General Meeting


Hi everyone. Sam Churchill, here, the backup note-taker for Christian. I thought Robert had some interesting things to say about the Intelligent Transportation System and his Sandy Oregon proposal to provide "Smart Jitney" services. The idea is that wireless access points could be used to match riders with drivers. Drivers get a discount on gas. Sandy dropped out of the Tri-Met party, apparently, and has looking into alternative mass transit ideas. Smart Jitney is one.

Here are some (unofficial) notes, links and comments on Bob's presentation:

Tuesday (Oct 30) at the Personal Telco meeting, Robert W. Behnke gave a presentation on the Intelligent Transportation System (ITS). He has proposed a Smart Jitney project in Sandy Oregon. It would let people match a rider and driver and use 802.11b.

Bob has had much experience as an ITS developer and worked with many organizations around the country.

He suggested that here may be synergies with community wireless lans. No specific role for PersonalTelco was mentioned but the possibilities of using 802.11b for this project was described in a general manner. For more information you might write Bob at

As an aside, the FCC allocated a new ITS band at 5.8 GHz. It is ajoining, and just above, the (unlicensed) 802.11a band at 5.8 Ghz.

Manufacturers of commercial wireless lan cards like Atheros were selected for licensed "telematics" applications] in the specially designated 5.850-5.925 GHz band. Atheros AR5000 chipsets were used to test the IEEE 802.11a technology. Those 5 GHz PC Cards are for sale today by Intel and others.


Here are the FCC designated frequencies for 802.11a:

(1) U-NII lower band (100Mhz) (5.15 to 5.25 GHz) - 40mW

(2) U-NII middle band (100Mhz) (5.25 to 5.35 GHz) - 200mW

(3) U-NII upper band (100Mhz) (5.725 to 5.825 GHz) -800mW

(4) Here are the designated FCC frequencies for ITS: (5.850 to 5.925 GHz )


You can see the designated ITS (licensed) frequency ajoins the 802.11a 5.8 band (which stops at 5.825 GHz). The FCC allocated 75 megahertz of spectrum at 5.850-5.925 GHz for the mobile service for use by Dedicated Short Range Communications ("DSRC") systems operating ITS.

It's my understanding that regular IEEE 802.11a wireless lan cards can also be used to carry ITS information. So, perhaps wireless lans and ITS COULD work together in the 5.8 GHz band.

The Federal Highway Administration (FHWA) funded three Research Centers of Excellence (RCEs) to engage in research in ITS technology:

The State of Oregon does not appear to have any effective ITS leadership despite the traffic problems and the high-tech companies located here. BTW, Qsent, located in the Pearl District, has contracts with over 1,000 taxis and limos. They provide pickup services for individuals using WAP phones.

Seattle's BusView system, graphically displays on a website the minute-by-minute locations of buses. It was developed not by, or even on behalf of, the local transit agency, but by a group of students at the University of Washington after they discovered that location information broadcast by buses could be easily intercepted over the Internet. Another University of Washington website,, predicts when the next bus is going to arrive at a given stop. My Bus currently pulls in about 1 million pageviews a month, and gets e-mail from "bus junkies," who sit by the window with a computer to compare predicted and actual arrival times and report discrepancies. The instructor and his students are currently working with the Portland's Tri-Met to come up with an arrival-prediction system that's accurate even in the face of traffic accidents, ice storms, and drawbridge openings.
