A route is a linear feature that has a measurement system (for example, distance or time) and a unique identifier. Routes are stored in a route feature class (standalone feature class or in a feature dataset). The vertices of a route contain the x and y coordinates and a measure value or m value. Measure units are independent of map units. Measure values do not have to begin at zero and should be increased in the same direction.
In this section, you will create a route feature class that will store three simple routes that represent three different bus lines from your town: bus 133, bus 79, and bus 135. Your routes will be created from scratch using the Trace tool.
