MDOT Transportation Enhancements

Sunday, March 7th, 2010

First the good news. MDOT recently made the following Transportation Enhancement (TE) awards that should improve bicycling in Metro Detroit.

From MDOT’s press release:

Macomb County

The city of Utica will construct a nonmotorized bridge over the Clinton River to provide accessibility and connectivity to the city of Utica’s portion of the bike trail that will connect the Huron Clinton Metroparks at Metro Beach and Stoney Creek. The project is part of the Macomb County Bike/Hike Master Plan and will allow bicyclists to connect to the Macomb Orchard Trail as well as the Clinton River Trail in Oakland County. The project cost is $452,525, including $303,192 in federal TE funds and $149,333 in matching funds from the city.

Macomb, Oakland, Wayne counties

SMART, in coordination with its community partners, will purchase and install bike racks at several locations in Wayne, Oakland and Macomb counties. The intent is to provide communities with secure bike racks at locations away from bus routes for the convenience of SMART riders who also ride bikes. The project cost is $20,016, including $16,013 in federal TE funds and $4,003 in matching funds from SMART.

Clawson is also getting bike racks installed along 14 Mile Road. Unfortunately they only seem willing to make mild improvements to walkability and even milder ones for bike-ability. Their conceptual plans for their Main Street road diet included bike lanes. Their final plans and implementation did not.

MDOT Five-year plan

MDOT recently released their five-year spending plan. With reduced revenue from people driving less, Michigan cannot provide the full 20% match for federal transportation funding.

This does affect the Transportation Enhancements program. Normally MDOT would provide $12 million in match for TE projects on their roads. That may be reduced to $1 million per year, which means MDOT will undertake fewer TE projects like paved shoulders, bike lanes, and streetscaping on MDOT state trunklines.

However, it also means that local governments will received more TE funding since they provide the match and not MDOT.

It’s also worth highlight this language within MDOT’s plan. This provides useful quote for cycling advocates in Michigan.

Pedestrian and bicycle transportation are on the rise due to increased fuel costs. Injury and fatality statistics are humbling reminders of the importance to design and build safe facilities for multiple modes of transportation and of the importance of education and enforcement.

It may be surprising to some that in Michigan, one pedestrian is injured every three hours and 59 minutes and one bicyclist is injured every five hours and 13 minutes.

In addition, in 2006, 17.9 percent of the 1,002 traffic fatalities in Michigan were bicyclists or pedestrians, whereas nationally, 11.6 percent of the 42,642 traffic fatalities were bicyclists or pedestrians. A reduced [Transportation Enhancements] program would severely jeopardize MDOT’s ability to provide safer pedestrian and bicycle facilities.

This does raise one question.

If 17.9% of road fatalities are non-motorized users, why did the Michigan Office of Highway Safety Planning only allocate 0.36% for non-motorized safety under the State and Community Highway Safety Grant Program in 2009?

Pedestrian and bicycle safety data analysis

Tuesday, July 21st, 2009

If you spend much time perusing the available safety publications for Michigan, it becomes fairly evident that not much serious effort is put into bicycle and pedestrian analysis.

SEMCOG

One example is SEMCOG’s Crash Facts report where more analysis and pages are devoted to vehicle-deer crashes than either pedestrian crashes or bicycle crashes. This is despite the fact that deer caused just one driver fatality in 2007. There were 65 pedestrian fatalities and 7 bicyclist fatalities in 2007.

For 2008, SEMCOG issued a cheery press release because overall fatalities and crashes were down.

“We are extremely happy to report this continuing decline in traffic crashes in Southeast Michigan,” notes SEMCOG Executive Director Paul Tait.

SEMCOG failed to note that both bicycle and pedestrian fatalities were up. In fact, 18% of all fatalities were pedestrians and bicyclists in 2007. In 2008 that pecentage jumped to 24%.

It seems the “analysis” is simply plugging this year’s numbers into the same old template.

A worthwhile analysis would look at trends within the region and where within the roadway these crashes are occuring.

Do we really need SEMCOG telling us that “bicycle crashes were more common in warmer months…likely due to the difficulties of bicycling in snowy or icy conditions?” They’ve been recycling this same text since 2002.

MDOT

To their credit, MDOT has supported some pedestrian safety studies within the city of Detroit. The city of Detroit’s Traffic Engineering department is has applied for safety funding to make improvements that should reduced pedestrian crashes.

GTSAC

Also, the Governor’s Traffic Safety Advisory Council includes some good analysis within the Michigan Pedestrian and Bicycle Safety Action Plan.

OHSP

One interesting analysis from the Office of Highway Safety Planning (OHSP) compares 2007 bicycle crash injury severity for helmeted and non-helmeted riders. We’ve rebuilt their data table as follows:

2007 Bicycle Crashes Total crashes Fatal or serious injury Minor or no injury
With helmet 177 18% 46%
No helmet 795 10% 51%

(Note that it is unreported whether helmets were worn in a little over half of the crashes.)

Among bicyclists wearing helmets in crashes, a significantly higher percentage suffered serious injury or death when compared those without helmets. One would expect the helmeted riders would have a reduced percentage of serious injury or death.

Can this be explained by risk compensation or demographics?

Nonetheless, the OSHP apparently didn’t do much analysis since they’ve cut-and-pasted a quote that’s unsupported by their own data: “Making the use of helmets the single most effective countermeasure available to reduce head injuries and fatalities resulting from bicycle crashes.”

And just to be sure that 2007 wasn’t simply a unique year, we looked at this data back to 2004. For every year, bicyclists wearing helmets in crashes suffered an equal or greater percentage of serious injury or death.

For what it’s worth, there is not a trend towards increased helmet use among those involved in reported bicyclist accidents within Michigan.
