Though federal law does not mandate signage programs in the states the Federal Highway Administration does set standards for logo signs and TODS on federal routes. In some cases, additional directional signs are located on exit ramps and along feeder routes. See photo TODs, on the other hand, are located only on non-interstate highways. TODS provide motorists with the name of local tourist attractions, mileage to the establishment, and directional arrows. Billboards, on the other hand, are a far more expensive advertising medium.
Logo signs are very effective in directing travelers to roadside businesses.
Though a relatively new program, TODS have already proven a real benefit to local businesses. In Michigan there are specific criteria each type of business must meet to be eligible for the TODS or Logo sign program. An attractive community generates business and attracts homeoweners. An attractive community is also a healthy community. It instills a sense of pride, a sense of caring, and a sense of place.
