Figure 10 Yellow box at traffic junction
Enforcing yellow box junction traffic rules at intersections improves traffic throughput, reduces congestion and consequentially also carbon emissions.
ETSI 102 704 v1.1.1 [i.7] has reported on the use of radar system for mobile vehicle use, away from roads. Some further examples are provided here of equipment in service.

Figure 12 Crane boom collapse, during container handling operations
Prior to installation of a radar anti-collision system at Southampton docks in the UK, two crane boom collapses occurred. In the most recent, the crane driver received life threatening injuries.
The general market for Crane based radar anti-collision systems has been estimated in ETSI 102 704 v1.1.1 [i.7] and shown in Figure 13. More general applications for the same technology are discussed in the same reference.

Figure 14 Anti-collision system for bulk loader
Bulk loading of Ore is a dangerous process. The noise and dust caused by loading the materials serve to make the drivers of these machines less aware of the relative location of ship and loader. In these conditions, collisions between ship and loader are inevitable, and in some of the larger ports can occur 3 or 4 times a year.
For a 9000 Tonnes per hour machine loading Iron Ore, even a few hours of lost loader time due to a collision can cost over US$ 1m per hour. A recent accident in Queensland Australia saw a loading boom damaged in a collision with the ship; this could not be repaired in situ and a replacement was needed. The total machine down-time was approximately 3 months.
