Question Staff and the public
Close public hearing and deliberate
Deny request on the basis that stop signs and a
crosswalk in this location are unwarranted and
would create a false sense of security for
pedestrians
FINANCIAL STATEMENT:
No cost to the City if request is denied. The cost of
a stop sign installation, including Stop Ahead signing
and marking, and a crosswalk would be approximately
$1,000.
DESCRIPTION: In November of 1991, Staff received a letter and
petition from Mrs. Rose Deming requesting that the City consider installing stop
signs and a crosswalk on Lancaster Road at the intersection of Ann Arbor Way. There
is an existing stop sign on the north (Ann Arbor) leg of the intersection. The
reasons indicated in Mrs. Deming's letter are (1) reduction of speed and (2) to
provide a safe crossing for children going to school. The Traffic Safety Committee
subsequently studied the intersection, and Mrs. Deming was advised that Staff
recommended against the stop sign installation. Mrs. Deming has requested that the
City Council review her request and Staff's findings, which are as follows.
Lancaster Road is a neighborhood street which parallels Amador Valley Boulevard and
forms a straight line between York Drive and Penn Drive. York and Penn are
collector streets which form a loop around the Wells/Cronin School sites and enter
Amador Valley Boulevard. Ann Arbor Way forms a "T" intersection with Amador Valley
Boulevard at its north end and with Lancaster Road at its south end.
There are presently school (yellow) crosswalks across Lancaster Road at both Penn
Drive and York Drive, and there are single-approach stop signs for traffic entering
York and Penn from Lancaster Road. There are crosswalks across Amador Valley
Boulevard at both Penn Drive and York Drive, and also at Burton Street. The Burton
Street intersection is controlled by three-way stop signs and has an adult crossing
guard during the hours that children are going to or coming home from school. It
was intended that children going to school utilize the existing crosswalks. Mrs.
Deming's letter states that the crosswalks at York and Penn Drives are not
convenient for some children and that they tend to cross the street at any location
along Lancaster.
Staff requested that TJKM, the City's traffic engineering consultant, prepare a
report concerning this request. TJKM's report is summarized as follows:
Volume Warrants
The highest 8-hour vehicular volume entering the intersection was a total of 264
vehicles. As indicated on the attached warrants, the minimum volume warrant is 300
vehicles per hour for the highest 8 hour period. Therefore, the vehicular volume
(average 33 per hour) at this intersection falls far short of this warrant. TJKM's
ITEM NO. COPIES TO:
volume warrant, which the City has used for stop sign studies in the past, is lower
than the State warrant of 500 vehicles per hour.
Pedestrian counts were conducted during the times of day that children would be
walking to school. During the morning count, 8 pedestrians and 3 bicyclists crossed
Lancaster Drive southbound at Ann Arbor. There were no pedestrians or bicyclists
crossing in other directions. During the afternoon count, no pedestrians or
bicyclists crossed in any direction. It should be noted that the afternoon count
was based on the time of day that children would be leaving Frederiksen School
rather than Wells School, as TJKM focused on the safety of younger children. TJKM's
report states that the school departures are spread over a wider range of time than
the morning arrivals, which would tend to reduce the number of pedestrians per hour.
Accident Warrants
There have been no reported accidents at this intersection since Staff began
maintaining its accident map in 1984. The accident warrant is five or more
accidents per year of a type correctable by stop signs. Therefore, the accident
warrant is not met.
Visibility
Lancaster Road is a level street with clear visibility in both directions for well
over the warrant of 160 feet.
Speed
A speed survey reveals an 85th percentile speed of 22 mph westbound and 26 mph
eastbound. Overall, 90% of the vehicles recorded were traveling under 25 mph.
one of the 341 vehicles recorded was traveling over 30 (and less than 35) mph.
Only
Conclusion
Based on the criteria listed above, Staff feels that the intersection of Lancaster
Road and Ann Arbor Way does not meet the warrants for multi-way stop sign
installations. The intention behind installation of stop signs is to assign right-
of-way at intersections and to reduce the number of accidents. Stop signs are not
an effective means of speed control. While the speed of vehicles may be reduced at
the intersection itself, motorists tend to speed up between stop signs; therefore,
speeding would not be alleviated.
When stop signs are installed in locations where there is little cross traffic,
drivers tend to come to rolling stops or to ignore the stop signs completely. A
pedestrian or bicyclist, particularly a child, may feel falsely secure crossing the
street at a stop intersection when, in fact, an oncoming vehicle may not come to a
stop. Additionally, drivers who develop the habit of ignoring unwarranted stop
signs may also ignore stop signs that are warranted. Most drivers are law-abiding
and have no intention of violating traffic regulations; however, when an unwarranted
restriction is imposed, it may result in unintentional violations.
Stop signs also add to the pollution problem by increasing the amount of gasoline
used by cars in starting and stopping rapidly.
Regarding the matter of the crosswalk, pedestrians also tend to feel safe in a
crosswalk and may step out into the street in front of oncoming traffic.
Conversely, pedestrians tend to look for cars more carefully when the "protection"
of the crosswalk is not there. In this case, crosswalks exist within a block or two
of the Lancaster/Ann Arbor intersection, and Staff recommends that children walking
to either Frederiksen or Wells School utilize the existing crosswalks.
Staff recommends that the City Council conduct a public hearing, deliberate, and
deny the request for stop signs and a crosswalk on Lancaster Road at Ann Arbor Way.
