Abstract

Using overall modal split figures to monitor the effectiveness of Travel Plans can often produce discouraging and misleading results. This paper describes examples of how GIS mapping has been usedvery simply to show how effective Travel Plans have been in creating mode shift in localities where there is the greatest potential for change. The approach has also been found useful in planning Travel Plan measures that are likely to have the greatest impact, and adapting Plans after initial monitoring.

Home locations are geocoded and overlayed over maps showing areas that are judged accessible by different modes. Analysis of observed modal split within these areas can show where there has been significant change, where there is the greatest scope for change, and where, for example, new bus routes would find most potential patronage. GIS allows a much greater degree of detail than zoning data.

The paper uses examples of analysis from Oxford where a parking exclusion zone combined with improved bus services has shown how modal shift from different areas has been to differing modes (walk, cycle or bus) depending on ease of access by these modes. The aim of the paper is to show the results of using simple analysis rather than to show developments in GIS methodologies.
