Is Future Mobility Stuck in the Past?<\/strong><\/h3>\n

As we approach Highways UK this year, it\u2019s hard not to reflect on the current trends facing the transport industry. Events this year have been focused how we can deal with the unexpected circumstances 2020 keeps throwing at us, whilst still preparing our networks for future mobility and all the exciting technology that are forming part of the landscape. GLOSA (Green Light Optimized Speed Advisory) is part of what is being shouted about right now, just check out the increase in searches:[\/vc_column_text][vc_empty_space][vc_single_image image=”3921″ img_size=”full”][vc_empty_space][vc_column_text]<\/p>\n

Despite the recent surge in news coverage, GLOSA isn\u2019t anything new. In fact, TRL Software teamed up with TfL for one of the first UK deployments during the Olympics back in 2012<\/a>. GLOSA is simply a small step on the larger journey towards connected and autonomous vehicles, CAV\u2019s. But before this goes too far, first a recap of what GLOSA is all about:<\/p>\n

Definition<\/em><\/strong>: Vehicle system that receives upcoming traffic signal cycle information over V2X communication channels and uses relative vehicle position to compute and display a speed recommendation that, if adopted by the driver, would allow the vehicle to pass the upcoming traffic lights during a green interval, thereby reducing stops at red lights.<\/em><\/p>\n

On the face of it, it\u2019s a relatively simple concept. A limited two-way exchange of information; car and signals, your position, the signal timing and a calculation of the optimal cruise speed to arrive as the lights change to green, avoiding the need to either stop or restart.<\/p>\n

In reality, GLOSA is a lot harder than this for a variety of reasons:<\/p>\n
