Because it could and do so safely now; both horse and rider. It sounds like an old joke, but with ELTEC’s focus on specific customer needs, system design helps to keep a precious horse (many valued over $250,000) safe and traffic moving.
From November to May, several communities in Florida become “horse country”; 1000’s or more from around the world winter there. Several communities are “horse focused.” Ancillary businesses thrive in this sector. A McDonald’s has a corral to “park” horses, and has a separate “drive-up window” exclusively for those on horseback.
A Florida community once “trail territory” is now spotted with developments. Riders are leery when a trail crosses a road. In Wellington, Florida ELTEC’s pedestrian crossing system was customized to serve both riders and pedestrians. The horse/ pedestrian crossing includes two sets of push buttons; one at 72-inches allowing the rider to activate the system without dismounting; one at 36-inches for pedestrians and a dismounted rider.
The road is a T configuration. When activated, drivers turning right at the top of the T, do not intersect the horse/pedestrian crossing. But drivers turning left, turn into the crossing, but aren’t able to see the signals on the main road. To ensure a motorist does not turn into a horse and rider or pedestrian, a left turn flashing red arrow alerts the driver to stop before proceeding.
In Loxahatchee, ELTEC’s customized “horse and rider” caution system warns drivers 300 feet before the street is shared with the car. Again the system has the two pedestrian push buttons at different heights. When activated, it flashes for an extended period giving ample time for the horse and rider to clear the 600 foot section of shared roadway.

Solar Powered Work Zone Speed System Developed

In a highway construction zone when a lower speed limit is posted but no workers are present or visible impairment is evident, the lower speed limit looses credibility. Drivers perceive no good reason for slowing down and tend to maintain their speed.
Highway 59 in East Texas is a long term construction project and re-quires a source of reliable information. ELTEC (Electrotechnics Corp) along with the TxDOT office in Atlanta (TX), A-T Communications and the Texas Transportation Institute, developed a solar powered Work Zone Speed System which displays selected speed limits for the appropriate conditions.
When workers are present or hazardous conditions exist, the lighted speed display sign is manually changed by responsible personnel to display the lower speed. It can also be changed by wireless radio. When it’s safe for motorists to drive the normal speed (70 MPH), the sign indicates accordingly. In Texas speeds are reduced at night, so at dusk the system automatically switches to the lower speed of 65 MPH unless the ‘construction zone’ switch is activated and overrides the day/night speed displaying the lower construction speed. The work zone speed is adjustable and set prior to deployment.
The Work Zone Traffic Speed System can be trailer mounted for portability. If the shoulder is too narrow/steep or a more permanent system is required/desired it can be pad mounted as with the four TxDOT units.

CDOT’s “TIGHT CURVES” System Reduces Accidents

States with mountainous terrain frequently have ‘dead man curves’. US Hwy 50 in Colorado has two such curves paral-leling the Arkansas River. In the past, the canyon corridor between mile markers 230-231 averaged three truck rollovers annually. Spillage from the truck’s fuel combined with hazardous cargo took weeks or months to clean up. Cars consistently damaged the guardrail and replacement was frequent. In one area the drop-off is 80 feet. Colorado DOT installed stronger 3-rib, more deeply anchored guardrails, but the hazard still existed.
The issue is speed. CDOT corrected the issue with the instal-lation of a radar monitoring system. Any vehicle approach-ing a curve traveling over 35 MPH activates the blank-out sign to light up with “TIGHT CURVES” followed by flashing “SLOW DOWN”. The sign stays on for 30 seconds. The CDOT Region 5 Traffic Engineer says that since the system was installed in the spring of ’09, only one truck rollover has occurred. Guardrail damage has declined.
On both curves from either direction, the speeding vehicle detection system is installed on each side of the road. East bound the system is solar powered; traveling west it’s tied in to an electrical service. CDOT’s project engineer contacted Chris Mustoe with AM Signal, who provided consultation. AM Signal supplied all the system components.
ELTEC did the solar system sizing to ensure sufficient power for the radar detector and blank-out sign with 10 days of autonomy (fully functional for 10 days without solar charging output).
CDOT will be adding a radar unit to confirm the effectiveness of the system to the FHWA. The additional radar unit will collect the vehicle’s approaching speed (at 1200 ft) and entry speed into the curve (at 200 ft) measuring the vehicle’s deceleration. The data gathered will determined the effectiveness of the warning sign.
