Dowling Associates, Inc. Transportation Engineering Planning Research Education Collection of Existing Count Data The validation of the travel model and the evaluation of 2009 baseline conditions will require compilation of existing traffic counts to compare to model results and input into Synchro. Dowling Associates will obtain all recent link and intersection counts from the City of Pleasanton. In the past, the City has provided all of the traffic intersection and cut through count data required for the analysis of existing baseline conditions. We know that there are loops available at many locations but also realize that the City may have limited staff resources to conduct a full fledged count program in support of the model revalidation and baseline analyses. As an option, we have teamed with Quality Counts and the City may elect to use them to complement the City's ongoing count program, count hot spot locations, or provide a check on suspect counts. For budgeting purposes, we have provided an optional fee per intersection count as well as an overall cost if a full count program were requested. The valuable part of having Quality Counts provide their services is their unique approach to collecting data. Quality Counts has implemented video based technology to capture turn movement counts and similar types of surveys. The ability to temporarily install a video camera that minimizes obstructions enables an intersection view that cannot be obtained by field staff. In addition, the placement of multiple cameras can be used at congested locations to review traffic demand volumes that may not clear within a given signal cycle. The video based collection allows for the freedom to rewind, replay, and check over data collection ensuring clients the utmost detail and accuracy. Intersection turn movement counts authorized for use in the model update and 2009 baseline analysis will be entered into an Excel database. Dowling Associates has already related the study intersection nodes in the travel demand model to the north/south /east/west legs of the Synchro intersections. This link will allow us to efficiently upload the new AM and PM traffic counts into the travel demand and Synchro models. Review of Existing Traffic Model Dowling Associates is very familiar with the City's current version of the travel demand model. We developed the first travel demand model for the City in 2002 in •ransCAD and then later converted it to the Citilabs suite of programs. It has many elements that are unique to a City travel demand model such as: A "Master" network which stores the network related attributes for the existing base, approved. and buildout conditions, including number of lanes, facility type, and ramp metering assumptions. Trip generation based on 60 land use categories with ITE Trip Generation rates. Detailed calibration to replicate commute trip patterns and cut through traffic based on surveys. School trip distribution based on specific school district boundaries. A relationship with MTC regional travel demand model for estimates of non -auto trip percentages. Peak hour spreading which considers congestion between each origin and destination. Customized scripts for tracking potential impacts of land use development projects or roadway alternatives. A direct link to the City's Synchro /SimTraffic network for operations analysis and traffic simulation. For this task, Dowling will consult with City staff and other users of travel model output, including other consultants, to determine which features of the current model system should be reconsidered or updated.
