PRELIMINARY WARRANTS QUESTIONNAIRE

RAMP METER WARRANT - 1:

Corridor-wide Ramp Meter Deployment

Purpose: This warrant addresses the need for a 'zone' of Ramp Meters along a stretch of freeway (typically considered in 3-6 mile segmets).

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.
Exceeded maximum number of characters.

Step 2: Answer the following Ramp Meter questions:

1. During the AM or PM Peak Period, does the zone in consideration have at least 30 minutes per commute day (measured in 5 minute increments) where the demand is equal to or exceeds 95% of the downstream capacity, according to the following equation:

MV + OR > (ER + MC)*.95

MV=	Upstream Mainline Volume (in veh/5 minutes)
OR=	The sum of On-Ramp volumes of ramps within the zone (in veh/5 minutes)
ER=	The sum of Exit Ramp Volumes within the zone (in veh/5 minutes)
MC=	Downstream Mainline Capacity (in veh/5 minutes)

Yes No

2. Are platoons from signalized intersections recognized to adversely impact ALL on-ramps feeding the freeway segment under consideration? For example, if hourly volume, based on maximum 30 second volume readings projected to hourly volumes, exceed 1100 vph. (regardless of overall hourly volume).

Yes No

3. Is there one or multiple area(s) within the zone where crashes are understood to exceed the typical crash rate (at the ramp gore point or within 500 feet in either direction of the gore point) for the metropolitan area?

Yes No

4. Do volumes at ramps being considered for meters, within the zone, fall within the range of 240 - 900 vphpl during peak periods?

Yes No

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