Arlington County officials will lower prices at some parking meters to encourage more drivers to use those spaces. reports that 180 of the county's 4,800 metered spaces will cost 50 cents an hour, rather than the $1 per hour charged at most spaces. The lower rates will be in effect for six months starting around the end of February. County officials will evaluate whether the lower price was enough to get people to park in the rarely used spaces in areas such as Pentagon City and East Falls Church. - Ben Giles Ben Giles
