Separate models were developed by trippurpose. The results indicate several statistically significant and intuitively reasonable effects ofland-use patterns. High residential densities and a good mixing of complementary land-uses areassociated with shorter trips. Larger establishments attract longer trips and the HBO trip lengthsdecrease with increased number of convenient-commercial land-use parcels in the neighborhood.The connectivity provided by the roadway network and the urban-form of the area (measured interms of number of intersections and cul-de-sacs) also affect trip lengths. In addition to the localland-use characteristics, the trip lengths also vary significantly by the location of theneighborhood with the region. All these results hold even after controlling for several trip andtraveler characteristics.Trip length models are applied within a regional, neighborhood and project context toestimate trip lengths of a hypothetical development. Two simplified tools are presented thatutilize the proposed models within an Excel and Geographical Information System environmentthat enable a user to estimate trip length as a metric of demand on the transportation networkfrom a proposed project
