Since we assume that bike libraries are set up to promote mass use of bicycles, in this section we will also assume that bike libraries have somewhat direct effects on public and environmental health.
Environmental benefits are extensively connected with the larger health benefits of cycling. In addition to direct health benefits to human-beings, it brings benefits for other forms of beings, for the ecology in general.
Bicycle use brings out health and environmental benefits on a set of levels:
As for the urgency in getting more cars off the roads, the external costs of motor-vehicle transport should be revisited.
One of the most dramatic external costs of this mode is the number of fatalities and serious injuries due to motor-vehicle accidents. According to the National Transportation Statistics of 2005, in only 10 year span between 1990 and 2000, more than 480,000 people died due to traffic accidents involving motor vehicles. During the same period, by comparison, the total number of deaths due to accidents involving mass transit and railroad modes was about 15,000 - about 31 times less than the highway figures. Moreover, every year about 3 million people get injured because of motor-vehicle traffic accidents (Table 2.1).
“Highways, cars, and trucks accounted for 95 percent of the nation’s transportation fatalities and 97 percent of the injuries. (...)Whereas highways were responsible for about 86 percent of all person trips, they accounted for 94 percent of the nation's transportation fatalities. Transit, on the other hand, accounted for nearly 4 percent of all person trips yet less than 1 percent of all transportation fatalities and 2 percent of injuries" (Gillham 119). As noted elsewhere on this website, in the meantime, “the monetary cost of U.S. motor vehicle accidents in 1986, for example, was estimated to be $74.2 billion….Motor vehicle fatalities for the period of 1977-88 exceed all U.S. battlefield fatalities in all wars from the revolutionary war through the Vietnam War” (Loeb et al. 2). Banister notes that on average traffic accidents cause 250,000 deaths and 10 million injuries each year worldwide (16).
Another direct burden that motor-vehicles put on the society yet fail to pay is the cost of deaths and illnesses due to air, water, and soil pollution from the exhaust gases.
