The Cycle use section summarizes data regarding how many ride in various countries, etc. The Factors section recounts terrain, weather, traffic volumes, speed, etc. This is the case even in places with extensive special facilities for cyclists. Chapter 2 is history since WWII, mainly European. It recounts the growth of motor vehicle use, effects on cities, the 70's energy crises, and efforts to shift back to public transport and bicycles.
Several pages discuss the European experience with bike lanes and paths.
It enumerates the various problems they have, including those at junctions and intersections, effect on speed and travel time, attraction of careless riders to paths, width and visibility, conflicts with pedestrians, turns, delays at multiple phase lights, poor maintenance, etc. Chapter 3 summarizes planning methods in towns and cities. The traffic calming reduces the motor vehicle speed, and the speed of collision between motor vehicles and bicycles, hence reducing the severity of injuries. Chapter 4 covers interfacing bicycle and public transportation, mostly trains and buses. It covers both parking the bike at the station to ride the transport, and bringing the bike along on the transport.
