COMPARATIVE ANALYSES FOR DESIGN MODIFICATION OF A DIAMOND INTERCHANGE

This is a summary of the analyses and recommendations for design modifications proposed for the existing State Route 60/Frederick Street interchange in Moreno Valley, Riverside, California. Development improvement options are reviewed, and the traffic operations are described as well as design criteria. It is noted that the effectiveness of many rural diamond interchanges constructed in the 1960s have been seriously diminished by the increases in traffic demand. Many of these interchanges, because of restrictive geometry and right-of-way, do not provide room for expansion and modification. Such modifications require careful consideration of their impact on traffic operation. Options must be carefully analyzed for traffic operation. The addition of a direct on-ramp in the northwest quadrant and in the southwest quadrant, combined with relocating the existing on- and off-ramps to the adjacent local street and signalization and signal progression, yields an optimal solution.
