LADOT: Installs protected-permissive left-turn signals all directions at BarringtonXWilshire

The Los Angeles Department of Transportation has authorized the installation of protected-permissive* left-turn signals in all directions at Barrington Av and Wilshire Blvd intersection (similar to Bundy Dr and Wilshire Blvd).

At Bundy Dr and Wilshire Blvd intersection, the left-turn signals for all directions are protected-permissive-type*. The left-turn phase for each direction is activated based on demand. In each left-turn lane, the loop detectors activating the left-turn phasing are approximately 70 ft to 90 ft from the crosswalks (depending on the length of the left-turn pocket), so when there are four or more vehicles in a left-turn lane at the beginning of the cycle for that direction, the left-turn phase gets activated and the green phase would be extended if there is a demand.

*In a “permissive” mode, a green signal permits vehicles to turn left as traffic allows(see left image in Figure 1 Permissive and Protected).
In a “permissive/protected” mode, the permissive left-turn phase is immediately followed by an exclusive, protected left-turn phase, initiated by a green arrow signal indication (see image in Figure 1 Permissive and Protected).

An alternative style of a left-turn signal light is Sunnyvale’s
