Youth (ages 5-15) involvement in bicycle crashes in Michigan is higher than national statistics: 32.4% compared to 26.8%.That means nearly one-third of all young people in Michigan are involved in a bicycle crash and one-forth of those (25.3%) are fatal/serious.Pretty interesting. Here are some of the proposed solutions for improving bicycle and pedestrian safety:
In all other age classifications, Michigan’s rate is lower than the national data, except for those 65-74 years old.
Men are involved in 81% of all fatal bicycle crashes in Michigan. Bicycle crash locations are nearly evening spilt between intersections and non-intersections (49% to 51%).
Despite the perceived safety of a signalized intersection, almost half of all fatal and serious injury bicycle accidents (48.9%) took place at signalized intersections.
More than half of all fatal/serious injury bicycle accidents took place on two-lane roads (56.6%), followed by five-lane (13.8%); four-lane (12.9%) and three-lane (9.7%).
Together, 25 and 30 mph streets (neighborhood and downtown streets) accounted for 75.5% of all bicycle crashes, but the majority of fatal bicycle crashes took place on streets/roads with a speed limit of 45 mph or greater even though they comprised only 19% of the crashes.
Between 3:00 p.m. and 6:00 p.m., 27.2% of fatal and serious bicycle crashes took place, followed by 6:00 p.m. to 9:00 p.m. (21.8%); and 12:00 p.m. to 3:00 p.m. (18.5%).
The day of the week made almost no difference for fatal and serious injury bicycle crashes in the 2005-2010 time frame, ranging between a low of 151 on Sundays to a high of 220 on Wednesdays. The average is 192 and the weekday average is 205.2.
More than two-thirds (71.2%) of all fatal and serious injury bicycle accidents took place during daylight hours and 89% where when the pavement was dry.
Alcohol was not involved for the motorist or bicyclist in 70% of the fatal and serious injury crashes.
Roundabouts showed an overall decrease in all types of crashes by 35%, injury crashes by 76% and fatal crashes by 89%. They also are one of the most expense improvements, costing between $250,000 and $500,000.So those sharrows do something after all.
Road diets reduced all crash types anywhere from 14% to 49%.
Raised medians reduce all crashes by 40%, and by as much as 69% at unsignalized intersections.
Bike lanes can reduce bicycle crashes by 50% and are most appropriate on streets with average daily traffic volumes exceeding 3,000 and posted speeds between 25 and 35 mph.
Buffered bike lanes are preferable on roadways with speed limits exceeding 35 mph.
Shared lane marking (sharrows) were found to increase bicyclist visibility to motorists, reduce the occurrence of wrong-way riding, and riding on sidewalks.
Green, high-visibility bike lanes will be added to the next version of the Manual of Uniform Traffic Control Devices (MUTCD). Where tested, these have been shown to improve safety through a variety of measurements.
