block stops. There are few streets over which street cars are operated that are wide enough for the street-car lane, a lane for moving vehicles, and a space for parking. The usual condition is that the moving vehicles must use the car-track space, since the other lane is used for parked vehicles. Just one parked vehicle per city block will keep the outside lane from being used by moving vehicles. In Indianapolis, parking has been prohibited during the hours of peak loads on several streets having car lines. These restrictions have definitely aided the street-car operation and made the service more comfortable and rapid. There are fewer accidents between moving vehicles and street cars and between moving vehicles and parked vehicles than before the regulations were established. These regulations should be established by ordinance and so worded that stopping and parking would be prohibited during the hours of peak loads. Parking regulations must be enforced by arrests in order to get the proper observance by the drivers. Signs alone will not get results. The enforcement of the regulations must be uniform and continuous and impartially imposed by the police and the courts. These regulations restricting parking are necessary in order that the streets may be used for their prime purpose, that of providing an unobstructed way for moving vehicles. We all demand an open way for the vehicle in which we are pass­ engers, but when we reach our destination, we, like all others, expect to use the street for parking. Traffic engineers, construction engineers, and civic leaders have a big job ahead in educating the people to the need and construction of off-street parking facilities. It is not always an easy job to establish and enforce parking regulations, but during the present war times everything possible should be done to expedite the movement of mass transport vehicles and vehicles to war industries. 116 PURDUE ENGINEERING EXTENSION DEPARTMENT
