Select the type of traffic pattern you will need

Single Light: Approach/access is controlled by a single TLD unit

Shuttle: The section controlled by the TLD has one lane for both directions. Traffic flow in one direction is halted while opposing traffic borrows the use of the lane

Two-way: Both approaching and opposing traffic on a 2-way road can be halted in order to safely allow non-traffic activities in the zone controlled by the traffic signals (minimum 2 signal heads).

T-Junction: A junction where three 2-way road segments meet (could also be a Y-junction).

Crossroads: A junction where two (or more) 2-way road segments meet and cross.
