Answer for Bus Driving Standards

Answered By: 
The Mayor

a) TfL do not analyse Driver Quality Monitoring reports at an individual route level as drivers generally work on a range of routes operated by their garage. The survey has been designed to assess driving standards by garage. Scores broken down by route are not statistically robust. If you are interested in Driver Quality Monitoring reports for a particular garage, TfL would be happy to supply them to you.b) Bus services generally serve several boroughs along their routes, and so a borough by borough breakdown is not available. c) Within the Monitoring, each aspect of the journey (for example: braking, smoothness of acceleration, closeness to kerb at bus stops) is coded as a `box type' and then aggregated as follows: Box Type Aggregate Weighting BOX 1 FULLY ACCEPTABLE 0 POINTS BOX 2 ACCEPTABLE WITH SOME DRIVING FAULTS 2 POINTS BOX 3 UNACCEPTABLE WITH SERIOUS FAULTS 20 POINTS BOX 4 UNACCEPTABLE WITH DANGEROUS FAULTS 50 POINTS

As an example, an assessment with 21 measures scoring Box 1, 1 measure scoring Box 2 and 1 measure scoring Box 3 would have an overall score of (21 x 0) + (1 x 2) + (1 x 20) = 22. A high score therefore reflects a high number of unacceptable results (Box 3s and particularly Box 4s).
