5MDOT Strategic Plan
- Goal Enhance and continue to improve safety
within our transportation systems and work
place. - Objective Continue to develop partnerships to
reduce fatal crash and injury rates through a
combination of education, infrastructure
improvements, enforcement and technology.

- Trunkline Safety Program - 70M/Year
- 3M/Year Non-Freeway Rumble Strips
- 14M/Rear Cable Median Barrier
- Local Safety Program - 15.2M/Year
- Local Safety Program - 12.1M
- High Risk Rural Roads - 3.1M
- Dedicated Safety Funding - 85.2M/Year
10Rural Highway Safety Issues
- Nationally about 60 of fatalities are rural
- Majority of rural crashes are on two-lane roads
half are off the state highway systems - Nationally, poor data on the local system
- Inadequate roadways/Random crashes
- Emergency Medical System limitations
- Lack of enforcement personnel
11High Safety Payoff / Problem Areas
- Alcohol 40 of Fatals
- Speed 30 of Fatals
- Belts 50 of Fatals unbelted
- Motorcycles 10 of Fatals
double digit growth - Large Truck involved 12 of Fatals
- Highway Intersections 25 of Fatals
- Highway Lane Departure 40 - 50 of Fatals
12 Michigan Fatal Crashes Trunkline vs. Local
13 Trunkline Program
14Lane Departure Focus
- Nationally accounts for 40 50 percent of all
fatalities - Many factors involved
- Drowsy driving
- Distracted driving (cell phones)
- Weather issues (ice, snow, poor visibility)
- Driver confusion (signing, pavement)
15 Michigan Single Vehicle Lane Departure Fatal
Crashes
16Lane Departure Focus
- Many countermeasures
- proven effective
- Rumble strips (edge and center line)
- Cable Barrier System
- Quality Pavement Markings
- Vehicle Infrastructure Integration Virtual
rumble strips based on global positioning
satellite technology
17 Michigan Experience
- Non-Freeway rumble strips (edge and
centerline) - 2008, 2009, 2010 - 3 million per year
- - Anticipate 50 reduction in K and A crashes
- (Targeting 16 Ks and 62 As per year)
18 Rumble Strips Keep Drivers in Their Lane
- Milled Freeway Rumbles
- Standard
- Since 1998
- Proven
- Effective

19 Non-Freeway System
- Statewide Implementation
- Centerline Rumbles
- Shoulder Rumbles
- 3 Year Funding Effort
- 2008 2010
- 3 M per Year
- Estimated 50 Severe Crash Reduction
20Cable Median Barrier Catch Them When They Leave
- Low Cost Median Protection
- 95 Effective in Capturing Lane Departure
Vehicles
21Michigan Experience
- Cable Median Barrier
- - 2008, 2009, 2010- 14 million per year
- - 95 effective in reducing median crossovers
- - Estimated time of return is only 2.9 years!
- (Targeting 13 Ks and 52 As per year over 340
miles)
22 Freeway Analysis

25 Michigan Demographics
- Over the Age of 65
- In 2000 - 12 of Population
- By 2030 Expected Over 20 of Population
- 17 are Non-Drivers
- 50 of Non-Drivers Stay Home and Do Not
- Access Community Resources, in Part Because
- They Have No Transportation Options

31Signals DesignBox Span Installation
- MDOTs first choice for signal design October
2006 - Initial crash information indicates improvement
on right angle type crashes (Based on Minimal
Crash Information to date). - Indications are that box span installations
reduce red light running - Drivers hesitant to cross intersection on red
indication since they can see the indication
while they are in the intersection - Slight increase in rear end type crashes that
could be linked to drivers hesitant to run a red
light (stopping when others behind would keep
going) - Box spans place signal heads in better cone of
vision for all drivers but especially helpful for
elderly mobility (angle to see heads is less
severe) - Conflicts with overhead utilities can lead to
difficult installations
32Box Span InstallationOne Signal Face per Lane
Centered over each lane
33Pavement Markings
- 6 inch edge lines, 12 inch gore markings
- Enhanced quality inlaid centerline markings
- Rumble strips centerline and shoulder
- Paint in shoulder rumble strips
Wet, night time reflectivity
34Local Safety Initiative3 Pronged Approach
- Assist Local Agencies and Address Safety Concerns
through - Crash Analysis Field Reviews
- Improving RoadSoft Safety Module
- Improving RoadSoft Safety Module
35 To Date
- 44 Counties (1 Township)
- 13 Cities/Villages
- 3 Projects
- Spreading the Safety Word
- Major Improvements in RoadSoft Safety Module
36Local Agency Safety Initiative
- Five staff positions assigned
- (3 dedicated full time)
- Free engineering and safety audits available to
local agencies - Working through CRAM and MML
- Low cost safety improvements
37High Risk Rural Road (HRRR) Program
- New program with the Federal Highway
BillSAFTEA-LU - 3,190,000 of Federal funds available (2009
program) - 100 of funds allocated to Local Roadways (0
allocated to state trunk lines) - Funding 90 Federal / 10 Local and some
qualifying projects at 100 Federal Funds
38High Risk Rural Road(HRRR) Program cont.
- Maximum 400,000 Federal available per project
- Roadway is required to be classified as Rural
Local, Rural Minor Collector, or Rural Major
Collector - Roadway needs to have had 1 A or K crash
within last 5 years
39Local Agency Safety (STH) Program
- 12,150,000 of Federal funds available (2009
program) - Funding 80 Federal / 20 Local
- Maximum 400,000 Federal available per project
40Funding Targets
- 10,000,000 for projects correcting Type A
K crashes - 1,000,000 for guardrail upgrades and clear zone
improvements - 200,000 for shoulder and centerline rumble
strips projects
415 Report Projects
- P.E. Eligible for STH funding (up to 10 of
construction costs) - Must be on 2006 or 2007 lists

54Local Safety Program ResultsBefore and After
Study
- The fifty-seven projects constructed over the two
years resulted in an annual average crash
reduction of 20.0 (835.7 before and 668.5
after). This is a reduction of approximately
2.9 crashes per location per year. - Total annual average injuries for the fifty-seven
project group decreased from 266.3 to 212.3
(20.3 reduction), slightly less than 1 injury
per location per year.
