A method of obtaining a continuous reference signal for use in the synchronous longitudinal control of automated ground transport systems is presented and evaluated in preliminary fullscale tests. The results of the latter, which were obtained using a reference signal in conjunction with an instrumented vehicle at speeds from 0 to 46 ft/s over 1600 ft of roadway, are presented. Successful operation was achieved with both steady-state and time-varying velocity command signals. A significant finding, with resprect to implementation of the method, was that the roadway environment introduces signal attenuation (2 dB/100 ft) that must be circumvented before practical long-distance operation can be achieved. However, with system refinement, the technique holds great promise for future implementation.
