Exhibit A <br /> Task 02000—Transportation Modelin& <br /> Through previous planning studies in the Decatur area,the AECOM team has developed two <br /> transportation models that could be utilized for the MIP Transportation Plan. These models,and their <br /> potential application to the MIP study,are described in the following: <br /> • Regional Travel Demand Model—AECOM recently updated the regional travel demand <br /> forecasting model as part of the DUATS 2040 Long Range Transportation Plan (LRTP). The model <br /> includes a base year of 2010 and a future year of 2040. The regional travel demand model could <br /> be used for the MIP study to evaluate potential roadway capacity improvements (i.e., new <br /> roadway connections,or widening of existing roadways). If necessary,the project team can <br /> modify the future year(2040)socioeconomic data to reflect potential employment increases <br /> within the region. This could be done to reflect possible additional economic development <br /> activity related to the MIP. <br /> • Rail Traffic Control(RTC)Model—As part of the DATES project,AECOM developed a RTC model <br /> of the Decatur rail network. The model replicates current rail operations within the Decatur <br /> area and could be used to evaluate potential rail activity within the MIP study area. <br /> In addition to these existing models, it is envisioned that the project team will utilize Synchro/SimTraffic <br /> to analyze current traffic operations within the MIP study area. Synchro will be used to evaluate traffic <br /> operations (level of service)at key intersections within the MIP study area. Synchro can be used to <br /> analyze isolated intersections or a series of traffic signals along a corridor,or within a defined <br /> transportation network. Input from the Synchro analysis will be used in SimTraffic to display vehicles <br /> moving through the network which will allow the project team,stakeholders,and the public the <br /> opportunity to see the impacts/benefits of potential transportation improvements. In addition, <br /> SimTraffic produces network wide measures of effectiveness which can be used to evaluate and <br /> prioritize transportation improvements within the MIP study area. <br /> The project team will complete the following work as part of this task: <br /> 1. Traffic Data Collection. It is anticipated that intersection turning movement counts and 24-hour <br /> traffic counts will be needed to support the transportation planning and traffic impact analysis. <br /> The following describes the key elements, and assumptions,for each sub-task. <br /> a. 24-Hour Traffic Counts. Collecting 24-hour counts along key corridors within the MIP <br /> study area will be critical to understanding current travel patterns. It is assumed that <br /> the City,County,and/or IDOT will conduct 24-hour traffic counts within the MIP study <br /> area. The project team will work with the appropriate agencies to coordinate data <br /> collection efforts and to identify specific count locations. Ideally,the traffic counters <br /> would be placed for a full week and would record vehicle classification in 15-minute <br /> increments. This will allow the project team to understand the study area travel <br /> patterns during a typical week and will help the project team identify the peak a.m.and <br /> p.m.travel periods. <br /> A-3 <br />
