A report is given on the current status of land development adjacent to interchanges in Illinois. A comparison of land uses showed that 43 percent of rural facilities within 1/2 mile of the interchanges were completely undeveloped while only 2 percent of the suburban interchanges had no development around them. The fact that only 4 percent of the rural interchanges had substantial development in all 4 quadrants as compared to 30 percent of the suburban facilities is interpreted as an indication that it is 'not too late to initiate land-use planning and control.' A comparison of expressway interchanges with unnumbered routes vis-a-vis those with numbered routes (Federal and State designated highways) showed that the interchanges with unnumbered routes had more extensive land development than those with numbered routes. Approximately 75 percent of the suburban interchanges and 31 percent of rural interchanges evidenced existing or potential causes of congestion such as the existance of a major traffic generator nearby and insufficient cross-route capacity. The most prevalent congestion problem encountered was the location of ramp terminals in proximity to potential high-volume intersections.
