Current through December 3, 2024

Section 290-RICR-20-00-3.7 - Performance Criteria

A. The Technical specifications for any Automated traffic violation monitoring system to be installed on roadways within the State of Rhode Island must demonstrate that the system operates consistent with the criteria specified herein.

B. At a minimum, Automated traffic violation monitoring systems must:

1. Provide a recorded image that clearly depicts both:

a. A Traffic signal displaying a red indication, and

b. A vehicle approaching the stop line of an intersection while the Traffic signal displays a red indication.

2. Provide a recorded image that clearly depicts both:

a. A Traffic signal displaying a red indication, and

b. A vehicle traveling beyond the stop line of an intersection while the Traffic signal displays a red indication.

3. Provide a recorded image that clearly and discernibly depicts the rear license plate information for a vehicle that has traveled beyond the stop line of an intersection during a red indication. This recorded image may be derived from either image required in §§ 3.7(B)(1) or (2) of this Part, above.

4. Provide a minimum delay or "grace" time (enforcement threshold) of 0.2 seconds before photographing the violating vehicle.

5. Include a data bar in each recorded image that discloses:

a. The month, day, and year that the image was recorded;

b. the actual time that the image was recorded, using military time and carried out to the tenth of a second (00:00);

c. the location where the image was recorded, described either in words or using a unique location code number;

d. the lane number where the traffic signal violation occurred;

e. the actual yellow time for the traffic signal where the image was recorded, displayed in seconds a carried out to the tenth of a second (00:00); and

f. the delay or "grace" time (enforcement threshold) displayed in seconds and carried out to the tenth of a second (00:00).

g. Data bars embedded in the recorded image pursuant to § 3.7(B)(2) of this Part, above, must also disclose:

(1) The time elapsed between the image required in § 3.7(B)(1) of this Part and the image required in § 3.7(B)(2) of this Part, above; and

(2) the time elapsed-taken directly from the traffic signal controller and displayed in seconds and carried out to the tenth of a second (00:00)-between the beginning of the red indication and the actual time that the image required in § 3.7(B)(2) of this Part, above, was recorded.

6. Verify and state that the yellow time for the Traffic signal where images are being recorded conforms to the Engineering study submitted for that intersection.

7. Demonstrate the ability to achieve a minimum efficiency standard of seventy (70) citations issued for every one hundred (100) violations captured, or seventy percent (70%).

C. Once the Department evaluates the Technical specifications for a particular automated traffic violation monitoring system and determines that the system operates consistent with the criteria specified above, the Department will include that particular system on its approved list.
