Quality of Service (QoS) Standards for Basic Bus Services

The QoS Standards have two categories:

Operating Performance Standards (OPS) which measure minimum daily or monthly operational deliverables, either at the bus network or route levels. They cover the aspects of bus reliability, loading and safety; and

Service Provision Standards (SPS) which measure overall bus route planning and provision of services. They cover the aspects of service availability, integration and information.

1.3  Bus breakdown rate on all bus services  Less than 1.5% monthly.
2.1  Bus loading during weekday peak periods on each bus service Not exceeding 95% daily.
