6.0 Summary of Recommendations

6.5.5 Barrier Gates

Guideline Automatic Lane Barrier Gate Guideline 1
Title Provisions for Automatic Lane Barrier Gates in Toll Plaza Deploying VES Equipment
Text VES equipment should be used in lieu of automatic barrier gates unless vehicle speeds through the automatic lane pose a safety hazard to attendants who must cross more than one lane.
Commentary To avoid the revenue loss from opening the gate for customers who fail to fully pay the displayed toll, plus the operational costs incurred to assure the gate arm raises and to maintain the gates, VES equipment should be deployed instead of automatic barrier gates. The automatic barrier gate installed at the departure end of the toll island to control the flow of traffic through a lane should not be confused with a pedestrian gate installed on the toll island to prevent staff or visitors from walking into a toll lane. This particular gate is rarely automated.

 

Guideline Automatic Lane Barrier Gate Guideline 2
Title Provisions for Automatic Lane Barrier Gates in Toll Plazas with no VES Equipment Deployment
Text Barrier gates should only be deployed in these lanes if both the supervisor’s workstation functionality and an adjacent manual/attended lane toll terminal functionality are capable of remotely raising the gate in the automatic lane.
Commentary None

 

Guideline Automatic Lane Barrier Gate Guideline 3
Title Provisions for Manual/Attended Lane Barrier Gates in Toll Plaza Deploying VES Equipment
Text VES equipment should be used in lieu of barrier gates unless vehicle speeds through the manual/attended lane pose a safety hazard to attendants who must cross the lane.
Commentary None

 

Guideline Automatic Lane Barrier Gate Guideline 4
Title Barrier Gate Horizontal Clearance
Text For toll island installation, the gate cabinet should be setback 12 inches from the face of the toll island or raised barrier.
Commentary None

 

Guideline Automatic Lane Barrier Gate Guideline 5
Title Barrier Gate Arm
Text A ten (10) foot gate arm attached to a breakaway assembly should be specified. The gate arm finish should be striped using two distinct, contrasting colors.
Commentary The 10 foot gate arm minimizes the end gap within the toll lane and maintains good visibility to approaching traffic while compromising gate arm speed, albeit a small reduction.
