DEVELOPING PASSENGER-CAR EQUIVALENTS FOR LEFT-TURNING TRUCKS AT COMPRESSED DIAMOND INTERCHANGES

A study on the effects of light and heavy trucks on left-turning queues at compressed diamond interchanges is described. The headway method was used for determining passenger-car equivalents (PCEs) of various left-turning light and heavy truck classes, including some specialty vehicles. Inside turn radii were 15 to 18 m (50 to 60 ft), which is typical of many left turns for compressed diamond interchanges, where freeway on/off ramps are brought in as close to the freeway as possible. Composite PCEs for standard light and heavy trucks are reported as 1.7 and 4.4, respectively. PCEs for specialty vehicles are given as well.
