SwedenThe Swedish Road Administration is rewriting the code for measuring contractor performance to incorporate the use of RT3 technology for grip test measurement. This new requirement will be formally established in September 2009.

Excitement was generated after recent testing in 2008 on Lake Kakel in Arjeplog, Sweden, conducted by the University of Lulea, when the RT3 produced consistently accurate and repeatable results.

JapanThe Civil Engineering Research Institute (CERI), a business affiliated with the Japanese government, is in their third year of RT3 evaluation, now using three of our tow-hitch devices.

Recent discussions in 2008 have led them to consider putting the RT3 on their snowplows.

CanadaThe Ministry of Transportation Ontario (MTO) and the Ministry of Transportation Quebec (MTQ) are in their third year of investigation of using the RT3 for road grip measurement to have a reliable instrument both for measuring contractor performance and road conditions generally.

A turn in the right directionHalliday Technologies is pleased to announce their recent achievement of accreditation by the Federal Airport Authority for runway friction measurement for the RT3. Following a test in 2007 at the NASA tire/friction workshop at the NASA Wallops Flight Facility on Chincoteague Island in Virginia, Halliday’s new water flow rate control system confirmed the accreditation.

Unlike other friction testers, the RT3 was designed for use in winter road maintenance, and therefore is particularly rugged in comparison to other accredited friction testers. A representative of the New York Port Authority was particularly impressed with the large diameter of the tire. This large

diameter allows for easy transportation in deep snow conditions while maintaining consistent and accurate results.

The workshop was attended by manufacturers from several countries including Sweden and Russia, by members of the FAA, and several airport authorities.

The introduction of advanced Bluetooth technology allows for improved communication of runway friction and road grip data to be sent and received via a personal digital assistant (PDA) to a remote secure Web site. This patented system is capable of sending the friction/grip of the surface under the RT3 tire, vehicle speed, steering angle, and the distance the vehicle has traveled since the display was reset.

This cost-effective, non proprietary hard-ware system improves the speed and ease of receiving and interpreting the real-time data.

HistoryDon and Pat Halliday are the founders of Halliday Technologies, Inc. (HTI) an automotive engineering consultant company, established in 1994. In addition to several patented designs in auto related areas, HTI designed and developed the RT3 Device - a breakthrough technology that determines measurable levels of grip between individual tires and the road surface in real time.

2001Ohio DOT contacted Halliday to investigate measuring road grip.

2002/2003Ohio DOT began testing a prototype.

2004Ohio DOT program expanded to include a more diverse and flexible design. Collected 200 days of data.

2005Began real-time data collection to a Web site.

2006The Japanese government found the RT3 measurements successfully compared to the results generated from their dedicated friction bus. The Swedish Road Administration began testing the reliability of the RT3.

2007The RT3 completed runaway friction testing at Wallops using an ASTM 524 smooth tire and E274 water nozzle with a view to FAA accreditation for airport runway use.

2008The Swedish Road Administration successfully compared the RT3 with several other road friction devices available for winter use at Arjeplog, concluding that only devices with the resolution of the RT3 will be used in their protocol for winter maintenance.

2008/2009Ohio DOT conducts specific tests to establish the cost savings when using the RT3 in their winter maintenance program. (continues on page 3)

To the left is an example of the transferred continuous one second PDA data to the Web site. The map shown uses Microsoft MapPoint. Any of the one second data can be read by right clicking on the particular bread crumb - where you can see the friction, distance, speed, and steering. On the bottom left, data is collected in one-second intervals traveling down a major road (green), down several back roads (yellow and red), and over a bridge with very good friction (green).

Soaring Salt CrisisOhio faces a dilemma and a solutionThe average cost of salt has dramatically increased this year from $37.4 per ton in the 2007/2008 winter season, to $50- $150 per ton this winter. This massive price difference is complicating the already complicated process. Many of these complications can be resolved with the RT3, as vehicle operators will be able to disperse the salt only where necessary, resulting in significant savings.

To use Ohio DOT as an example:Salt cost 2007/2008 season = $36.2 million (970,333 ton)Projected 2008/2009 cost = $97.0 million (970,333 ton)Cost of equipment use = $18.9 million (kept same as 2007/2008 season)Staff cost = $19.4 million (kept same as 2007/2008 season)Total projected 2008/2009 winter cost = $135.3 millionThis is a projected $61.8 million increase from last year alone!

