An Analysis of the Travel Conditions on the U.S. 52 Bypass in Lafayette, Indiana

چکیده
In recent years vehicular travel has increased at a tremendous rate. The construction of new highways and the improvement of existing facilities have failed to keep pace with the growth of motor-vehicle travel. The problem is especially acute in urban areas, where major arterial highways lack needed capacity for handling the large movements of intracity travel. Many urban roads were constructed decades ago, when the present status of vehicular travel was inconceivable. Inade quate planning and improvement of these facilities have resulted in congestion and delays which are costly and irritable to road users. Limited-access freeways are being constructed in large urban areas to accommodate the major flows of through and intracity travel. Existing arterial highways continue to play an important role in the movement of traffic, however, and they serve as collectors and distribu tors for the new expressways. Through sound traffic engineering techniques, the improvement of these arterial facilities is necessary for the efficient and safe functioning of the complete transportation system of an urban area. W ith a large expenditure of funds for the con struction of new roads, the continuing renovation of the present highways has been largely neglected. The purpose of this research investigation was a detailed analysis of travel speeds and delays on a congested arterial highway located in an urban area. (5 )* The facility selected for study was the U. S. 52 Bypass in Lafayette, Indiana. The specific objectives of this traffic engineering evaluation were the following:
