First, when we plan our routes, in order to be as efficient as possible, we maximize bus capacity utilization. Right now we try to put three to a seat. If you consider that the average seat is about 96 centimetres wide and we can seat three, we are concerned, especially with the snowsuit issue and trying to actually clip them in, that seating capacity might not be adequate.
Second, we also look at the time. We're trying to create runs where we are picking up students at their stops and delivering them to school in as short a time as possible, given traffic and other environmental conditions. The more runs we can put on a route, the more efficient that route will be. We may currently have triple routes, where we can service three schools. Because of the time it would take, for example, to attach belts and then pull over the bus to deal with students who detach their belts, that time element has to be built into the route design. We know that we won't be able to double or triple routes if we have that extra time element.
