A description is presented of a two lane rural highway in Maine which has been equipped with a complex instrumentation system to record driver problems in discrimination, judgement and vehicle control. The system consists of portable vehicle detection stations, nodes of vehicle-sensing loops installed in the pavement, and vehicle receiver-display units. The instruments are connected to a computer which records the data on magnetic tape. Short summaries are also given of the following proposed research projects: 1) development and evaluation of remedial aids to warn drivers of slowly moving vehicles ahead on a grade; 2) evaluation of traffic controls for highway construction and maintenance operations on 2-lane highways; 3) measurement of vehicle equivalency and capacity including effects of commercial and recreational vehicles; 4) retention and presentation of highway traffic data collected on the Main Facility; 5) development and evaluation of dynamic aids for narrow bridges; 6) study of rest area usage; 7) development and evaluation of remedial aids for intersections with inadequate sight distance; 8) development and evaluation of transverse lines for traffic control and speed reduction; 9) study of effects of width of snowplowing on traffic operations; and 10) study of effects of adverse visibility and dynamic warnings of limited visibility.
