ELTEC’s Rectangular Rapid Flashing Beacon (RRFB) light bars comply with the Federal Highway Administration’s (FHWA) approval for optional use at uncontrolled pedestrian and school crossings.

Studies show using RRFB signals significantly increases motorist compliance to “yield to pedestrians” (80-95%) compared to (15-20%) with standard flashing beacons. Systems are pedestrian activated: push button or passive detection.

As required by the FHWA, the Class 1 RRFB (used by police & emergency vehicles) is a rectangular shaped, high intensity light head. The flash pattern provides direct, ultra bright concentration as well as wide-angle intensity.

ELTEC has designed two styles of RRFB light bars:

• One-sided with 2 RRFB’s: Used with divided highways with a medium or one-way streets. Mounts to tapered, wooden, or standard 4 ½” O.D. pole or other diameter pole sizes where banding is appropriate.

• Two-sided wraparound with 4 RRFB’s: Used with two-way streets or medians. Mounts to either a 2 ⅜” or 4 ½” O.D.

pole, or 2 1/4” Telespar.

Each style has recessed signals to minimize vandalism and can include one or two end-mounted signals for pedestrian verification. Two finishes are standard: Federal Yellow or brushed aluminum. Custom colors are available.

Both light bars can be retrofitted to existing pedestrian crossings currently using round flashing beacons. The RRFB light bar works with either DC (solar) or AC systems. All solar powered systems are sized for each project taking into consideration the average number of crossings per day (hours of operation), latitude, local site conditions, and weather ensuring sufficient power during winter months. Duration of flash time is user defined.

• Significantly increases motorist compliance to yield to pedestrians (approx. 80%–95%) compared to standard beacons (15%–20% range)

• Flash pattern choices: 2 / 4-1 or WW+S – recommended

• Lab certified Class 1 light intensity

• Optional: pedestrian verification signal

• Federal Yellow or brushed aluminum; Custom colors available

ELTEC Comments – ODOT Traffic Engineering Manual Plan Note 242-8 Solar Powered Rectangular Rapid Flashing Beacon (RRFB)

In general, Eltec will comply with all requirements as delineated in the ODOT Traffic Engineering Manual with comments/exceptions as noted below. In general:

1. There is no specification as to the number of crossings to be expected. While the manual specifies a 40 ampere hour battery minimum and a 55 watt solar panel minimum, there is no way to validate sizing without knowing the number of crossings. Eltec has assumed 300 crossings per day.

2. No location for the system was identified. Geography can affect the required solar panel size. Eltec assumed the worst location in Ohio for its system sizing – Toledo

OH.

3. The Engineering Manual does not require a solar sizing report to support the vendor’s system design. Eltec recommends this and has followed its recommendation by including its solar sizing report.

4. The requirement for 30 days autonomy is an unreasonable requirement. Consider that a load of 4 RRFB LEDs running for just 1 hour per day at 5 watts each consume 10 watts of power or approximately 1 ampere hour per day. For 300 crossings this is almost 2 ampere hours per day. Adding to this is the optional pedestrian light and the system will consume approximately 2.5 ampere hours per day. Most radios consume 100 milliamps or in a 24 hour period, the load is 2.4 amps per day. Thus the total load is approximately 5 ampere hours per day. Thus 30 days of autonomy requires a battery capacity of 150 ampere hours. Even if one assumes that the load 70% or 3.5 ampere hours per day, the battery capacity required for 30 days of autonomy is 105 ampere hours. Further the useful capacity of a battery is approximately 70% of its rated capacity, thus in the first example the battery array would have to be over 200 ampere hours to provide 30 days autonomy. In the second example the battery array would have to be 150 ampere hours to provide 30 days of autonomy. There is one other way to get 30 days of autonomy and that is to have the system do daytime dimming. This is not allowed by FHWA letter of interpretation dated Sept 27, 2012. The system that Eltec provides will have 10.6 days of battery autonomy with a 55 ampere hour battery. As can be seen from the sizing report, this system also provides a 0.0% probability of loss of load throughout the year.

5. The solar panel is a 50 watt solar panel per the attached sizing report for the Toledo Ohio area, the worst location in Ohio.

