MDOT Local Safety Initiative 10
Michigan Legislative Highway Safety Initiatives
• 0.08 BAC Law (July 2003)500 lives saved yearly – nationwide($3.22 Million incentive to Michigan in Sept. 2003)
• Work Zone LawsSpeed Limits ~ Double Fines (1997)Andy’s Law (2001) ~ Increase Points (2002)Work Zone Defined (2003)
• Graduated Drivers Licensing(In effect April, 1997. Crashes involving 16 year old drivers dropped 25% in 1999).
• Primary Seat Belt Law (March 2000)
MDOT Local Safety Initiative 11
The Case for Traffic Safety . . . Michigan has . . .
• 122,000 miles of highway
• 101.8 Billion vehicle miles traveled in 2004
• 370,000+ crashes yearly• 100,000+ crash injuries
yearly• 1,000 – 1,200 fatalities
yearly
MDOT Local Safety Initiative 12
Unacceptable Cost in terms of . . .
• Loss of Life – 1,159 Michigan, 2004 (42,000 Nationwide)
• Economic Impact - $9.8 Billion loss to Michigan($230 Billion Nationwide)
• Every tragic eventinvolves someone’s family member!
MDOT Local Safety Initiative 13
AASHTO Safety Goal
1.5 Fatalities per 100 Million VMT, 2004(Michigan Fatalities – 1.1 per Million VMT)
The Goal? Reduce to
1.0 Fatalities per 100 Million VMT by 2008(Save 350 lives per year in Michigan)

Local Safety InitiativeA Year in Review
MDOT Local Safety Initiative 50
Program Successes
• To date the Local Safety Initiative has worked with 5 counties• 4 additional Counties going through initial
analysis• Including crash analysis within 11
cities/villages• Begin with County Engineer/Rep.
• Countermeasure suggestions provided
MDOT Local Safety Initiative 51
Commonalities…
• Larger/brighter signing• Additional signing on curves• Upgraded pavement markings
• Wider lines• Wet/night markings
• Cut back tree line/Improve clear zone• Remove sight distance obstructions at
intersections
MDOT Local Safety Initiative 52
Curves
• Improve signing• Improve delineation• Check superelevation
MDOT Local Safety Initiative 53
MDOT Local Safety Initiative 54
MDOT Local Safety Initiative 55
MDOT Local Safety Initiative 56
Upcoming Typicals
• Ultra Low Volumes• Defined by MMUTCD
• Outside built up areas• 400 ADT or less• Paved or unpaved
• Less extensive
MDOT Local Safety Initiative 57
Intersections
• Unsignalized• Improve sight distances• Control access points• Improve visibility of intersection• Verify choice of traffic control
MDOT Local Safety Initiative 58
Sufficient Sight Distance
MDOT Local Safety Initiative 59
Intersections
• Signalized• 12” signal lens and improved placement
• Appropriate Clearance Intervals
• Re-timing
• Add turn lane
• Add turn phase
MDOT Local Safety Initiative 60
Before a Signal Consider…
Improving visibility:
• Advance warning signs(with or without beacons)
• Relocating stop bars
• Flashing red beacon
• Roadway lighting
MDOT Local Safety Initiative 61
Before a Signal Consider…
Improving traffic operation:
• Additional lanes
• Revised geometrics
• Restricted turning movement
MDOT Local Safety Initiative 62

Ionia CountyRural, and growing…
MDOT Local Safety Initiative 66
Ionia Safety Efforts
• Developed a “road safety audit”• Team review of locations• Low cost fixes• Funding issues
• Working to define county warrants for various treatments
• Need rational basis treatments• Local Agency Programs (LAP) applications
• Crash review• Input: engineering, maintenance, management
MDOT Local Safety Initiative 67
Federal Local Safety Program (MDOT - LAP)
• Upgrading guardrail at structures• Intersection upgrade project
• township jog• Y to T reconstruction• Drain relocation• Guardrail upgrade
MDOT Local Safety Initiative 68
LSI - A Local Perspective
• Early involvement can be a benefit• Complacency is a killer ….
• Another pair of eyes
• Saves time – I would not be able to do this level of analysis
• Might be an opportunity• Provides some additional data in support of
safety project applications
MDOT Local Safety Initiative 69
In Depth look
• Patterns• Fatals• Intersections• Segments
MDOT Local Safety Initiative 70
Site Visits
• Some locations were a surprise• Provide an in depth look at systems• Another set of experts• Supporting data for garnering resources• Uniformity
MDOT Local Safety Initiative 71
“Cautious Enthusiasm”
• Maintenance issues• Warranted treatments• Level of long term commitments
MDOT Local Safety Initiative 72
Benefits
• Additional expertise• Identification of atypical problem locations• High risk
MDOT Local Safety Initiative 73
This is a Journey …
• This program could change how we do business
• Not an end in itself• Could be a way to fund some projects• Low cost solutions• Another way to identify problems
