In order to model the possible effects of rescheduling the work journey on city centre peak period traffic congestion, it was necessary to obtain information about the current employment position in the city centre, and about traffic conditions in the peak period. To this end, a series of surveys were designed and implemented to collect information from a stratified sample of centrally located employers; a sample of their employees; and about traffic conditions between the hours of 07.30 and 09.30 along selected routes leading into the city centre.
Problems in running the surveys were encountered and overcome, and the resulting information covered:
- Employee numbers, their permitted work hours, and the type of schedule worked per employer.
- The Standard Industrial Classification (SIC) of each employer.
- Car parking facilities provided by employer.
- Bus facilities provided by employer.
- Origin of employees' journey to work.
- Mode(s) used in employees' journey to work.
- Employees' actual arrival at and start work times, together with departure from work time, for the week preceeding the survey.
- Personal characteristics of employees.
- Structure of employees' households.
- Journey times and traffic flows along selected corridors.
The data thus collected was used to provide a base situation against which modelled alternative work hour strategies could be tested.
