New York Engineer Describes 'Psychological' Road Design

Tells Traffic Bureau Students Plan For Safer Highways

Psychological principles must be applied to highway design in order to produce roads on which "the motorist will unconsciously react safely rather than unsafely," Charles M. Noble, Assistant Engineer of the Port of New York Authority told a group of graduate students at the Street Traffic Research Bureau yesterday.

Such a program would involve far more careful investigation of accidents than is practiced now, Noble said, since the standardized police report does not yield information required to deduce the real cause of the accident. He urged tests to determine the suitability of the road to the driver.
