Siemens describes the data analytics platform as a “game-changer” for agencies wanting to consolidate units offering different capabilities
Siemens Intelligent Traffic Systems has announced it is making travel time and traffic congestion gathering capability available on its ESCoS roadside unit (RSU). The addition of its new cloud-based Travel Sense application allows RSUs to collect anonymised data from passing vehicles via wi-fi, Bluetooth or DSRC, eliminating the need for additional hardware.
This additional capability now adds to Siemens’ lineup of already-supported CV RSU applications which includes: time-to-change, curve speed warning, variable speed limit, wrong way entry, exit ramp deceleration warning, work zone warning, transit signal priority, emergency vehicle preemption and pedestrian collision warning.
It has an integrated LTE modem for fast backhaul communication and a wi-fi and Bluetooth interface already on board allowing it to connect to the new Travel Sense app, which is powered by Acyclica Go.
According to Siemens, the application gives agencies a pathway for investing in connected vehicle technology without sacrificing current data collection capabilities. In providing this new functionality, the RSU offers a solution for both wi-fi and Bluetooth- based travel time applications and allows for future-proof safety applications using DSRC, said Siemens.
“Determining which technologies will be required long term and which will need to be replaced by connected vehicle technology is ongoing right now and already affecting today’s investment cycles,” said Marcus Welz, president of Siemens Intelligent Traffic Systems in the US.
“Having an all-in-one solution will save our customers costs from purchasing and installing additional equipment while making the infrastructure ready for the advent of self-driving vehicles,” he continued.
“But knowing that our technology is supporting a plethora of applications and is in-sync with all of today’s government efforts to deploy connected vehicles should put our users at ease that they are well-positioned to keep supporting connected vehicles well into the future with our RSUs.”
Siemens claims its RSU is one of the first connected vehicle devices to successfully complete the US Department of Transportation’s most recent round of interoperability testing (for its three national CV Pilot Programs in Wyoming, Tampa Bay and New York City).
One of the most important results of the recent interoperability test was proof that OBUs and the RSU were able to communicate safely and securely using the US DOT-mandated security credential management system (SCMS). Siemens’ said its RSU is one of the few devices that are enrolled in SCMS and one of only a handful of roadside units that meet US Department of Transportation Federal Highway Administration specification version 4.1 for connected vehicle applications using DSRC.
