To begin I havent saw the content of your currciulum so I do not know if this is something you may have learned
* LANE=ROAD/STREET or what ever you like to call it*
Option One: Replace Intersections all together with round-a-bouts or aka the circular intersection. Round-abouts are far more safer and forgiving, when you go into the intersection you dont have to comit to the move, thus eliminating one of the main reasons people make accidents at intersections: accidently going into an intersection, realizing their mistake, and out of panic crash into other cars trying to get out. As an added bonus round a bouts do not require traffic lights are far mor visually apealing. Furthermore, rounfd abouts eliminate the confusion of traffic lights something that also causes accidents at itersections.
Option two: In America at an intersection, the system works by lanes taking turns of which lane has cars moving into them. This alows for cars to move into lanes with other cars in their blind spot a huge contributor to accidents. A solution to this is changing how the system works. Instead of lanes taking to turns to allow cars to flow into their lane, the lane takes turns letting cars out of their lane. As a result only one lane has cars moving out of it making it much safer by eliminating the blind spot dillema and making the actual lane/road change in the intersection itselft less crowded and safer as a result. However, this sacrifices the speed at the intersection making the process slightly slower.
