Item Defeated by the Traffic Review Board at their February 11, 2003 Meeting
1)
REQUEST TO INCREASE THE SPEED LIMIT ON ALGOMA BOULEVARD
BETWEEN HIGH AVENUE AND MURDOCK AVENUE FROM 25 MPH TO 30 MPH.
[EXISTING CONDITION: 25 MPH SPEED LIMIT].
This is request from a Boardmember.
The City Transportation Department conducted a speed survey on Algoma Boulevard between
High Avenue and Murdock Avenue during January 2003. The results are summarized below:
SPEED SURVEY
ALGOMA BOULEVARD BETWEEN HIGH AVENUE AND MURDOCK AVENUE
JANUARY 2003
Direction Average Speed
85th Percentile Daily Traffic Volume
NOrthbound 30.3 34.2 4,889
Southbound 33.2 38.1 4,853
The posted speed limit is 30 mph. This section of Algoma Boulevard is a new four lane roadway
in a residential area. This portion of Algoma Boulevard is also a state highway.
The 85th percentile speed is 34.2 mph for northbound and 38.1 mph for southbound. The 85th
percentile speed is normally used tO establish speed limits.i It is assumed that 85% Of ali drivers
will drive at a speed that is reasonabl~ and prudent. In short, the 85th percentile speed is the
collective judgement of what drivers feel is a safe speed. I normally reduce the 85th percentile
speed by 5 mph to 7 mph, due to enfomement issues, to determine an appropriate speed limit.
This method would indicate that a 30 mph speed limit would be appropriate for this section of
Algoma Boulevard. It has been shown that an increase in the speed limit doesn't necessarily
increase the average speed by the same amount. A 1999 study on Bowen Street showed that a
5 mph increase in the speed limit resulted in an increase of only 1 mph to the average speed.

2)
REQUEST FOR A FOUR-WAY STOP SIGN AT THE INTERSECTION OF LINWOOD
AVENUE AND SHERIDAN STREET. [EXISTING CONDITION: STOP SIGNS ON
LINWOOD AVENUE].
This is a request from a citizen. There is currently a stop sign on Linwood Avenue at its
intersection with Sheridan Street.
The first step in determining the need for a four-way stop is to examine the warrants. The
warrants for a four-way stop are shown below:
a)
b)
c)
d)
At least 500 vehicles per hour entering the intersection from all approaches during
any eight (8) hours of an average day, and;
The vehicular volume crossing the major street averages at least 200 vehicles for the
same eight (8) hours, and;
The traffic volumes are approximately equal in distribution and;
Five or more right angle accidents in a twelve-month period.

The accident history for this intersection is shown below:
Intersection 2002 2001 2000
Linwood Avenue and Sheridan Street 4 2 1
The accident rate for 2002 is high, but I'm not sure if the higher rate was driven due to the
construction on Algoma Boulevard. The last six (6) accidents were all right angle type
accidents. The following table shows the actual breakdown.
Date Type Direction
1/28/01 Right Angle N/W
5/29/01 Right Angle N/E
8/10/02 Right Angle N/E
9/23/02 Right Angle S/W
10/30/02 Right Angle N/W
11/2/02 Right Angle S/E
This intersection is nearing five (5) right angle accidents in a twelve-month period. If the
Board is going to base its decision on one year's data, I believe we should at a minimum show
five (5) accidents.
I would also like to point out a new trend in the traffic engineering field that may wan'ant
some consideration. Some cities in an attempt to reduce speeding in residential
neighborhoods are limiting the length of an unimpeded street. The maximum unimpeded
length is set at 1,200 feet, if the following criteria are met.
· 1,000 or less vehicles per day.
· Intersects an arterial street.
· Functions as a neighborhood entrance street, or
· Is a likely cut-through street.
Sheridan Street would qualify if the Board is willing to accept the above guidelines for furore
requests on low volume resident streets. The above standards have not been adopted on a
national basis, but it is something to consider.