Knowledge of the friction readings across the state allows managers to organize their fleet more like a fire chief does his operation i.e. identify the need, treat as required, and bring in trucks when the meters record good levels of friction, saving on overhead costs as well as product.

Considering the current large variations experienced in salt deployment across the state from county to county (573%) and frequency of plowing (320%), it is conservative to say that at least a 20% saving on total salt used can be achieved when 50% of vehicles use the RT3.

With a projected $1 million annual maintainence cost, the RT3 can save ODOT approximately $18 million every year!

RT3 benefitsBecause of the small slip angle used in the RT3, the energy loss at the contact patch of the tire is very low (unlike many other friction testers) and the resolution of force measurement at the hub is very high; therefore, the RT3 can be driven over high friction surfaces continuously without the need for the addition of a water film to keep the ASTM test tire rubber within acceptable limits of use.

This unique aspect allows the RT3 to be used on any runway surface (without the addition of water), at any temperature, and for any driven test distance without there being any negative data output due to tire overheating. This quality allows the RT3 to be used to measure the real surface conditions that may exist at any time without the addition of water, which changes the true surface friction value.

With grip data you can: 1.) Coordinate winter maintenance response and vehicle deployment - quick response leading to fewer accidents. 2.) Measure grip levels to help determine when to start and stop treatment and modulate amount of product used during treatment. 3.) Measure effectiveness of total treatment processes. 4.) Ensure safer operation of winter maintenance vehicles. 5.) Minimize damage to infrastructure and environment through more efficient product use. 6.) Evaluate levels of maintenance performance. 7.) Communicate deteriorating conditions to the driving public.

We are convinced that integrating the RT3™ into our winter maintenance program will allow us to make significant progress in the efficient deployment of our resources. With the RT3™ we are able to map and observe real-time friction conditions around two of our main cities, Columbus and Cleveland, during winter events. Because of this data we are investigating ways of indicating to the public when dangerous road conditions exist.” -Ohio Department of Transportation

Swedish NewsThe RT3 is on its way to becoming the standard in grip measurement and increased road safety in Sweden, as all manufacturers must receive accreditation from the SRA with our device to be designated and sold as a winter tire, suitable for winter use.

Recent testing of Volvo cars and SUVs was done with a variety of different manufacturers’ tires. Only some of the tires passed the test on Lake Kakel, Sweden, with the RT3 being the only device measuring the grip value.

2009HTI announces the breakthrough technology which allows the transmission of real time friction data from the RT3 to be transmitted to a remote web page via a Bluetooth connection to a PDA.

HTI currently works with the Ohio DOT, the Swedish Road Administration, The Civil Engineering Research Institute in Japan, and both the Ministry of Transportation Ontario and the Ministry of Transportation Quebec in Canada. They also have a presence in several other states.

Above is a PDA display receiving information describing the instantaneous roadway grip measuring in real-time by the RT3.

Bluetooth PDA technologyIndependent of runway condition, vehicle speed, and water delivery system, the PDA RT3 display and MapPoint breadcrumb trail will show the following colors, representing the following friction values:

Red Friction value 0.00 to 0.50 (0 to 50) Yellow Friction value 0.52 to 0.70 (52 to 70) Green Friction value 0.72+ (72 to 100)

Data is transmitted via the cell phone system to a remote site; the PDA also stores all of the one second information on the microSD. This one second calculated information records distance, friction, vehicle speed, and vehicle steering angle. Additionally, the MapPoint breadcrumb display indicates GPS position and vehicle heading. In this system, no laptop or inverter is required in the vehicle.

If you ever ask these questions: StrategiesHow can we indicate changing road conditions to the public? Are our plows always in the right place at the right time? Do I know how effective anti-icing treatment has been? Can I take the guesswork out of when to start de-icing? Do my operators know when to stop applying product? How can I optimize the use of my staff & equipment? Can we measure the level of service of our subcontractors?

EfficiencyAre operators deploying the correct amount of product? Are we using the most effective anti/de-icing product? Do the operators really know how slippery the road is? Did the maintenance process start and end at the right time? Is enough de-icing product deployed where it’s needed? Is too much product deployed during an event? Are plows on the road when/where it is not necessary? How can I help inexperienced operators do a good job? Is there a way to show how effectively and efficiently we deal with winter events?

your solution is the RT3.

Several tow hitch RT3 units on a variety of vehicles used during testing in 2008 on Lake Kakel in Arjeplog, Sweden. The tests were conducted by the Swedish Road Administration to complete investigative work using the RT3.
