WORT{ ITEMS The work items that are proposed here can be summarized as follows: I. Revised Short -Ran a Anal sis The interim report produced for the Five -City Traffic Analysis contains considerable information with respect to short-range improvement needs. Questions regarding feasibility of some of the projects will be resolved, and the program will be updated to reflect the seven-year time frame. The steps that will be undertaken in this regard are as follows: 1. Prepare new land use database (1999; 2. Prepare new traffic forecasts 3. Revise improvement program It is anticipated that item 3 will involve numerous iterations with respect to traffic model data, and will require considerable input from the project team. The product will be a revised version of the short-range improvement program. 2. ImRroyement Costs In this work item, costs will be assembled for the improvements identified in work item i above. These cost estimates will be prepared by each jurisdiction, and reviewed by AFA for reasonableness. 3. Nexus Analysis This step in.. the analysis will be a r exus evaluation of the improvement costs and land use growth in the study area. The nexus procedure will relate the costs of the improvements at each individual location to the growth in land use (existing to 1999). The result will be a set of costs per tripend specified by individual areas within the overall study area. In carrying out this analysis, a set of sub -areas will first be defined, and the growth in land use in each sub -area will be estimated. Various nexus formulations will then be analyzed, taking into consideration participating development, existing fee programs, etc. While at this stage it is not intended that the nexus results should be directly converted into a fee program, the results will Four -City Traffic Study 2 Austin -Foust Associates, Inc.
