The vast scale of potential development in Baghdad, with a possible investment of US $12000 million between 1980 and 2000, demanded that the transportation planning had a large and reliable database. It was necessary for the database to cover land use and socio-economic data in addition to traffic information. Extensive surveys were carried out and the database was established on the computer system at the national computing centre. Twelve different surveys were carried out covering the complete range normally associated with studies of this sort. The surveys were very large: including 17000 home interviews, 30000 roadside interviews, 38000 public transport interviews, 8000 employment interviews, 4000 goods vehicle interviews. The scale of the surveys added to the many other problems associated with carrying out surveys in Baghdad and meant that the data collection and data processing phases occupied 18 months of the study in Iraq. Specific difficulties such as sample selection were associated with each of the surveys whilst others including quality control were general to all. The results from the various surveys showed that some had not produced returns consistent with the effort involved in conducting them. (Author/TRRL)
