The construction of a grade separated High Speed Ground Transportation System (HSGT) employing tracked air cushion vehicles (TACV) and linear induction motors (LIM) is physically feasible between LAX and a site near the Van Norman Lakes in the San Fernando Valley, via alignment mostly within the right-of-way of the San Diego Freeway. Speed restrictions are imposed on the HSGT limiting operations to less than 150 mph through much of its route. A primary objective in the steady of the freeway alignment was to develop a route permitting a design speed of 150 mph. This speed was able to be attained in two sections of the preferred alignment described herein. It was determined that planning should proceed on the basis of double U-shaped guideways of given dimensions. Tradeoffs between span length and number of foundations resulted in a tentative guideway span of approximately 100 feet. A satisfactory structural system has been developed employing mostly cast-in-drilled-hole piles, concrete pile caps or concrete spread footings, concrete T-columns and concrete guideways spanning between the T-columns. T-columns are replaced by straddle bents where required over freeways or over freeways ramps. Three passengers stations are proposed for initial construction of the 16.4-mile route. 1,500 volt direct-current electrification system was selected for costing purposes. Power was proposed to be distributed to the vehicles through composite aluminum and steel contact rails. Travel time over the 16.4-mile route from the LAX Station to the San Fernando-South Station would be about 11 minutes with an average speed of approximately 89 mph. Speeds between the top speed of 150 mph and 100 mph would be achieved for a distance of approximately 46,000 feet. The effect of the proposed HSGT on freeway traffic would be minimal and no foreseeable serious safety problems would be created by the HSGT.
