Assessing and Mitigating Future Impacts to the Federal Highway Trust Fund Such as Alternative Fuel Consumption NCHRP Project 19-05 CHAPTER 4 CONCLUSIONS AND SUGGESTED RESEARCH This research has shown that while there are serious threats to the continued usefulness and stability of motor fuel taxes, those threats are not unlimited, nor are they likely to have major impacts over the reauthorization period. There are, however, several potential factors of concern to transportation agencies. Read the entire page →
