Скачать или смотреть Mn/DOT Traffic Report On on Jazz 88.5 KBEM-FM With Bob Jurek August 2018 *MnDOT TRAFFIC RADIO*

Since 1989, Mn/DOT has been partners with Minneapolis Public Schools radio station KBEM-FM Jazz 88 to provide traffic and highway information to drivers in the Twin Cities. This station typically airs jazz but during peak periods or when there is an urgent message to report, live traffic updates from Mn/DOT are provided on this station. This works as an alternative in this region to traditional 10 watt HAR transmitters like other states use. In the Twin Cities metro, a coaxial "leaky cable" Highway Advisory Radio (HAR) transmitter was tried out in the 1980s along I-35W in Richfield MN as part of a pilot project but the department found too many shortcomings with this transmitter so the partnership with KBEM-FM was the solution they found replacing this.

After the partnership was first formed, 25 HAR style signs with wig-wag flashers were placed along the freeways in the Twin Cities to tell motorists "WHEN FLASHING, TRAFFIC INFO TUNE TO 88.5 FM KBEM RADIO". These signs were probably DTMF tone activated. DTMF tones were probably played live over KBEM-FM upon breaking into urgent traffic reports when they wanted to activate these signs. In addition, dynamic message signs could be used as well.

In 2004, there was discussions by Mn/DOT of ending the long standing partnership with the Minneapolis Public Schools due to costs of it and the fact that they implemented the Minnesota 511 travelers information system and other ways of getting real time updates out there. Due to public outcry, the partnership was extended but at a scaled back level. As a result, all the flashing HAR style signs along the freeways were removed due to budget cuts.

At one time audio from KBEM-FM was televised on a cable TV channel operated by Mn/DOT with live traffic camera visual (like what WisDOT/MPTV once did in the Milwaukee area with audio from WPTJ444/WPZK577).
