PRELIMINARY WARRANTS QUESTIONNAIRE

RAMP METER WARRANT - 2:

Isolated Ramp Meter Deployment

 
     
 

Purpose: This warrant addresses the need for an isolated Ramp Meter deployment that is not part of an overall corridor ramp metering approach.

 

To begin the process of determing if deployment is warranted at your location, please answer the following questions and click the submit button at the bottom of the page.

The preliminary warrants are entirely intended to serve agencies in the operations and maintenance device deployment decision making process. The warrants can also be used to validate existing device deployments.

Step 1: Describe the candidate Ramp Meter location.

Step 2: Answer the following Ramp Meter questions:

1. Does the freeway operate at speeds less than 50 mph for a duration of at least 30 minutes for 200 or more calendar days per year?

3. Will the ramp meter contribute to maintaining a specific level of service (LOS) identified in local transportation plans and policies?
4. Will the ramp meter contribute to maintaining a higher level vehicle occupancy through the use of HOV preferential treatments as identified in the region's transportation system management (TSM) plan?
5. Will the ramp meter contribute to balancing demand and capacity at a system of adjacent ramps entering the same freeway facility?
6. Will the ramp meter mitigate predictable sporadic congestion on isolated sections of freeway because of short peak period loads from special events or from severe peak loads of recreational traffic?
7. Does the Total Mainline-Ramp Design Hour Volume (mainline volume plus ramp volume) exceed the following:
Two mainline lanes in one direction 2,650 vph
Three mainline lanes in one direction 4,250 vph
Four mainline lanes in one direction 5,850 vph
Five mainline lanes in one direction 7,450 vph
Six mainline lanes in one direction 9,050 vph
8. Does the total volume of the sum of traffic in the right most lane and the ramp exceed 2100 vph during the design hour?
9. Are platoons from signalized intersections recognized to adversely impact the ramp in consideration? If hourly volume, based on maximum 30 second volume readings projected to hourly values, exceed 1100 vph (regardless of overall hourly volume)? Note: Overall hourly volume entering from arterials may be relatively low (e.g. 700 vph). However, during periods when platoons arrive, if 30 second readings of volumes represent 1100 vph or greater, this factor is considered met.
10. Do volumes at ramps being considered for meters, within the zone, fall within the range of 240-900 vphpl during peak periods?

 

Step 3: Answer the following survey questions (optional):
Is the device already deployed?
Yes No
Was this form easy to fill out?
Did you have to contact others within your organization to answer the questions?
Were the questions detailed enough?
Exceeded maximum number of characters.
