MEMO 100 Webster Street, Suite 300 Oakland, CA 94607 www.altaplanning.com To: Ruchika Aggarwal and Rafael Rius (City of Palo Alto) From: Hugh Louch and Kyle James (Alta Planning + Design) Date: January 3, 2019 Re: Middlefield North Road Diet Evaluation – Technical Memorandum
Introduction To improve traffic safety conditions on Middlefield Road in northwest Palo Alto, the City of Palo Alto tested a temporary re-configuration of the roadway on Middlefield Road from the north City limit (San Francisquito Creek) to Forest Avenue. This technical memorandum documents the impacts of the one-year test for the Middlefield North Road Diet Evaluation for the segment of the roadway between Palo Alto Avenue and Lytton Avenue and divides the test into three evaluation periods:
Pre-pilot: Prior to construction of the temporary re-configuration (summer 2017) Mid-pilot: The first three (3) months after construction of the temporary re-configuration (fall 2017) End-pilot: The last three (3) months before concluding the temporary re-configuration (summer 2018)
At the conclusion of the end-pilot period, the project will be presented to Palo Alto’s City Council for adoption as a permanent feature along Middlefield Road, for modification, or for reversal to pre-pilot conditions. To help inform the City Council’s decision, the City of Palo Alto identified a series of performance measures within five (5) categories to track over the life of the project: 1. Health & Safety o Reported collisions o Observed near-miss collisions o Hazardous maneuvers o Motor vehicle speeds o Outdoor sound levels 2. Intersection Impacts o Intersection turning movement counts o Intersection level of service o Intersection queue lengths 3. Traffic Diversion o Traffic volumes o Motor vehicle classifications 4. Travel Reliability o Motor vehicle travel times and buffer time indices o Transit running times 5. Public Opinion o Resident survey responses
