Operational analysis for intersections. The Consultant shall conduct an operational analysis for an intersection (or group of intersections) using at least one of the following software: HCS, TEAPAC, SYNCHRO, SIDRA. The operational analysis shall be consistent with methodologies contained in the 2000 Highway Capacity Manual. Analyses should be conducted for the existing conditions (existing traffic, geometry and signal timing/phasing); and proposed conditions (forecasted traffic, proposed geometry, signal timings/phasing). The Consultant shall conduct a field review to verify the results of the existing operational conditions and calibrate the model appropriately. The output shall be presented in tabular format comparing level of service (LOS), delay, V/C ratio, queue length for existing and proposed conditions. If deemed necessary, the Consultant will conduct a left turn phasing analysis based upon current District 4 Traffic Operations left turn phase warrant guidelines.
Operational analysis for intersections. The Consultant shall determine the existing and proposed LOS utilizing the methodology outlined for arterials in the 2000 Highway Capacity Manual. The analysis shall also indicate LOS analysis for the individual intersections within the segments under study. The Consultant shall utilize at least one of the following software packages for the analysis: SYNCHRO, Signal 2000, HCS. The Consultant may also be required, when directed by the Department project manager, to utilize CORSIM software to evaluate the existing and proposed conditions. The output of the analysis shall be presented in a tabular format comparing LOS, delays, V/C ratios and queue lengths for existing and proposed conditions.
