traffic study crawford & 2nd 3/3/1975March 3, 1975
TO: Keith Rawlings, Director of Planning
FROM: D. W. Bassett, Traffic Engineer
As requested by Jim Maes, Assistant Planning Director,
the Traffic Engineering Department conducted a study of the
traffic at the intersection of Crawford Avenue and Second
Street.
Please find attached the following reports:
1. Peak hour traffic counts.
2. Peak hour traffic counts showing
turning movements.
3. Intersection capacity work sheets
showing the general conditions of
the intersection.
4. - 7. Design capacity analysis charts
of all four approaches to the
intersection.
Our study indicates that for a level of service "B", Crawford
Avenue can accommodate approximately 2,300 vehicles per hour, a
total of both approaches. Second Street can accommodate approxi-
mately 350 vehicles per hour, a total of both approaches.
The present peak hour traffic volume on Crawford Avenue is
approximately 615 vehicles per hour, a total of both approaches.
The present peak hour traffic volume on Second Street is approxi-
mately 35 vehicles per hour, a total of both approaches.
The study indicates that the existing traffic volume at this
intersection is far below the design capacity of the intersection.
Our study indicates that the traffic volume at the intersection
of Second Street and Prescott Avenue also is far below its design
capacity.
The accident record at these intersections indicate that there
were two non -injury accidents at each of the intersections during
1974. There were no traffic accidents on Second Street between
Crawford Avenue and Prescott Avenue for this same period.

Our study revealed that there are several vehicles parking
on Second Street between Crawford Avenue and Prescott Avenue.
Parking permitted on both sides of a 32 -foot pavement can
create some congestion. However, due to the low traffic 'volume
on Second Street the traffic congestion and inconveniences to
drivers would be insignificant.
One method of reducing congestion in this area would be to
restrict parking on one side of the street. This would create
two 11 -foot traffic lanes.
