Via NBC 4:
Traffic officers will begin directing rush hour traffic at 38 of the city’s most heavily congested intersections, Los Angeles Mayor Antonio Villaraigosa announced Friday.
About 50 officers will attempt to control traffic, assist pedestrians, assess the waiting time for traffic signals and maintain order at intersections from 7 a.m. to 9 a.m. and 4 p.m. to 6 p.m. weekdays, Villaraigosa said.
About half the intersections are reportedly in the San Fernando Valley. …
The city’s Department of Transportation conducted a seven-month pilot project at 40 intersections and found that delays were reduced by 20 percent when an officer was present.
The pilot project also showed that for every $1 invested in sending a traffic officer to a busy intersection, the average motorist saved $4 in travel costs.
I find it interesting that technology has apparently failed in keeping traffic moving (sensors in the road, et al), so the fallback option is now being called upon to help reduce these traffic jams.
