A box junction in London, pictured from atop the Monument in 1969. A box junction is a road traffic control measure designed to prevent congestion and gridlock at junctions.The surface of the junction is typically marked with a yellow criss-cross grid of diagonal painted lines (or only two lines crossing each other in the box), and vehicles may not enter the area so marked unless their exit ...
Gridlock on a network of two-way streets. The red cars are those causing the gridlock by stopping in the middle of the intersection. Gridlock is a form of traffic congestion where continuous queues of vehicles block an entire network of intersecting streets, bringing traffic in all directions to a complete standstill.
In some jurisdictions (such as New York City), [citation needed] there are ordinances or by-laws against "gridlocking".A motorist entering an intersection (even if on a green light) but unable to proceed and who gets stranded in the intersection (when traffic ahead fails to proceed), and who remains after the light turns red (thus blocking traffic from other directions) may be cited.
Instead of blocking intersections, organizers should have a plan to regroup if riders get separated. Apologies to riders who love big groups, but from a safety perspective it’s not a great idea.

[1] [4] A sign warning motorists to yield to those crossing the crosswalk. Marked crosswalks are usually placed at traffic intersections or crossroads, but are occasionally used at mid-block locations where pedestrian generators are present such as at transit stops, schools, retail, or housing destinations.
Equivalent Circuit Approximation to crossed-dipole bandstop FSS. Fig. 2.4.3-1 shows the comparison in reflection between a single-layer crossed dipole FSS and its fitted equivalent circuit. The equivalent circuit is a series connection of a capacitor and inductor placed in parallel across the transmission line, as in Fig. 2.4.1-2.
A 4-way stop in San Francisco. An all-way stop – also known as a four-way stop (or three-way stop etc. as appropriate) – is a traffic management system which requires vehicles on all the approaches to a road intersection to stop at the intersection before proceeding through it.
