Flexible carpooling is built up route by route. Each route has an equivalent return route.
A flexible carpool route starts at a 'flexible carpool park'. As mentioned previously, cars are parked in areas according to the destination, in a special design to make it easier to form fuller cars.
The flexible carpool park is located where the traffic converges, in the suburbs before the on-ramps for the freeway. It might be inside the clover leaf, or even over top of the road.
The route goes to a destination that's close to where lots of people work, or perhaps to a transit station. At the destination there is a drop-off point.
The return route starts at a pick-up point near to the drop-off point, and ends back at the flexible carpool park.
Routes are chosen based on the number of single occupant vehicles (SOVs) that go past a convergence point and on to the destination. The routes with the most SOVs are likely the best routes to establish a flexible carpooling route.
Potential routes are identified in two key ways:
1. Traffic engineers carry out analysis of the traffic flows and find potential routes, or 2. People who would like to use flexible carpooling register on a website and indicate support for a route that has already been proposed, or propose a new route that they believe will work.
It takes time to build support for a route, and to then convince the transportation authorities to establish the route. But it is worth it in the long run as everyone will save fuel, emissions, and time.
