Traffic Forecasting Methodology Sample Clauses

Traffic Forecasting Methodology. Objective To develop a uniform approach to developing traffic forecasts for use in the environmental analysis that includes addressing the impacts of the implementation of tolls. Given the complexity of localized issues, a multiple step process will be needed using the statewide model for regional traffic shifts and for areas outside of the local MPO model areas. For areas where local models are available, the statewide information will be used in conjunction with the MPO models to develop the appropriate forecasts. The proposed methodology must address the full implementation in the horizon year but also must address staged implementation. It must also be able to address the impacts of changes to toll rates. Activity The CONSULTANT will perform the following activities: • Review previous interstate tolling environmental efforts (local and other states) and summarize methods/outcomes reflecting on any lessons learned and best practices related to traffic forecasting methodologies. • Develop draft traffic forecasting requirements for both corridor and off-corridor locations. This should address all needs for NEPA and design. They should outline time periods, level of detail (segment, ramp, intersection), with and without tolling, ranges of toll rates, differentiation between trucks and cars. • Review draft traffic forecasting requirements with appropriate agencies. This effort includes meetings with the MPO’s to discuss their models and share the forecasting methodologies with them. (Assumes up to 10 meetings) • Based on input a final set of traffic forecasting requirements will be developed • Review available models/tools/data to determine the suitability for producing traffic assignments in tolled conditions and its ability to work with the statewide model. Key details to be reviewed model temporality, value of time, traffic data accuracy, network and zonal details (existing and future), assignment algorithms used, current and forecasted socio-economic data used and other critical aspects of the model. (assumes up to 14 MPO models, the statewide model and other national tools & data sets) • A draft project-level traffic forecasting framework will be developed that details how to stitch the models together into a smooth forecasting tool capable of developing traffic forecasts for different toll rates, different implementation years, and multiple scenarios. The model framework will essentially a GIS coverage that utilizes the inputs and outputs from the ava...
