Of course traffic gets worse ("Traffic getting worse? Survey says yes," Feb 25th). Those who study population dynamics in the U.S. know that the Baltimore-Washington area has been growing very rapidly, adding roughly 70,000-90,000 people per year, for quite a few years now. For the Baltimore area, if we consider the population increase of Howard, Anne Arundel, Baltimore and Harford counties (where many car commuters reside), data available show that the population increase for the combined counties since 2000 has averaged 13,000 people per year! The population of Howard County was 25,000 in 1950 and has grown to over 275,000 today.
