Closed Circuit Television (CCTV) - Questionnaire
IS A CCTV WARRANTED?
Five (5) warrants have been identified to capture the most common uses of Closed Circuit
Television (CCTV). While there are other purposes and uses for CCTV, the warrants developed
to date have focused on the following five.
Please select a warrant below most similar to your application. To then determine if a CCTV is
warranted for your application, please fill out the appropriate questionnaire on the following
pages for the warrant you selected and email the completed questionnaire to
[email protected] or fax to 503.210.1154.
CCTV Warrant - 1:
Traffic Observation (see page 3)
Purpose: To visually observe traffic conditions in order to determine if
alternate signal timings are appropriate (either to flush special event
traffic or to commuter traffic by manually implementing time of day flush
plans).
CCTV Warrant - 2:
Traffic Verification (see page 5)
Purpose: To allow traffic operations personnel or emergency response
teams to visually verify traffic flow and/or incidents (e.g. crashes, debris in
roadway) in order to activate or dispatch appropriate response and post
message to traveler information systems.
CCTV Warrant - 3:
Weather Verification (see page 7)
Purpose: To allow maintenance dispatchers and traffic control personnel
to verify weather conditions on the roadway, either to guide traveler
information dissemination or to dispatch snow removal and treatment
operations.
CCTV Warrant - 4:
Traveler Information (see page 9)
Purpose: To allow travelers to understand traffic delay and road weather
conditions by viewing images of the roadway from the Internet prior to
departing.
CCTV Warrant - 5:
Field Device Verification (see page 11)
Purpose: To allow traffic or maintenance operations personnel to verify
operational functionality of in-field devices (such as Dynamic Message
Signs, road/lane closure gates, and other devices).

Purpose: To visually observe traffic conditions in order to determine if alternate signal timings
are appropriate (either to flush special event traffic or to commuter traffic by manually
implementing time of day flush plans).
Please answer the following questions.
CCTV Questions
Describe the candidate CCTV location.
1. Are there typically periods of time at least twice per week of ‘loaded’ cycles (i.e. where
the vehicles in the queue do not all dissipate in one green cycle) that last 15 minutes or
longer?
2. Does the signalized intersection have significant cross street traffic such that visual
observation is needed before flushing the primary route (i.e. in order to verify that the
secondary street is not backing up)?
3. Do pre-timed flush plans exist and would local policy only allow implementation of flush
timing plans with visual observation verifying the need?
Yes
No
Yes
No
Yes
No
Is a CCTV Warranted for your application?

2a. Do the incidents and events that occur on freeways typically cause delay to travelers of at
least 15 minutes while the incident is active and has not been cleared?
Yes
No
2b. Do the incidents and events that occur on arterials typically cause impact travel such that
the signal progression is no longer occurring and vehicles are not clearing green cycles?
Yes
No
3. Do the peak hour volume for the route(s) visible by the camera exceed 4000 vehicles per
hour for freeways or 2000 vehicles per hour for arterials?
Yes
No
