? Higher capacity buses are used in a variety of applications, as was discussed in chapter two, but certain patterns are apparent, depending on the type of HC bus being considered: • Articulated buses are predominantly deployed in allday heavy-demand trunk (or BRT)

This finding is not surprising because of the shorter wheelbase of the front section of the articulated bus. However, more than half of respondents perceived that the performance of articulated buses was less than that of standard 40-ft buses, in three areas in particular: • Fuel economy, • Grade climbing, and • Acceleration.

when compared with the diesel control fleet. These findings, in combination with the findings in chapter four, indicate that hybrid propulsion technologies offer a promising approach to overcoming some of the concerns expressed with respect to articulated buses, in particular, with respect to the issues of acceleration and fuel economy in frequent stop-and-go types of operations.

This modification would be applicable for any bus with a lift or ramp in a location other than the first door. The length of articulated buses may lead to a number of potential modifications to stops in terms of removed parking spots or lengthened concrete pads (depending on whether the bus has a third door)

OC Transpo in Ottawa is one agency that traditionally has had an aggressive objective of using the scheduling system to minimize peak bus requirements through the use of interlining, and this applies as well to their articulated buses (J. Koffman, OC Transpo, personal communication, Feb.

Such a process requires considerable access to data, sophisticated scheduling tools, staff expertise, and management oversight, but enables an optimization process that makes best use of limited resources, such as HC buses and operators, and results in higher efficiency and revenue-cost performance. Reducing Dwell Time The use of HC buses increases individual vehicle capacity, which can be used to increase overall route capacity, expressed in passengers per hour.
