RIDERSHIP OR COVERAGE
Within a fixed budget, a transit agency must make a choice in how to distribute its service. The example below shows how this works for a fictional town with 18 buses where all the dots represent people and jobs in the town.
On the left, the High Ridership Scenario, bus service is concentrated into a few frequent routes, only in the busiest areas. Waits are short and trips are faster in places with the most residents and businesses. However, less-populated areas may have no service at all.
On the right, the High Coverage Scenario, most streets have some minimal bus service, even in places with very few people. Everyone is a short walk from a bus stop, but waits are long and trips are slow.
