left turn lanes ohio wayne-greeley 7/14/1980July 14, 1980
TO: Rufus Nye, City Manager
FROM: Dean Boyer, City Engineer
SUBJECT: Left turn lanes at intersections on South Ohio
Street between Wayne Avenue and Greeley Avenue
We propose to construct left turn lanes within the existing
median strip at ten (10) "T" intersections and eight (8) full
intersections, plus increasing the capacity of the existing
left turn lanes at the McAdams Road and Republic Avenue inter-
section.
Recent improvements that have been made on Ohio Street,
such as the slip-on frontage road south of Cloud Street and
the left turn lane on the south leg of the Ohio Street and
Shalimar Drive intersection, have been paid for by the
property developer that desired their use. Also, it has
been proposed that the left turn lane at Edison Place to
serve the Kansas Power & Light Co. complex be paid by the
developer. '
The estimate of cost to complete the twenty (20) inter-
sections in paragraph one is $185,600.00.

REVIEW OF SALINA JOURNAL ARTICLE ON FEBRUARY 27, 1981
REGARDING OHIO STREET TRAFFIC
1. Article states that in the twelve (12) month period prior to the
change of speed limit, there were only twelve (12) accidents on
this section of Ohio Street. Our records show that there were
twenty-nine (29) accidents during this twelve (12) month period.
2. The article mentions a study involving a nine (9) month period
after the speed limit change. However, the period from July 1,
1980 to March 1, 1981 is only eight (8) months. The speed limit
change was effective July 8, 1980.
3. In the eight (8) month period prior to the speed limit change,
there were twenty (20) accidents compared to twenty-three (23)
accidents during the eight (8) month period following the speed
change.
4. Even though the speed limit was reduced to 30 M.P.H., the actual
speed is still 36.5 M.P.H. (speed study conducted September 1980)
after the change as compared to 39.3 M.P.H. before the reduction.
5. Drivers on side streets are misjudging the speed of the vehicles
on Ohio Street thinking they are traveling at 30 M.P.H., when
in fact they are traveling 36 or 37 M.P.H.
6. The accident reports do not estimate the damage involved in the
accidents. It is my guess that the seriousness of the accidents,
after the speed reduction, is less than before.
7. There were several accidents after the speed change that were
unusual. Three (3) accidents were due to mechanical failture;
two (2) of these were trailers that came loose from vehicles
and were not speed related. One (1) accident involved an illegal
parked car on Ohio Street and four (4) accidents were one (1) car
accidents, hitting fixed objects.
8. The severity of the winter plays a big part in the number of
accidents we have in the city. This may have a lot to do with
the reduction of the number of accidents throughout the city
as mentioned in the article. The winter of 1979-1980 was much
more severe than the winter of 1980-1981. In the eight (8). month
period prior to the speed change on Ohio Street, there were
three (3) accidents caused by ice or snow, compared to one (1)
accident after the speed change.

STREET TRAFFIC
Page 2
March 5, 1981
In summary, it is my opinion that if the actual speed on Ohio
Street was near or under 30 M.P.H., there would be less accidents
with less severity. But the fact is, the 10 M.P.H. speed limit
reduction only reduced the actual speed 2 to 3 M.P.H. This is not
a case of comparing a 30 M.P.H. speed to a 40 M.P.N. speed. It really
is a comparison of a 36.5 M.P.H. speed with a 39.3 M.P.H. speed. A
2.8 M.P.H. speed reduction has not and will not have appreciable effect
on the accident rate on any street. Prior to the reduction of the
speed limit, there were 13% to 15% of the vehicles on Ohio Street that
exceeded the speed limit of 40 M.P.H. After the posted reduction to
30 M.P.H., there were 64% to 66% of the vehicles exceeding the speed
limit of 30 M.P.H.
The major reason for the accident on this section of Ohio Street
is that the drivers on the side streets, wishing to cross or enter the
traffic flow of Ohio Street, are misjudging the speed of the Ohio Street
traffic. This misjudgment is understandable when a large per cent of
the vehicles are traveling 6 to 7 M.P.H. over the speed limit.
