Re: Martin Miller’s April 27 letter, “Signal needed for left turn”:

Something had to be done to allow motorists to make a left turn onto Olsen Road after exiting Highway 23 in either direction. Miller is correct that this spot was “an offramp begging for traffic control for years.” However the other letters criticizing the new lights on Olsen Road are also correct. What we now have is a major traffic problem. Traffic is backing up on the freeway, and traffic on Olsen is backed up to the Ronald Reagan Library turnoff.

To rectify the situation, may I propose the following:

— Keep the new signals. It is a fact that left turns from both offramps are safer.

— Bring back the barrier that forced eastbound Olsen Road traffic toward Simi into the left lane as it passed under Highway 23. By returning to the old arrangement, all traffic making a right onto Olsen off the northbound 23 will once again be allowed to do so without stopping. This will remove the backup on the freeway.

— Put up a similar barrier to force westbound traffic toward Thousand Oaks on Olsen into one right lane as it approaches the intersection. This will allow traffic exiting from the northbound 23 to make a left onto Olsen when the light changes. Meanwhile, the traffic in the single right lane can continue without stopping. Once the traffic has gone under the freeway, Olsen can open up to two lanes once again.

This suggestion tries to take the best of both configurations and will keep traffic flowing.