Interpretations of NSOL System Summary Report

Site Summary: This is generally the location where the solar system is being installed. In some instances it applies state wide as the location selected represents the worst location in the state for sunlight.

Load Summary: Load summary is the system calculated load based on load (either in terms of watts or amps) and the duration. Load summary is the total load that is supplied by the system in a 24 hour period.

System Summary: System summary identifies the type of solar panel along with its power ratings, the number of solar panels (# in series/# in parallel) (usually 1 and 1) and the battery bank. The battery bank may be slightly confusing as it identifies the number of cells in series (6 for a 12 volt battery). The number in parallel is the number of 6 series cell batteries in parallel. Thus 2 for # in parallel mean 2 12V batteries in parallel. If # in series was 12 and number in parallel was 2, you would have a 24 volts system with 2 batteries in series. Thus you would have a total of 4 batteries in the cabinet.

Insolation: The amount of solar radiation that the panel sees during a typical day. The report shows the radiation in kWh/m2/d. It uses this value in its algorithm to calculate the array output for a typical day. Obviously for an overcast day, the output will be less.

Array (Ah/day): This column provides the typical power generation that can be expected on a clear day. The larger this value, the more sun/fewer clouds expected to be experienced. Typically coast lines produce have more cloudy days.

Sys Losses: Generally we use 10% for internal system losses.

Load (Ah/day): This column shows the load that the system calculates for a typical day during the month. Obvious.ly for flashing beacon loads that operate 24/7 the load will be different each month as the length of daylight/darkness varies from month to month.

Batt Size (days): This column is the calculated days of battery autonomy. Battery autonomy is defined as the time that the system can operate just from the battery without any recharging of the battery. The lower the array to load ratio (ALR), the higher the battery autonomy should be. The higher the ALR, the lower the battery autonomy can be.

Avg BSOC: This column is the average battery state of charge. The higher the percentage, the less the battery gets cycled, the longer the battery life. Typically 90% or higher is a good number.

LOLP: This column is the loss of load probability. Loss of load means the system goes dark for flashing beacons or the equipment loses power for other devices. This number should always be

0.0%. Power management means that power to the loads is being reduced throughout the operation of the equipment. This is typically achieved by dimming flashing beacons.

ELTEC RRFB

ssours Typewritten Text

On December 21, 2017 the Federal Highway Administration (FHWA) announced the termination of the Interim Approval of the Rectangular Rapid Flashing Beacons (RRFB) (IA-11). The FHWA prohibits the use of patented devices and learned there were several patents on the RRFB device. This was a blow to the Traffic Safety Industry as studies have proven that the RRFB was more effective than standard round beacons in driver yield rates (approx. 80%-95%).

In March, a third-party company purchased and then disclaimed all patents which had restricted federal approval of the RRFB system. The FHWA immediately issued a new interim approval IA-21 in the Manual of Uniform Traffic Control Devises (MUTCD) and the Rectangular Rapid Flashing Beacons (RRFB’s) again became authorized.

ELTEC’s RRFB is fully compliant with IA-21 and can work with either DC (solar) or AC systems. Our solar powered system is sized for each project taking into consideration the average number of crossings per day, latitude, local site conditions, and weather ensuring sufficient power during winter months.

There are a few differences that must be noted from the approval of the IA-11 and the IA-21.

The first important thing to note is that if you have an RRFB unit installed under the IA-11 approval, it may remain in use until the end of its useful serviceable life.

All states and local agencies must apply for new approval under IA-21.

Only one flash pattern is permitted, the wig-wag+simultaneous (WW+S). ELTEC has used this approved pattern in its RRFB systems since 2015.

Night time dimming is recommended For beacon operation, R10-25 signage explaining the purpose and use of the pedestrian pushbutton detector MUST accompany the pushbuttons.

For accessible pedestrians, vibrotactile indications or percussive indications CAN NOT be used.

A locator tone or voice message saying: “Yellow lights are flashing”, spoken twice is permitted.

If your ELTEC RRFB was purchased prior to January of 2015, a device kit is available for purchase to update the system to meet new flash requirements.
