A cost-effective method of collecting origin and destination data in urban areas is to pass simple prepaid postcard questionnaires to drivers at the roadside. However, if congestion is to be avoided, two supervisors equipped with two-way radios will be required at each survey station during peak hours. Based on experience with two surveys in Northampton it appears that an overall sample rate of about 25% can be expected, representing a response rate of about 40%. However, the response rate from heavy goods vehicle drivers may be disappointingly low. This might be overcome by allowing HGV questionnaires to double as raffle tickets, but no surveys where this has been tried have been discovered. (TRRL)
