Common use of Traffic and Operational Analysis Clause in Contracts

Traffic and Operational Analysis. The Engineer shall review and analyze traffic data (including percent trucks, design hourly volume, and directional distribution), existing roadway features (including ramp locations, weaving sections, number of lanes, offset to obstructions, lane widths, frontage road operations, and intersection operation and geometry), traffic flow patterns, accident patterns and frequencies, and transit and traffic operations. The Engineer shall develop and calibrate a model of the existing traffic. The Engineer shall include the calibration of the model in the traffic analysis report and Interstate Access Justification Report (IAJR). The Engineer shall perform a detailed level of service analysis with CORSIM, PASSER, HCS, VISSIM, SYNCRO, or other acceptable model for the current year using current traffic and geometric conditions and for the build year and 20 year design year using traffic projections and proposed geometric designs to compare different geometric alternatives and ramp patterns. The Engineer shall incorporate the results of this analysis into the schematic design. The Engineer shall develop a traffic analysis report summarizing all analysis performed.
