A traffic jam can either refer to any traffic light hassler (such as traffic circle), or the specific reaction shown to the right. In this reaction, two traffic lights interact in such a way as to reappear after 25 generations with an extra 6 spaces between them.

Traffic jam oscillators are infinitely extensible. Periods of 0 mod 4, and 2 mod 4 can be made in different ways as long as sparkers exist; in 1994 the known usable sparkers were p4 (mold, T-nosed p4, and heavyweight emulator), p5 (fumarole), and p6 (unix). A period-7 option was added in 1999 as soon as the p7 pipsquirter was discovered. Traffic-jam oscillators provided the first examples of oscillators at periods 102, 104, 110, 112, 126, 140, and 148.

An example of a p102 traffic jam using period-6 corners
(click above to open LifeViewer)
RLE: here Plaintext: here

There are 25 signals in the above p102 traffic-jam oscillator. It takes 25×102=2550 generations for a signal to get back to its original position

The loop can be increased in 50-tick steps by adding pairs of traffic lights, but it's necessary to add traffic lights in sets of six to reach another loop period compatible with the period-6 corners. If the loop is increased to a length of 2700, 25 signals can produce a p108 oscillator if the signals are placed 108 generations apart instead of 102.

An example of a p104 traffic jam using period-4 corners
(click above to open LifeViewer)
RLE: here Plaintext: here

There are 25 signals in the above p104 traffic-jam oscillator. It takes 25×104=2600 generations for a signal to get back to its original position.

Similarly to the "2 mod 4" construction, the loop can be lengthened by adding pairs of traffic lights, but it's necessary to add sets of four traffic lights to maintain a loop length that's compatible with the period-4 corners.

Notice that the line along the bottom edge of this oscillator is slightly oblique, not horizontal. For each pair of traffic lights there is a free choice of two possible relative positions, offset by one cell in one direction or the other. This allows traffic-jam wires to be bent slightly around obstructions, or to be adjusted to make connections as needed.

Corner speed and period

Another option for adjusting the size of the loop by 50 ticks is to replace a "slow" corner with a "fast" corner, or vice versa. Corners can be arranged to send a new traffic-jam reaction off at 90 degrees immediately, then cycle around the other 270 degrees to complete the reset. Or, for the slower option, they can send the reaction around 270 degrees and ignite the perpendicular reaction 50 ticks later than the fast method. This is illustrated by the pattern below.

A period-2100 loop with corners of different speeds and periods
(click above to open LifeViewer)

In order, the traffic-jam reaction passes through pairs of p4 corners, p5 corners, p6 corners, and p7 corners, and then returns to its starting point in 2100 ticks. Most of the pairs of corners consist of a slow corner followed by a fast corner. The two p6 corners are "fast" followed by "slow"; parity constraints prevent the completion of a p2100 loop if the fast corner follows the slow corner for all four pairs.

Stable support

On November 1, 2024, Period1GliderGun found a 25-tick 3-cell traffic light push that releases a glider, used to reduce the period-36 glider gun as 25+11. The next day, iNoMed found that a loaf spin can be used instead of a period-specific sparker. This means that periodic support is no longer needed for either the slow or fast traffic-jam corners, which significantly simplifies the construction of traffic-jam-based circuitry.

An example period-550 capped glider gun showing how a traffic jam can work with stable supports and how a glider can be released using a sparker. Stable options are also known for extracting gliders and inserting new traffic jams into a wire.[1][2]
