missed and struck the roundabouts. The third accident was a DUI where the driver was under the influence and struck the roundabouts. Another accident involved a vehicle beyond the traffic circle and the driver decided to change lanes into the lane going in the other direction, which caused an accident. Another accident involved a truck, which was trying to navigate around the traffic circle and could not clear it and rather than stay with the turn, the driver went to the outside and hi-sided the vehicle and became stuck. Another accident involved a speeding vehicle and another accident involved a driver going at a reasonable speed but did not navigate the traffic circle appropriately. Mr. Sullivan asked what the added benefit would be in designing Vineyard Avenue between Montevino Drive and Bernal Avenue as a four-lane street with medians versus leaving it as two lanes? Mr. Wilson said there is an added benefit in terms of gaining additional capacity for a small section of the streel. The main concerns would be the two lanes coming in and what the intersection improvements would look like. In terms of weighing this benefit versus the traffic calming aspects, staff believed the traffic calming aspects weigh heavier and that is why staff is recommending two-lanes; however, the traffic model does show some benefit for four lanes but it is not to the extent that staff would recommend given that the traffic calming aspect is preferable. Mr. Sullivan did not believe it seemed reasonable that there was significant traffic congestion to make Vineyard Avenue between Montevino Drive and Bernal Avenue into four lanes. Mr. Wilson said he was not disagreeing with Mr. Sullivan; however pointed out that four lanes would allow for vehicles to move around each other and add additional capacity in that section. In response to an inquiry by Mr. Sullivan, Mr. Wilson said there would be a lane in each direction but the median would be much wider. Mr. Sullivan asked if there was a need for a traffic signal at Petronave Lane beyond the street access? Mr. Wilson said staff would recommend a traffic signal because the issue is there are very few homes that come out of this vertical location. The City created a difficulty for itself in terms of geometries and the issue is that there is a minimal amount of stopping time as a vehicle comes over the hill on Vineyard Avenue. If the question of pedestrian access was removed, Mr. Sullivan asked if staff would still recommend a traffic signal at the intersection of Vineyard Avenue and Petronave Lane? Mr. Wilson said another potential option would be to make this intersection only a right turn out from this location so that traffic does not have to cross two lanes. Jeff Knowles, Deputy Directorrrransportation, said staff would have emphasized increasing the site distances at this particular location because there is little traffic and anywhere else in the City under these circumstances, staff would not build a traffic signal and look for some other alternative. With the trail crossing and wanting to encourage children to be able to cross safely, there was no option other than a traffic signal. Pleasanton City Council 16 1 0/04/05 Minutes
