Summary of modes

So what does all that mean? To compare these modes side by side, consider what it would take to move America’s 140 million person workforce the average trip distance for each mode. 10 miles in traffic, 5 miles for transit, 1.3 miles walking and 3 miles biking. The cost to build those routes anew to carry all those people that short distance would be $875 billion for traffic, $350 billion (40% of traffic) for transit, less than 1% for walkways, and under 2% for bikeways.40%. Of course, we already have all the roads we need built, so how doe the cost of maintenance and operations of vehicles compare? Transit ids the only mode where an agency has to operate the vehicles. For the other three modes, the purchase, operation and steering of vehicles is our own responsibility. The cost of maintenance by the government or agency plus the cost of operation of vehicles on the roads by either the agency or the public is for the workforce to make same short trips is $258 billion a year for traffic, 56% of that for transit, less than 1% of that for walking, and 9% of that for biking. The cost to build enough route ways to carry all those people those short distances would be $875 billion for traffic, 40% of that for transit, less than 1% for walking and under 2% for biking.
The energy consumed in that workforce average trip is 4.7 trillion BTU for traffic, 24% of that for transit, and 2% of that for walking or biking.
The amount of real estate needed for the workforce to move and park their vehicles (if any would be 8,788 square miles for traffic (an area the size of New Jersey), 9% (803) of that for transit, 1% (Washington, DC) of that for walking and 10% (854) of that for biking.
Safety is the only field where traffic surpasses biking and walking. The chances of being killed in traffic are 0.8 fatalities per 100 million miles, 38% of that for transit, but 19 times that for walking and 13 times that for biking. Per hour, your chance of dying in traffic is 2.7 deaths per billion hours, 12% of that in transit, 160% of that on foot and 400% of that on bike. Of course, safety for pedestrians and cyclists would be much better if fewer cars, trucks and SUVs there to crush them.
