. .:..~ - : <br />For the purposes of a contract, it is assumed.fewer than 12 alternatives <br />- (different street configurations) and 40 computer assignments (different <br />speeds, mode split assumptions, or land use scenarios) are included in <br />this project. <br />F. Transit and Alternative Modes Analysis <br />Analyze present and potential use of transit and alternative modes in <br />the~corridors. Some analysis probably needs to occur in both the re- <br />gional and site specific modeling phases, because the Ferry Street <br />Bridge corridor has a relatively high potential for transit and alterna- <br />tive modes. Tasks would include an analysis of 1980 Census data in the <br />corridor, existing mode split, and sensitivity analysis. The sensitivi- <br />ty analysis would focus on determining the impact of differing assump- <br />tions on the design hour volumes. <br />G. Geographic Information System Tie-In/Computer Mapping <br />Enhance the computer mapping capabilities of the Geographic Information <br />System for the Ferry Street Bridge area and for the new zone and node <br />link systems in the immediate vicinity. (A project is in progress which <br />will allow the outputs of the UTPS modeling to be mapped by computer <br />with the Geographic Information System. The current project is designed <br />for regional mapping and includes only the streets included in <br />TransPlan.) Expanding on current work, this task would would enhance <br />the graphic representations of existing streets and alternatives for the <br />Ferry Street Bridge area. This task would allow graphic output of <br />traffic volumes in addition to tabular output. Graphic output could be <br />used for public presentations and for publication. <br />III. TIMEFRAME <br />A"fast track" schedule incorporating the above-listed tasks, assuming a <br />go-ahead on the project by 3/1/89 would have the following completion <br />dates: <br />3/15/89 Refine TAZ <br />4/15/89 Update Base Year Dwelling Unit & Employment data <br />4/15/89 Refine Node-Link Systems <br />5/15/89 Update Design Year Dwelling Unit & Employment Forecasts <br />5/15/89 Calibrate Peak Hour Model for base year <br />5/15/89 Complete present use analysis of transit and alternative modes <br />6/15/89 Be prepared to commence "regional" modeling phase of analysis <br />12/1/89 Complete modeling <br />
