CR 08-068 Results of Cambridge Street Traffic StudyHOPKINS
July 11, 2008 Council Report 2008 -068
Proposed Action
Staff to install additional traffic control at Texas Avenue and Cambridge Street. No
Council action requested.
Overview
In accordance with Legislative Policy 8 -A, the petitioned traffic study for Cambridge
Street has been completed. The study finds that traffic volumes, while well within the
capacity of the street, are influenced by Hwy 7 cut through traffic. The following charts
show the combined, eastbound, and westbound traffic counts by speed and time. As can
be seen on charts, nearly all eastbound traffic is at or near the speed limit of 30 mph
(yellow line). In contrast, 16% of the westbound traffic is going 40 mph or faster (red
line). Both volumes and speeding are at their highest during the noon and late pm rush
hours.
We recommend installing a no right turn sign on southbound Texas Avenue at
Cambridge Street to reduce the number of cut through vehicles and speeders on
Cambridge Street. The no right turn would be in effect from 11:00 am to 6:00 pm
Monday through Friday only. Additionally, we recommend installing a no U turn sign to
prevent drivers from making a U turn and then a left turn onto Cambridge Street.
This signage may have the impact of pushing some traffic onto Oxford and Lake Streets.
However, because these streets do not have signals at Blake Road, vehicles attempting to
make left turns onto Blake will have a very difficult time. This should moderate any
impacts to these streets. We will be conducting traffic counts before and after the signs
are installed to measure the impact on these streets.
Residents on Cambridge Street will need to access their properties from Blake Road
during these hours.
We have been in contact with the lead petitioner and other residents and the response to
our study and recommendation has been positive.
