* Alexandria: Even before the City Council endorsed the COG resolution, Alexandria police were averaging 600 citations a month to traffic light and sign violators. Alexandria officials are alarmed that so many motorists seem to be "pushing yellow." In the first three months, there were 42 accidents related to red light violations, including 17 that resulted in injuries. During the same period last year, there were only 35 accidents related to red lights, including eight that caused injuries.
* Arlington: Police stopped 710 motorists for running red lights between January and March of this year, compared with 999 citations issued for the same offense during a six-month period last year. "We're hoping that the more vigilant we are, the more compliance we'll get," said Cpl. John Haas, a county police spokesman. "We can't be at every intersection all the time."
* Fairfax County: The county is in the midst of a "Respect Red" campaign, and police cited 1,649 violators in April alone. But county police ticketed more motorists in the last 15 days of April than in the first half, so the campaign will continue indefinitely, officials say, until drivers get the message. The worst intersection for red light violations is Reston Avenue and Baron Cameron Avenue, where 100 tickets were written in April. The county does not keep figures on fatalities and injuries caused by red light violations.
* Montgomery County: Police officials don't usually keep separate statistics for red light runners. But they estimate the 4,015 citations issued for the first three months of this year is 40 percent more than the same period a year ago.
* Prince George's County: There are no accident statistics available for the year so far. Last year, five persons died and at least 292 were injured in traffic light-related accidents. Despite the county's relatively high number of deaths and injures caused by traffic signal offenses, county police don't keep separate figures on citations issued to red light violators.
* District of Columbia: Motorists who run red lights frequently complain about illegally parked cars, and D.C. police have become more aggressive about ticketing for parking offenses to help ease traffic bottlenecks. The city, which issued 16,263 red light citations in all of 1984, already has ticketed more than 7,200 red light runners since January.
