SUBJECT:
Re-Striping and Lane Changes at the Intersection of
Dublin Boulevard and Dougherty Road
Report Prepared by: Lee S. Thompson, Public-Works Director
ATTACHMENTS:. Diagram of existing and proposed striping
RECOMMENDATION: pprove the striping and lane chan_.oes at the intersection of Dublin
Boulevard and Dougherty Road a~d direct Staff to proceed with
~plementation
FINANCIAL STATEMENT:
Sufficient monies have been budgeted in the Street Maintenance
Operating Budget to make these changes
: (7""DESCRIPTION: At the present time, the eastbound approach on Dublin Boulevard at
": ;':' Dougherty Road consists of one left-turn lane, one through lane and two right-turn lanes. During the p.m.
peak hour, traffic in the through lane backs up' past Dublin Court toward Sierra Court. Based on Staff's
review of mining movement volumes and the signal operation at this intersection, it has been determined
that vehicle backups on eastbound Dublin Boulevard can be reduced significantly by converting the
leftmost right-turn lane to a straight through lane.
The proposed lane conversion will require eastbound through traffic in the converted lane to merge left
within a distance of approximately 300 feet on Dublin Boulevard past the Dougherty Road intersection.
This lane merge will eventually be eliminated when Dublin Boulevard is widened to its ultimate width.
The lane conversion will also require installing new roadside and overhead signs, as well as replacing
some existing signal indications.
As part of the proposed striping changes at this intersection, Staff proposes to re-stripe the southbound
approach on Dougherty Road to add a second left-turn lane. The additional lane will provide the
necessary storage capacity to service this-heavy left-ram movement which is .expected to increase
significantly in the near future as a result of the Eastern Dublin developments. A diagram showing the
intersection lane configurations "before'~ and "after" the proposed striping changes is attached.
In addition to the re-striping, and in response to citizen. requests, a crosswalk will be installed across
Scarlett Court at Dublin Boulevard to facilitate pedestrian access to the East Dublin BART Station.
