Current through Register Vol. 28, No. 5, November 1, 2024

Section 2I.09 - Radio Information Signing

Option:

01 (DE Revision) Radio-Weather Information signs may be used in areas where difficult driving conditions commonly result from weather systems. Radio-Traffic Information (D12-1-DE) signs (see Figure 2I-8) may be used in conjunction with traffic management systems.

01A (DE Revision) A supplemental TRAFFIC ALERT WHEN FLASHING (D12-1P-DE) plaque may be used with the Radio-Traffic Information (D12-1-DE) sign.

Standard:

02 Radio-Weather and Radio-Traffic Information signs shall have a white legend and border on a blue background. Only the numerical indication of the radio frequency shall be used to identify a station broadcasting travel-related weather or traffic information. No more than three frequencies shall be displayed on each sign. Only radio stations whose signal will be of value to the road user and who agree to broadcast either of the following two items shall be identified on Radio-Weather and Radio-Traffic Information signs:

A. Periodic weather warnings at a rate of at least once every 15 minutes during periods of adverse weather; or

B. Driving condition information (affecting the roadway being traveled) at a rate of at least once every 15 minutes, or when required, during periods of adverse traffic conditions, and when supplied by an official agency having jurisdiction.

03 If a station to be considered operates only on a seasonal basis, its signs shall be removed or covered during the off season.

Guidance:

04 The radio station should have a signal strength to adequately broadcast 70 miles along the route. Signs should be spaced as needed for each direction of travel at distances determined by an engineering study. The stations to be included on the signs should be selected in cooperation with the association(s) representing major broadcasting stations in the area to provide:

(1) maximum coverage to all road users on both AM and FM frequencies; and

(2) consideration of 24 hours per day, 7 days per week broadcast capability.

Option:

05 In roadway rest area locations, a smaller sign using a greater number of radio frequencies, but of the same general design, may be used.

Standard:

06 Radio-Weather and Radio-Traffic Information signs installed in rest areas shall be positioned such that they are not visible from the main roadway.

Option:

07 A Channel 9 Monitored (D12-3) sign (see Figure 2I-8) may be installed as needed. Official public agencies or their designees may be displayed as the monitoring agency on the sign.

Standard:

08 Only official public agencies or their designee shall be displayed as the monitoring agency on the Channel 9 Monitored sign.

Option:

09 An EMERGENCY CALL XX (D12-4) sign (see Figure 2I-8), along with the appropriate number to call, may be used for cellular phone communications.

09A (DE Revision) A REPORT DISABLED VEHICLES CALL #77 (D12-4-DE) sign (see Figure 2I-8) may be used for cellular phone communications.

09B (DE Revision) A SIGNAL UNDER STUDY FOR REMOVAL (D12-6-DE) sign (see Figure 2I-8) may be used to inform motorists of the potential removal of an existing traffic signal.
