Bicycle transportation planning and engineering

Bicycle transportation planning and engineering is all about making it easier and safer for people to ride bicycles. This includes making it easier for them to get from one place to another, by providing paths and trails for them to ride on, and also making it safer for them to ride, by designing roads and intersections with special markers and signs so cyclists know where to go and how to avoid getting hit by cars. Usually, cities and towns will hire special people to plan and design these paths, roads, and intersections, to make sure that everything is set up as safely and smoothly as possible for cyclists.
