Case Studies

A pilot of 4 SAM surveys has been undertaken in 2005 and again in 2008. The following summarises the modal shift, changes in trip rates and any travel plan measures that have been implemented at each of the pilot sites.

  The modal split data comparison between 2005 and 2008 for this site can be seen in the figure below.

The figure illustrates that the vehicle rates have fallen from 79.7% to 75.5%. All other modes have increased. The proportion of pedestrians rose from 17.7 to 19.2%, for public transport users from 1.2% to 2.5%, and for cyclists from 1.4% to 2.8%, effectively doubling the proportion for the last two categories.

  As can be seen in the table below, the vehicle trip rate calculated with TRICS shows a decrease from 15.460 in 2005 to 14.635 in 2008.

Year      Trip rate
2005 15.460
2008 14.635

The results from the comparison indicate that vehicle travel is decreasing and alternative modes are increasing, to be seen in the modal split as well as the trip rate calculations.

The following changes have occurred since the survey was undertaken in 2005:
  • The Park & Ride facility was replaced with a Park & Walk facility, with a single car park within walking distance of the site. However, before the re-survey, the situation had reverted back to Park & Ride, as the Park & Walk facility was being built on.
  • Motorcycle sheds have been installed in the period between the 2005 and 2008 surveys.
  • Whereas during 2005 the Travel Plan Co-ordinator was operating full time, in 2008 it was a part time responsibility. The original Travel Plan Co-ordinator had left, and the travel plan was put “on hold” for some time during
  • the interim period between the two surveys.
