INTELLIGENT DEVICES – “DELIVERING THE PROMISE” For many years, Intelligent Transportation Systems (ITS) have been promising to deliver reduced congestion and safer roads. ITS America has gone so far as to adopt a “zero fatalities, zero avoidable delay” vision for ITS which sets the bar for achievement for the industry. With three recently completed contracts demonstrating innovative solutions to real-world problems, Intelligent Devices, Inc. has contributed to “delivering the promise”. 1. NTCIP Solution to “Where are you, and what are you saying?” Fig 2. – The Portable Sign Problem NTCIP latitude and longitude entered into MapQuest show the trailer location in Buffalo! The Niagara International Transportation Technology Intelligent Devices, Inc solved both The upgrade modules also added Coalition (NITTEC) operates a of these problems. Under a pilot GPS (Geographical Positioning regional ITS system for member project funded jointly by FHWA System) functionality to the signs. agencies out of their Traffic and NITTEC, Intelligent Devices Management Center (TMC) in provided IDI 1320 upgrade The NTCIP objects for latitude and Buffalo, New York.

The In addition, the battery voltage can interface was tested with now be measured from Central The portable signs were not DeviceTester for NTCIP, which using the same NTCIP software integrated into their ITS system for proved that a consistent NTCIP for all signs, irrespective of the two main reasons: interface (with associated brand of the device. functionality) had been achieved 1. The signs were not NTCIP for all four signs. This made these “All and all I feel the pilot project conformant, while their central four trailer signs compatible with was very successful and I and system was.

project, building new regional TMC’s and major fiber optic communication deployment. Florida has made a commitment to the NTCIP standards process, and all new signs deployed in Florida go through a NTCIP testing process. In addition, Florida has committed to NTCIP standards for communication to their camera control systems. The first deployment of the new system is planned for District 6 in Miami. However, a number of different types of signs and cameras are already installed, as part of the existing deployment. Intelligent Devices, Inc was contracted to provide interface modules for signs and two incompatible camera brands, to Fig 4. provide an NTCIP interface Warning Drivers of a Collision Danger Ahead in Tampa. compliant with the Florida Inset: IDI2500 Traffic Congestion Monitor requirement. process, FDOT immediately compare these values to At the same time, Ethernet awarded Intelligent Devices, Inc a thresholds to determine if a network interfaces were provided follow up contract for the upgrade congestion condition exists.
