Ordinance:

Chapter 15 – Motor Vehicles and Traffic Section 15‐14 Manual of Uniform Traffic Control Devices ‐ Adopted

• (a) The Manual of Uniform Traffic Control

Devices (MUTCD), a national standard for the use of all signs, signals, markings, and other devices used to regulate, warn, or guide traffic placed on, over, or adjacent to a street, highway, pedestrian facility, or bikeway, is hereby adopted for use within the city.

MUTCD:

Section 4C.01 Studies and Factors for Justifying Traffic Control Signals contains 9 Warrants to aid in justifying a Traffic Signal.

MUTCD Warrants:

• Warrant 1 – Eight‐Hour Vehicular Volume
• Warrant 2 – Four‐Hour Vehicular Volume
• Warrant 3 – Peak Hour
• Warrant 4 – Pedestrian Volume
• Warrant 5 – School Crossing
• Warrant 6 – Coordinated Signal System
• Warrant 7 – Crash Experience
• Warrant 8 – Roadway Network
• Warrant 9 – Intersection Near a Grade

Crossing

• The satisfaction of a traffic signal warrant or

warrants shall not in itself require the installation of a traffic control signal.

• Looked at Warrants 3, 4, and 5.

Warrant 3 – Peak Hour

• Evaluated where the minimum of 1 hour of

an average day, the minor‐street traffic suffers undo delay when entering or crossing the major street. Studied Intersection from 7:22‐8:15 and 3:00 to 4:00.

• a. Total Stop Time exceeds 4 Vehicle Hours in

the one hour period – Not enough data collected to determine.

• b. Minor Street Traffic exceeds 100 vehicles –

Pinson had 173 and 167 respectively.

• c. Total entering volume from major street

has to exceed 650 vehicles – Ark Blvd had 99 and 122 respectively. All three above (a, b, and c) have to be met, since c. was not, the Warrant fails to pass.

Warrant 4, Pedestrian Vol.

• The pedestrian volume signal warrant is

intended for application where the traffic volume on a major street is so heavy that pedestrians experience excessive delay in crossing the major street.

• a. For each of any 4 hours, the number of

pedestrians exceed 107 per hour crossing or a higher number if vehicles per hour on the major street decrease below 1,100. Arkansas Blvd had 8 Children cross from 3:00‐4:00.

• b. This option was for cities with populations

below 10,000 for a 1 hour study having 75 pedestrians per hour and 800 vehicles per hour. Criteria a is not met, the Warrant fails to pass.

Warrant 5, School Crossing

• The School Crossing signal warrant is

intended where the fact that school children cross the major street is the principal reason to consider installing a traffic control signal.

• a. The need for a traffic control signal shall be

considered when the frequency and adequacy of gaps in vehicular traffic stream as related to the number and size of groups

• f school children crossing at an established

school crossing across a major street shows that the number of adequate gaps in the traffic stream during the period is less than the number of minutes in the same period and where there are a minimum of 20 school children during the highest crossing hour. Arkansas Blvd had 8 children cross from 3:00‐ 4:00. Criteria is not met, the Warrant fails to pass.

Traffic Signal Cost:

$30,000 – Old Style Wooden Pole with span wire using existing parts from City Barn with Video Detection and pedestrian

• controls. Would need to add 10%

to cost if awarded for contingencies. $110,000 – Estimate for New Galvanized Pole System. We have not installed any recently, this is an estimate. We did not confirm the Right‐of‐ way needed if awarded.

Recommendations:

• Provide Signed and Marked

Crosswalk west of Pinson to 10’ Trail System.

• Contact School District to see if they

can justify a school crossing guard.

Other Options Not Recommend:

• Stop Signs on Arkansas Blvd. only

approved by MUTCD if Warrant for Traffic Signal is justified.

• Closing Inside Lanes of Arkansas Blvd

and constructing raised median island for pedestrians. A detailed Traffic Engineering Study would be required to justify non‐ recommended options or consider

• ther options.
