Taking Care of Opera House Traffic.
—Special arrangement must be made in large cities in front of opera houses and other places where there are large gatherings.[226] A most difficult problem occurs in New York city between 38th and 41st streets, where several large theaters, opera houses, and halls are located. Mr. Eno suggests that a numbered check be given to the owner of each vehicle with a duplicate to the driver on which are printed directions for lining up to be followed by the driver. As each vehicle comes along the line the number is flashed on a board continuously. Or, a roller blackboard could be used and as each number is rolled out of sight at the top a new number is written in at the bottom. As there might be several lines, at least one for each entrance, there would be several boards and the owner’s ticket would direct which one he is to watch.
