Edward F. Kearney, 67, a lawyer who specialized in traffic tickets and an expert in bicycle safety, died Aug. 8 at home in Washington. He had myelofibrosis, a blood disorder.

Mr. Kearney was born in New York and graduated from Union College. He came to Washington for law school and he graduated from Georgetown University Law Center.

For 20 years, Mr. Kearney was executive director of the National Committee on Uniform Traffic Laws and Ordinances. In this role he helped draft the vehicle code on which most traffic laws are based. He also lectured traffic court judges.

He established his own traffic law practice in 1984, and he handled as many as 50 traffic tickets a day at the D.C. Bureau of Traffic Adjudication. Most of his clients were taxicab drivers. He testified frequently before the D.C. City Council on issues related to the D.C. Taxicab commission and on traffic law enforcement.

He helped prepare legal documents establishing the Washington Performing Arts Society, which was founded by his father, Patrick Hayes, who died last year.

Mr. Kearney was a bicycle commuter and expert in bicycle safety. He had testified in product liability cases involving night accidents, and he designed, manufactured and marketed bicycle lights for night riding.

He had done volunteer legal work for the Washington Area Bicyclists Association and the League of American Wheelmen.
