147 Vitronic is showing off two of its latest lines of dynamic messaging signs at ITS America Pittsburgh, highlighting the growing diversity of its product line for customers who are finding more applications for displaying multiple messages on demand.

The company’s Mobility line are custom-built dual message signs created with strings of LED lights. The signs can be designed for any size and color and can be tied to road sensors to determine the appropriate message to display. Phil Perut, president of SES America, said the signs are cost-efficient option for applications that require two messages rather than an expensive full-color LED display board. Perut cited an example of a weigh-in-motion application planned in Georgia. As trucks trigger a sensor in the road, a sign indicates a right or left turn depending on the weight of the vehicle.

The company’s DMS Connect signs are connected to the cloud to display travel times in real time. Traditionally, traffic information is captured by road-side sensors and sent to a central traffic control center where travel times are calculated. The information then has to be transmitted back to the signs.

Connecting signs directly to the cloud allows travel times to be captured from travel time providers such as Google and TomTom, eliminating the need for dedicated road sensors and networking equipment. Flexibility is also achieved by allowing engineers to change routes remotely—as long as the travel time provider has that capability—while traditional systems are limited to routes where sensors are deployed.

“Virtually the entire world is covered,” said Perut. “You can convey travel time to drivers on arterial roads or in small towns. It’s like having an app deployed directly on the signs.”

    SES America (SESA) and contractor partner Traffic Control Devices has completed final commissioning of walk-in dynamic message signs (DMS) for the Harris County Toll Road Authority along Interstate 10 and US 225 to enhance travel time information and alternative routing advice. SESA manufactured an energy efficient LED display, the Messenger 6000, requiring no ventilation or cooling systems, dramatically lessening maintenance and labour costs.

    New trials show Bluetooth and Wi-Fi signals can be reliably used for measuring travel times and at a lower cost than an ANPR system, but which is the better proposition depends on many factors. Measuring travel times has traditionally relied automatic number plate (or licence plate) recognition (ANPR/ALPR) cameras capturing the progress of vehicles travelling along a pre-defined route. Such systems also have the benefit of being able to count passing traffic and have become a vital tool in dealing with c
