Task 3.2-Existing Conditions Memorandum CONSULTANT is intimately familiar with the previous work performed the within the study area. Based on CONSULTANT's knowledge of the available data, it is recommended that new counts be collected for vehicles (autos/trucks), bicycles and pedestrians within the study area that represent the current 2013 conditions. All of the counts in the Woodside Road corridor will be collected on the same day for use in the microsimulation of the study area. To the extent feasible, all of the intersections counts, including the isolated intersections on Maple Street and Chestnut Street, will be collected on the same day. In addition to the traffic counts, field observations will be made and GPS-based travel time data will be collected for the Woodside Corridor at the same time as the intersection turning movement counts to support preparation of a microsimulation model that accurately reflects the observed conditions in the field. The new traffic data will be used to prepare a SimTraffic microsimulation of SR84/ US101 Interchange study area. The simulation will include the seven existing intersections in the Woodside Road corridor. Because of the closely spaced intersections in the corridor, the high levels of existing congestion, and potential increase in demand expected from new land uses, a microsimulation model is needed to assess the local street operations as a system rather than as isolated intersections. The simulation will account for the congestion that occurs between the Woodside intersections during the peak periods. SimTraffic is considered a microsimulation model, since it models individual vehicles traveling through the roadway network and accounts far both driver behavior and vehicle perfarmance. SimTraffic also models the traffic signal control equipment operation including the signal timings, phasing and coordination with adjacent intersections. This type of simulation is in contrast to deterministic traffic models, like Highway Capacity Manual 2010, Traffix or Synchro, that are commonly used for intersection level of service analysis. Deterministic software only consider the traffic flows at a single intersection without assessing the impacts that can occur due to upstream and downstream intersection operations. Freeway operations on US 101 will also be evaluated using the FREQ traffic model. CONSULTANT will study the freeway segments between Marsh Road and Whipple Avenue. The analysis will include the Woodside Road on- and off-ramps as well as the on- and off-ramps at Marsh Road and Whipple Avenue that feed into the Woodside interchange. The FREQ model provides key measures of effectiveness including: vehicle density, level of services, travel time, travel speed, and queuing at on-ramps. In addition, FREQ will can produce results related to fuel consumption, vehicle delay (vehicle hours), personal delay (VH) and maximum delay experienced within the study area. Subtask 3.2.1 -Review of Available Data&Reports In addition to reviewing the five operations studies conducted for the Caltrans facilities, CONSULTANT will review the analyses developed far the Downtown Specific Plan, General Plan Update and recent EIRs prepared for developments within the Broadway Corridor.
