The paper sets out the theoretical basis for transtep and describes case studies where it has been applied. Transtep is an inexpensive sketch planning model, which derives changes in travel patterns due to land-use or transportation system changes. It derives zonal trip generation rates and trip length distribution characteristics from zonal activity distribution and skims, before distributing trips to form a trip matrix. It is, therefore, suitable for impact evaluation. Further, one transtep module derives changes in zonal population density due to accessibility changes and, therefore has been used to predict population growth patterns in urban areas. Transtep graphically outputs contours showing zones of imbalance between employment and potential for employment derived as the probable trip-end density. /TRRL/
