traveling conditions<br />
within the study area<br />
– On-street parking<br />
– Pedestrian / bicycle use<br />
– Proximity to schools<br />
– Current level of speed enforcement<br />

Conducting a <strong>Speed</strong> Study<br />
• Step 2: Collect location-specific data (Cont’d)<br />
Factors to consider before collecting speed data<br />
– When? (Day and time to perform the speed study)<br />
– Where? (Study location)<br />
– Who? (Observer location and position)<br />
– How? (Data sample characteristics)<br />
