Data

Bus Accessibility


Description

The Scottish Access to Bus Indicator (SABI) gives a score for the accessibility of bus services in each data zone and provides an objective measure of accessibility to public transport by bus in Scotland.

The indicator provides separate scores for weekday and weekend services. The output areas are aggregated to data zones using a population weighted average. The datazones are then ordered by quintile and decile, from least to most accessible.

The annual report can be accessed at the Transport Scotland website.

Data quality

Completeness

Tables and maps of the Scottish Access to Bus indicator are published in the annual report: Transport and Travel in Scotland.

Uniqueness

Not assessed

Consistency

Due to changes in services covered by the Traveline National Dataset, comparisons between years should be made with caution.

Timeliness

This dataset will be updated every 2 years, in the autumn.

Validity

Transport and travel statistics are used by a wide range of interested parties, such as:

* The Scottish Parliament and the Scottish Government (including Transport Scotland)
* Local authorities
* Regional Transport Partnerships
* Police Scotland
* Other public sector bodies (e.g. Scottish Enterprise and HIE, Cycling Scotland)
* Transport companies and their representative organisations
* Students, academics and other researchers
* Transport consultancies
* Other bodies with an interest in transport matters, such as the Chartered Institute of Logistics and Transport, the Scottish Transport Studies Group, SUSTRANS, the Institute of Road Safety Officers, the Royal Society for the Prevention of Accidents and other bodies concerned with road safety
* Politicians and members of the public.

They are used for a wide range of purposes including:

* Informing the general public's choices, e.g. lifestyle choices around road safety
* Government decision making through policy making and policy monitoring
* Resource allocation
* Informing public marketing campaigns e.g. road safety
* Supporting third sector activity e.g. lobbying and funding applications
* Facilitating academic research.

Accuracy

This data is based upon the Traveline National Dataset. It is possible that some bus services may not have not been included.

Quality management

The analysis was based on Traveline data, which was used to find all bus stops within a 400 meter walking distance, by path or road, of each 2011 Census Output Area Centroid in Scotland. For each centroid, the total frequency of buses per hour for each bus stop within 400 meter was summed. This resulted in a total average number of buses per hour accessible within 400 meter of each output area centroid, on both weekdays and at the weekend. Transport Scotland chose the 400 meter distance to walk to a bus stop, in line with DfT work and wider public transport planning guidance.
