Signing for traffic generators is considered supplemental to the overall signing as provided Section 2E -28 of the Manual on Uniform Traffic Control Devices."Guideline Criteria for Signing Traffic Generators" (Table II) have been established so that facilities which generate the greatest need for information by motorists will receive priority in the use of supplemental guide signs.
Other generators that may qualify for signing on the conventional highway system are not normally of interest to the freeway or expressway user or critical to navigational guidance for a significant proportion of freeway or expressway users. Table 1 is not all-inclusive, but provides an indication of the type of facilities not warranting signs.
