TO: HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL

FROM: DIRECTOR OF PUBLIC WORKS

DATE: APRIL 4, 2006

SUBJECT: TRAFFIC SIGNAL PRIORITY LIST

STAFF COORDINATOR: Ron Dragoo, Senior Engineer

RECOMMENDATIONS

1. Consider whether or not to remove this matter from the table.

2. If removed from the table set a date for consideration.

BACKGROUND

Due to budgetary constraints and concern for other traffic signal needs Citywide, City Council requested that the Traffic Safety Commission investigate a program to prioritize the need for traffic signal installation and/or modifications on a citywide basis at their September 10, 2005 joint meeting of the City Council and the Traffic Safety Commission.

On June 27, 2005, the Traffic Safety Commission approved the Citywide Traffic Signal Installation Procedure as shown in Attachment A. Based on the approved Citywide Traffic Signal Installation Procedure, 11 locations have been identified as justifying new traffic signal installations within the City. These 11 locations are identified and ranked in Attachment B. On December 12, 2005 the Traffic Safety Commission approved the attached Traffic Signal Priority List.

A Traffic Signal Priority List establishes a hierarchy of needs for the signalization of unsignalized intersections. As previously stated, it will be used as a planning tool to budget for future traffic signal needs on a citywide basis. It allows for future discussions and analysis of requests for signals to take place within the context of citywide needs. Approval of the Signal Priority List is not a recommendation to install a traffic signal at the location with the highest priority. It is a programming and planning tool to aid in the decision-making when and if funding is available and the need for a traffic signal is warranted.

At the March 7th City Council meeting this matter was tabled.

METHODOLOGY

The recommended traffic Signal Installation Procedure for new signal installations involves three phases. The initial screening process to determine if signalization is justified is determined during Phase I (data collection) and Phase II (analysis). For locations where this process has determined that installation of a new traffic signal is justified and appropriate, Phase III applies criteria to rank the eligible locations. The Traffic Signal Installation Procedure is outlined in Attachment A.

Based on this Procedure, 11 locations have been identified as justifying new traffic signal installations within the City. These 11 locations are identified and ranked in Attachment B. The priority list is being submitted for approval and subsequently will be used as a planning tool to help establish funding priorities through the normal budgetary process.

It is important to note that the Traffic Signal Priority List ranks the need for new traffic signal installations at uncontrolled intersections. Priority for existing traffic signals in need of modifications will be assessed on case-by-case basis. Safety is typically the overriding factor that warrants signal modifications. Funding for safety related improvements to existing traffic signals is sought through available grant programs, maintenance budgets or as additions to other budgeted work. These existing traffic signal locations and projects are intended to be included as independent Capital Program Projects and will be budgeted for accordingly. Additionally, Staff is recommending updating, and presenting the updated, Traffic Signal Priority List to Council annually.

FISCAL IMPACT

There is no immediate fiscal impact to the recommended actions.
