Addenbrookes Hospital Multimodal Surveys

Working on behalf of the NHS Trust.

Surveys included; cyclist interviews, multiple cycle and pedestrian counts, manual turning counts, car park accumulation across the site, bus frequency and usage at the hospital terminus and ANPR surveys.

Aims of the survey; Addenbrookes Trust needed to identify on an on-going basis how successful their attempts have been to encourage fewer car trips to the hospital by staff, patients and visitors.

For some years ATR have worked with the Addenbrookes Trust to demonstrate their attempts to minimise the impact of hospital traffic on the local roads, by showing that through encouraging bus usage and car-sharing, and improving cycle facilities, the number of car journeys to and from the hospital have decreased on a year on year basis.

Through careful consideration and deliberation, ATR and the hospital trust designed a series of surveys calculated to show the impact of the measures implemented. Turning counts were undertaken at each of the hospital entrances, while cycle and pedestrian counts were carried out at these points, and all other pedestrian accesses. Cyclists were also asked to provide details of their departure point to create a database from which it could be determined how far staff and visitors were willing to travel to the site by bicycle.

Passengers alighting and boarding buses at the hospital terminus were also monitored to show any changes in bus usage.

Each of the hospitals 9 car parks were monitored throughout the day to calculate the degree of saturation; while occupancy of each of the vehicles parking was also scrutinised upon entry to gain an understanding of the degree of success of the Trust’s attempts to encourage car sharing.

ANPR surveys were carried out on each of the hospitals entrances and exits in order to separate ‘rat-running’ traffic from genuine hospital traffic.

Over the period that ATR have been carrying out these multi-modal studies, we have worked with the Trust to modify the brief over the years to adapt the survey scope to incoporate the changing traffic patterns that affect trips to the site. Certain surveys have been omitted, such as the cyclist interviews; for which sufficient data has been collected, and further surveys and sites have been added; such as occupancy of staff car parks, to reflect the changes in traffic flow to the site.

Each year’s survey is has been presented in tabulated spread sheets, within the 20 day time frame mutually agreed.
