Case Studies

Glaxo Smithkline, Weybridge
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 comparison for this site between 2005 and 2008 can be seen below.Glaxo Smithkline, Weybridge
The figure shows that the vehicle rates decreased slightly, from 82.8% to 80.4%. Pedestrian rates rose by 3%, from 3.7% to 6.7%. Public transport users fell slightly from 11.4% to 10.8% and cyclists remain consistent at 2.1%.


In terms of total vehicles and people, these figures fell from 691 to 582 for vehicles and from 847 to 770 for people, as seen in the figure below.

  As can be seen in the table below, the vehicle trip rate calculated with TRICS shows a decrease from 6.712 in 2005 to 5.651 in 2008.

2005 6.712
2008 5.561

The results of the comparison between the two years illustrate that vehicle travel is decreasing, to be seen in both the proportion of vehicle travel and the trip rate generation.

The following changes have occurred since the survey was undertaken in 2005:

The number of public bus services has more than halved since the 2005 survey. For the 0700-1900 period (weekdays), there are now a total of 22 services, as opposed to the earlier total of 48. This is down to a particular service being discontinued. At the time of the 2005 survey, there was off-site parking available for employees at the nearby Parkland College (spaces leased by GSK). These spaces are no longer in use, as the number of on-site spaces are considered to be adequate. However, the lease on the college spaces continues to be paid by GSK, in case of further company expansion. Note that the shuttle service between GSK and the off-site spaces has been discontinued because of this. Another consequence of this change is that the on-site number plate recognition system is now only used for security purposes, and not for spotting vehicles that should have been using the off-site parking and shuttle service.

There has been an increase in the cost of staff season ticket loans since the 2005 survey.
