THE COMMITTEE DEFINES "TRAFFICWAY", RECOMMENDS THE UTILIZATION OF SIX-WHEEL TRUCK, ENDORSES THE ADOPTION OF STANDARD ACCIDENT REPORT FORMS AND URGES THE DEVELOPMENT OF HIGHWAY PLANNING IN METROPOLITAN REGIONAL AREAS. A DISCUSSION OF "UNSAFE CARS" TAKEN FROM A BULLETIN OF THE CONNECTICUT HIGHWAY DEPARTMENT IS PRESENTED. DATA OBTAINED BY THE USE OF THE TRAFFIC FLOW RECORDER DESCRIBED BY DR. MCKAY IN THE SEVENTH PROCEEDINGS HAVE BEEN SUPPLEMENTED BY RECORDS OBTAINED WITH A MECHANICAL RECORDER WHICH PRINTS ON A MOVING TAPE THE ACTUAL SPEED OF MOVEMENT WHEN THE CAR IS IN OPERATION, THUS SHOWING THE EXACT HISTORY OF AN ENTIRE TRIP OVER A ROAD OR STREET. USING THESE RECORDS TOGETHER WITH TRAFFIC VOLUME DATA SOME RELATIONS BETWEEN SPEED, CAPACITY AND ROADWAY WIDTHS WERE WORKED OUT. CONCLUSIONS OF THE COMMITTEE CONCERNING ROADWAY WIDTH AND TRAFFIC CAPACITY ARE PRESENTED. THE MOTOR VEHICLE ACCIDENT RECORDS OF THE PENNSYLVANIA DEPARTMENT OF HIGHWAYS ARE ANALYZED WITH RESPECT TO: RELATION OF OCCURRENCE TO TIME OF YEAR, DAY OF WEEK AND TIME OF DAY; SAFETY ON RURAL ROADS AS COMPARED WITH URBAN ROADS; SAFETY OF IMPROVED ROADS COMPARED WITH LIGHTLY OR UNIMPROVED ROADS AND EFFECT OF PHYSICAL CONDITION OF ROAD ON RECURRENCE OF ACCIDENTS.
