Lincoln Avenue/Marshall Way/Pacific Avenue Improvements

StudyAreaImage.jpg

Announcement: City staff/consultant team presented existing conditions and initial findings including comments received from the first round of outreach for the Lincoln Avenue/Marshall Way/Pacific Avenue Improvement Project at the Transportation Commission meeting on May 25, 2022, and sought direction on a grant, which was submitted on June 30, 2022 for the west end part of the corridor between Main Street/Central Avenue and St. Charles Street. 

Background

The City has identified the Lincoln Avenue/Marshall Way/Pacific Avenue corridor between Alameda Point at Main Street/Central Avenue and Broadway in the east end of town as a high priority for safety and mobility improvements.  City staff is working with Parisi Transportation Consulting to develop a safety and operational concept for the corridor.

Existing Conditions: The corridor connects neighborhoods across Alameda, is over three miles long, and serves multiple destinations including schools, commercial districts and parks.  It is also a high injury corridor with several high crash intersections according to the City's Vision Zero Action Plan.

Project Description: This project will develop a transportation concept by evaluating the current uses, intersection controls and crash data.  Community involvement is a priority as the roadway serves many different users.  The final concept will likely be phased in over time as street sections are resurfaced and improvements are constructed with grant funding.  City staff and the consultants are considering a road diet, which has the potential to reduce crashes by up to 47 percent when going from four to three lanes with a center turn lane and bikeways.  City staff/consultant team also is considering roundabouts, which reduce fatal and severe injury crashes by 90 percent compared to traffic signals or all-way stops, and could be considered where space exists such as the Lincoln Avenue/Constitution Way/Eighth Street intersection or the Lincoln Avenue/Fifth Street/Marshall Way intersection.

Project Goals

For the Lincoln Avenue/Marshall Way/Pacific Avenue Improvements, the City seeks to:

  • Promote safety by prioritizing Vision Zero, which the City Council approved as a policy in 2019 to reduce traffic deaths and severe injuries to zero 
  • Improve mobility for all roadway users, including AC Transit buses
  • Improve pavement for better operations and user experience, and to reduce maintenance
  • Provide flood reduction and landscaping opportunities
  • Reduce greenhouse gas emissions by improving traffic flow and shifting to walking, bicycling and riding transit
  • Comply with City plans & policies including the City’s General Plan update and Draft Active Transportation Plan

Strategies under Consideration

City staff/consultant team will consider various strategies to improve safety and mobility such as road diets and roundabouts as described below.

Road Diets

The reduction of motor vehicle travel lane(s) provides an opportunity to reallocate space for other uses such as bike lanes and a center two-way left-turn lane.  According to the Federal Highway Administration's informational guide(PDF, 2MB), streets with motor vehicle travel lane reductions have multiple benefits for people driving, walking and bicycling, such as:
  • Decreases vehicle travel lanes for pedestrians to cross;
  • Allows for better visibility of pedestrians waiting or attempting to cross the street;
  • Improves circulation for bicyclists when a bikeway is added;
  • Reduces rear-end, sideswipe and left-turn collisions by at least 19 percent and up to 47 percent through the use of a center two-way left-turn lane;
  • Improves speed limit compliance by three to five miles per hour, which reduces the severity of collisions; and
  • Improves travel flow since through vehicles are separated from left turning vehicles.

The Federal Highway Administration (FHWA) has a case studies document and additional resources.  FHWA Video and Fact Sheets are as follows:

Roundabouts

Roundabouts reduce the types of crashes where people are seriously hurt or killed by up to 90 percent when compared to conventional stop-controlled and signalized intersections.  Roundabouts result in lower vehicle speeds around the roundabout.  Crashes that occur will be less severe because of this reduced speed and the more “sideswipe” nature of crashes.  Pedestrians are generally safer at roundabouts, and are faced with simpler decisions at a time. Videos and presentations on roundabouts are as follows:
