Smart Motorways?

Transmax's STREAMS Smart Motorways solution is a sophisticated suite of motorway management tools that is enabling road operators to tackle congestion and make people's road journeys safer and more reliable. Transport departments have seen outstanding results using STREAMS Smart Motorways. 

The solution is a comprehensive suite of algorithms that prevent flow breakdown and accidents before they happen. It also provides tools to respond to incidents, if they occur, to get people moving again. 

Transmax’s solution coordinates variable speed signs, ramp signals, dynamic message signs, lane control, and travel time signs that respond in real time to whatever is happening on the motorway.  

How does STREAMS
Smart Motorways work?

STREAMS treats the motorway network as an active system where congestion and incidents can be prevented via the careful control of roadside equipment. It uses sophisticated algorithms to precisely manage the triggers of flow breakdown: vehicle platooning, dynamic formation of bottlenecks, turbulence at merges, clogged exit ramps, phantom shockwaves, poor weather and delayed response to incidents.

Some of these techniques have been used before but Smart Motorways supports a cooperative and strategic approach that manages journeys from end-to-end. STREAMS integrates robust traffic detection, highly advanced dynamic metering algorithms and complementary traffic management components that work together to prevent the breakdown of motorways and improve predictability. 


The cost of congestion cannot be underestimated.

In the U.S. alone, congestion cost $305 billion in 2017,
an increase of $10 billion from 2016*.

STREAMS Smart Motorways is an exceptionally cost-effective investment. 
Reducing congestion on highways means people and goods experience more efficient road journeys,
which in turn supports the economy.
