Caltrans activated on-ramp meters at Avalon Blvd onto southbound I-405 in Carson.
Last Friday (5/18) Caltrans set the meters for a ‘green only’ status for the next two weeks to allow motorists to acclimate to the ramp meter signals. On June 1, following the adjustment period, the metering will be fully operational with red and green lights. The ‘green only’ meter status will operate during weekdays throughout the day and early evening from 5:30 am to 8 pm. At other times, the meters will not be active. Motorists are advised that all on-ramp meters allow one vehicle to move per green light.
In anticipation of increased traffic demand, one southbound I-405 on-ramp at Avalon Blvd has been reconstructed and another newly constructed on-ramp has been open to motorists since Nov 2011. The northbound I-405 on-ramp meters at Avalon Blvd are fully active in red and green signal mode.
Ramp metering helps to:
- alleviate constant streams of vehicle flow entering the freeway system that make freeway access difficult for motorists;
- reduce unnecessary weaving that occurs with quick, last minute maneuvers by motorists’ attempts to enter and exit the freeway among steady streams of vehicle flow;
- significantly reduce bottleneck congestion points and controls the overflow of vehicles when demand for freeway space exceeds its capacity.
