Common use of Traffic Data and Projections Clause in Contracts

Traffic Data and Projections. The Engineer shall develop the opening-year, design-year (opening year +20) and pavement design year (opening year + 30) travel forecasts, and related traffic analysis in coordination with State Transportation and Programming Division (TPP). The developed traffic projections must be utilized for design and environmental analysis. The Engineer shall develop traffic forecasts for the main lanes, ramps, cross streets, interchanges, intersections, and frontage roads for no-build and build alternatives. These projections must include graphic representations of the anticipated daily movements along the corridor (suitable for inclusion in the design schematic and environmental document) and the Traffic Analysis for Highway Design table. The Engineer shall prepare a Traffic Projections Methodology memo, based on the information provided in the traffic analysis package. The Engineer shall review the proposed methodology with the State and shall refine it based on these discussions. Traffic volumes developed by the Engineer will be submitted to TPP for review and approval, and the Engineer will revise the traffic volumes based on TPP’s comments. The Engineer shall perform travel demand modeling analysis to develop traffic volume forecasts appropriate for the level of traffic operations analysis required based on project needs. The travel demand modeling analysis must be based on regional metropolitan area planning organization travel demand models, statewide area analysis model, and/or other standard practice and guidelines depending on the study area of each project.

To accomplish this effort the Engineer will: The Engineer shall perform travel demand modeling analysis to develop traffic volume forecasts appropriate for will calibrate/validate the level base year model. This is an iterative process that involves the execution of traffic operations analysis required based on project needs. The travel demand modeling analysis must be based on regional metropolitan area planning organization the travel demand models, statewide area analysis modelcomparison of modeled traffic volumes to observed counts, and/or other standard practice adjusting the travel demand models, and guidelines depending on repeating the process until acceptable match is obtained. A. Obtain regional Travel Demand Model (TDM) B. Detail code the roadway network within the study area of each project.limits C. Develop and apply regional impedance factor to offset additional impedances created by detail coding the study area
