• • <br />Existing background data and information (i.e., traffic data) that will be compiled includes: <br />^ existing and planned roadway geometrics; <br />^ existing average daily, a.m., and p.m. peak hour traffic counts, including vehicle <br />profile data to determine the percentage of heavy vehicles (trucks, etc.); <br />^ existing accident data for the past three years; <br />^ existing rail system infrastructure and additional capacity; <br />^ existing and planned transit service descriptions; and <br />^ location of existing and planned bicycle and pedestrian facilities. <br />The sources of the traffic data will include the Texas Department of Transportation and <br />other agency jurisdictions. No original data collection is included in this scope of work. <br />If it is determined that the traffic data available from other sources is not sufficient, we <br />will request a supplemental agreement to cover data collection costs. Additional efforts <br />that will be required to establish the existing transportation resources and conditions <br />include the following: <br />^ collect available mapping, project description, and site plans, including the Bayport <br />Terminal Master Plan. <br />conduct a site reconnaissance (1 trip) to collect information on the physical <br />characteristics of the surrounding transportation network to identify existing <br />roadway cross-sections, intersection lane configurations, traffic control devices, <br />and surrounding land uses. <br />^ analyze service levels of existing infrastructure. This analysis will include up to 20 <br />intersections and/or roadway/highway segments in order to determine the <br />existing base condition. The team proposes to use the Highway Capacity Manual <br />standard software package to analyze level of service. The analysis will be <br />completed for the average daily, a.m., and p.m. condition. <br />evaluate traffic safety and identify the existing conditions of facilities and services <br />related to transit, bicycling and pedestrian activity in the project area will be <br />identified. Traffic safety will be evaluated by identifying accident locations on up <br />to 101ocations in the study area. The accident analysis will compare accident rates <br />at these locations to similar facilities statewide. The source of accident data will be <br />the Texas Department of Transportation and other jurisdictions. <br />The above information will be used to develop analyses of potential impacts that would <br />be associated with construction and operation of the proposed Bayport Terminal project. <br />Potential impacts that will be evaluated include: 1) existing plus construction condition; <br />2) existing plus project condition; and 3) cumulative conditions (with and without the <br />project). <br />M:W'PROACH.WPD 6 <br />
