Smart Roads

PrismaRoad, Prisma’s next-generation solution for smart roads, uses its patented Hyper-Scan Fiber-Sensing™ technology enabling

ultra-sensitive and intelligent-learning detection to provide real-time intelligence and uniquely reliable monitoring capabilities.

PrismaRoad, Prisma’s next-generation solution for smart roads

The solution lowers deployment costs by using standard, pre-deployed fiber-optic cables (including cables installed within conduits or concrete ditches). These fiber-optic cables, which are installed as part of most modern infrastructures, operate as the system’s “sensors” and enables PrismaRoad to continuously monitor the road and provide alerts regarding accidents, vehicles traveling at high speeds, traffic jams, and many other high-value indications for up to 100 km per PrismaRoad unit or 200 km per dual-unit.

PrismaRoad identifies the acoustic signature of each event at or near the road, at a resolution that allows classification of the events and identification of their location with unprecedented accuracy and drastically reduces the “noise” of false positive and negative alarms. 

Within a distance from the road that you pre-define, PrismaRoad allows smarter, faster road management and prevents criminal or malicious activity by flagging for classification a range of events that can include:

  • Accident detection

  • “Car on the shoulder” alert

  • Car speeding alert

  • Average speed of traffic

  • Congestion

  • Traffic at a standstill

  • Journey time between defined locations

  • Vehicle count flow

  • Volume estimate

  • Jaywalkers

  • Suspicious activities such as theft or vandalism of telecommunication cabinets 

  • Rockfall and landslide events

Solution Architecture

PrismaRoad’s platform is Plug & Play – with zero infrastructure installation, and minimal maintenance. 

 

The platform provides monitoring for up to 100 km per PrismaRoad unit or 200 km per dual-unit. The unit is connected to a single Command & Control (C&C) unit located in the customer’s operating center. 

The PrismaRoad unit attaches directly to the customer’s fiber-optic cable with a simplex SC/APC connector, which connects to a single fiber in the patch panel – ensuring access to a single fiber only, i.e., not compromising the activity or security of any other fibers in the cable. An Internet connection (LAN or WiFi) is required to transmit the monitored data to a C&C unit. 

Scaling up involves use of multiple PrismaRoad units, each of which provides coverage for up to 100 km. Each unit is located in a communication room. All of the units combined require a single C&C unit in the customer’s operating center.

 

There is no need for discrete sensors. Upgrades are software based; no hardware upgrades are required.

Key Features & Benefits

Systems involving thousands of sensors along the road are expensive for deployment, operation, and maintenance.

The alternative is fiber sensing - using very long fibers as sensors - which is probably the most cost-effective solution. But before PrismaRoad, existing solutions were ineffective due to high false alarm rates, poor target classification, and limited ability to use pre-deployed optical communication cables as "sensors".  

PrismaRoad solves solves all of all these issues thanks to its revolutionary Hyper-Scan technology, which offers 100x sensitivity improvement over alternative systems.

 

PrismaRoad has raw data of unparalleled quality. We apply Big Data techniques to data sets that are several orders of magnitude wider, with significantly higher SNR (signal-to-noise ratio) levels – leading to very high detection probability and advanced target classification. 

 

Upgrades to the system, including the addition of new features and capabilities, involve software solutions that are installed remotely.

All Information Consolidated in a Single Location & Single Display

The C&C unit presents the consolidated data of multiple units, with a real-time map and detection table that displays the following information:

  • Detection of events

  • Classification of events

  • Location of events (at a resolution of less than 10 m)

  • Identification of multiple, simultaneous events without interference or crosstalk
