TASK 3 _. DATA COLLECTION & FIELD REVIEW Traffic Data Peak weekday intersection turn movement counts will be compiled from existing and new count data for up to 47 roadway intersections. Intersection turn movement counts will be conducted from 7:00 a.m. to 9:00 a.m. and from 4:00 p.m. to 6:00 p.m. during weekday periods. We will check with the City and see whether any City -conducted counts and/or counts from other area traffic studies could be utilized for some study intersections. Weekday daily traffic counts will be conducted for 20 roadway segments. KOA will also conduct a comparison of traffic count data (the new 2016 traffic counts with the 2007 counts) to understand the traffic pattern/circulation changes and volume growth or decreases within the study area. Field Review KOA will review the roadway segments and intersections in the field to observe and inventory roadway geometries, existing traffic operations, base line width, striping patterns, and traffic. Signal timing and phasing information will be obtained from the City as well. Cumulative/Area Projects A list of cumulative/area projects will be compiled in the surrounding area, from both the City of Santa Ana and the City of Tustin. Trip distribution patterns for those cumulative projects will be provided by KOA for City staff's review and approval before assigning those cumulative projects to the roadway system. Land -use GIS Database KOA will provide a traffic analysis zone (TAZ) map to the City, for use in processing land use data. It is assumed that geographic information systems (GIS) files will be exchanged directly between KOA and the City for this purpose. Land use totals provided by the City, including residential unit totals and commercial/industrial square footage values, will be input into the traffic analysis and analyzed for incremental impacts of new development. Land use data for both existing land use intensities and planned intensities at buildout will be required from the City. Land use data will be used as the input for long range traffic volume forecasts through the traffic analysis model. Related Documents KOA will review relevant traffic and parking studies and documents containing traffic analysis conducted in the area. Other documents, such as the City's general plan updates and the recent downtown and central Santa Ana complete streets plans, will also be reviewed. TASK 4 — REPORT PREPARATION & DEFINITIONS KOA will prepare a traffic study report that will include the following (at a minimum): • Existing Conditions Intersections k Roadway Segments * Transit Service • Project Related Traffic Volumes Accident Data and Safety Evaluation Pedestrian and Bicycle Circulation Traffic Changes Based Upon Circulation System Improvements Trip Generation 10 25E-14
