General Plan Advisory Committee Reviews Traffic and Transportation Data

Post Date:02/02/2018 2:00 PM
An essential component of the General Plan Update currently underway in Sausalito is to gather facts about the existing conditions in our community. Current information about Sausalito's infrastructure, demographics, economy, environmental conditions, tourism, and traffic provides City staff and community residents with a basis for anticipating and directing future change.

At the General Plan Advisory Committee meeting on January 16, 2018, the committee reviewed a report on existing circulation conditions in Sausalito prepared by Parisi Transportation Consulting. In addition to an overview of current state, federal, and local regulations, the report discusses existing conditions in Sausalito related to vehicular traffic, roadway conditions, collisions, parking, public transit, and commuting.

The traffic data for motor vehicles in the Parisi report was gathered in mid-September 2017. Vehicle counts were collected by placing pneumatic tube counters in the roadway segments that serve as gateways into and out of Sausalito.

Facts unearthed by the report include:
  • Total inbound and outbound motor vehicle traffic on an average weekday in Sausalito is 39,000. For the weekend, the figure is 35,400.
  • On an average weekday morning, Sausalito experiences its peak traffic volume of approximately 3,000 motor vehicles (1,700 inbound and 1,300 outbound) between 8:00 and 9:00 a.m. 
  • On an average weekday evening, the peak volume occurs between 5:00 and 6:00 p.m., with approximately 2,900 vehicles (1,300 inbound and 1,600 outbound). 
  • During a non-event weekend, Sausalito experiences its peak inbound and outbound traffic volume of 3,000 motor vehicles (1,400 inbound and 1,600 outbound) between 1:00 and 2:00 p.m.
  • During an average weekend day, Bridgeway has an inbound and outbound traffic volume of 21,100 vehicles. The daily peak occurs between noon and 1:00 p.m., with a total of 1,750 vehicles.
  • The longest waits at traffic lights during evening commute hours in Sausalito are at the intersections of Bridgeway and Johnson Street and Bridgeway and Harbor Drive.
  • Between June 2012 and June 2017, there were a total of 448 motor vehicle collisions in Sausalito. Of these collisions, about five percent (21 collisions) were pedestrian related and about 15 percent (65 collisions) were bicycle related. There were no fatalities.
  • On an average Saturday in the summertime, Sausalito receives an influx of approximately 5,500 bicycles, according to a 2015 study.
  • According to U.S. Census data, 29% of Sausalito commuters commute by bicycle, on foot, or using public transit. For Marin County as a whole, that number is 17%. Sausalito's public transit commuters include 312 individuals who take the ferry and 423 who take the bus.

The General Plan Advisory Committee will continue reviewing traffic and circulation conditions in Sausalito at its next meeting on February 6 at 6:00 p.m. in the Council Chambers. All meetings of the General Plan Advisory Committee are public, and community attendance and participation is encouraged.
