Mr. Brozosky clarified that staff is saying this is the current model, later it will say how it affects the network and then will ask for the various combinations to be run on the model to see the effects before making a decision or policy change? Mr. Knowles agreed and gave an example that if the model shows West Las Positas, with fronting residential units, makes no difference with two lanes or four lanes, it might be determined that the road should stay two lanes. Mr. Brozosky agreed with that because that would not be a cut through route, but Hopyard could become an alternative route that would change significantly based on other arterial changes in the city. Mr. Knowles said everything has pros and cons. For example, Del Valle and Hopyard is a four-way stop intersection. The General Plan assumes it is a traffic signal. That will affect how much volume is on Hopyard, because a lot less can use it if it is a four way stop. Also if you increase the capacity on Hopyard, how much more traffic do you want to bring to Division Street or Del Valle Parkway? Mr. Brozosky was unclear how to use the model data presented at this meeting for future decisions, if all the other data will be changing. Mr. Knowles said he was trying to present the kinds of data available to acquaint everyone with how the traffic model works. There was discussion about whether to proceed with the staff presentation in order to hear from the public or whether to postpone the remainder of the presentation for the next workshop. It was determined to proceed with the staff report. Mr. Knowles reviewed the widening of Dublin Canyon Road. There was discussion about the definition of regional cut through traffic and local cut through traffic and whether local cut through could be tracked on the model. Mr. Knowles referred to the staff report and using Foothill Road as an example, it was possible to summarize who is using a particular section of the roadway. Mayor Hosterman indicated there would be another workshop on January 25 and asked staff is it could continue to review potential road widenings at that time? She asked the Council and Commission if anyone had further questions to ask staff to present at that meeting. Mr. Brozosky referred to Figure 19 on page 39 of the staff report, which shows Foothill Road. He asked if it were known where the trips started or ended for the trips on that road? Is there a way to analyze whether a person is using the road for a specific reason or just to avoid other congested areas? Mr. Knowles said he could show where all northbound traffic originated; or he could indicate who used that road for various destinations. Displays are not created until it is known if it would be useful in making decisions. He also noted the models can show how traffic changes over time.
