Vehicular and pedestrian traffic in and about the north central campus of the University of Michigan was surveyed in November 1964 to obtain the traffic and parking data necessary to establish the basic characteristics of vehicular movement and to provide a basis for recommendations to improve area traffic circulation. The report recommends reduction of through traffic volume through improvement of circumferential thoroughfares, pedestrian bridges over high volume streets, widening of streets, elimination of on-street parking, and the closure of some streets to vehicular traffic. Appendices include sample data collection sheets, trip tables, term definitions, and data summaries. (RLP)
