The ratio of annual vehicle km to the maximum number of vehicles scheduled for peak-period service is an indicator of the relative efficiency of resource (vehicle fleet) utilization by management. The efficiency of resource utilization influences resource requirements; in other words, for a given level of peak-period service, a larger number of vehicle-km per “peak bus” implies a smaller number of buses required to operate this service. As above, the underlying “causal factors” reflect service-planning issues.

 

The authors calculated the number of annual “Urban Service Bus km” and “Revenue km” per “Maximum Peak Scheduled Vehicle;” the indicators reported by OC Transpo are based on total km, revenue km, and active fleet size. Although annual km per peak bus increased substantially during 1972-1982, no significant change was associated with opening of successive transitway segments. Adjustment for relative vehicle size (i.e.. increased use of articulated buses from 1982) would reveal some degree of increase.

 

Trends - Annual Urban Service km and Annual Revenue km per Maximum Peak Scheduled Vehicle

 

Prior to the start of transitway construction, OC Transpo anticipated that increases in annual km per vehicle would permit operation of service with a smaller fleet size. This, as above, was based on alternatives analysis results during early planning stages - and might be described today as “another theory that was not tested.”
