Long-term council community plan (regional)

Given what was learnt from the PTAL assessment, new indicators for how well public transport was supplied were considered useful. These new measures were expected to provide a clear line of sight between the management and the measurement of public transport.

The current indicator relating to public transport was:

Percentage of the urban population in Greater Christchurch and Timaru within 400m of a bus route.

Problems with the above indicator included the following:

·         The 400m was measured as the ‘crow flies’ and therefore did not reflect the fine-grained nature of walking networks.

·         The indicator only measured access to bus routes, whereas in reality access to the public transport network could only be made at the bus stops.

·         The indicator did not take into account the frequency of bus services or where the bus was going to.

Therefore, the current indicator was less than ideal.

An updated indicator was developed that included the percentage of households:

·         in Greater Christchurch and Timaru within 500m walking distance of a bus route

·         in urban Greater Christchurch with access to two or more key activity centres by public passenger transport services within 30 minutes total travel time.

The first measure has remained a mobility measurement. The second is a true access measure and quantifies the opportunity provided by the public transport network both in terms of network supply and a basic geodemographic measure.
