Bus and strategic freight reliability overview
Summary of indicator
| Indicator Name | Bus and strategic freight reliability |
| Indicator Type | Supplementary |
| User Outcome | Reliable transport |
Objective
To measure the level of consistency of transport services for bus and strategic freight related trips.
Application guidance
Places do not exist in isolation from each other, and people within them form part of a wider community across the town, city or region. Public transport provides equitable and efficient access to and from more distant places, and deliveries and servicing are essential to create vibrant places. Both modes should be provided at the appropriate priority to their frequency and service type to enable connected and reliable journeys.
This indicator will support practitioners to understand the consistency of travel times across different days and/or times of day. Based on the outcome of the assessment, practitioners can determine whether improvements could be made to address poor performance.
Practitioners can use the planning time per kilometre metric to measure the total travel time that a traveller needs to allow to ensure that they arrive on time most of the time.
Practitioners can use the buffer time per kilometre metric to measure the additional time that a traveller needs to allow for unexpected delays to ensure that they arrive at their destination on time and is a measure of variability.
Practitioners can use the typical delay time per kilometre metric to measure the average variation in travel time from the free flow travel time and reflects traffic efficiency, such as the level of traffic congestion.
