An optimization model of energy and transportation systems: Assessing the high-speed rail impacts in the United States

摘要: Abstract This paper presents a long-term investment planning model that co-optimizes infrastructure investments and operations across transportation electric systems for meeting the energy needs in United States. The developed passenger is integrated within modeling framework of National Long-term Energy Transportation Planning (NETPLAN) software, applied to investigate impact high-speed rail (HSR) on interstate portfolio, fuel electricity consumption, 40-year cost carbon dioxide (CO2) emissions. results show there are feasible scenarios under which significant HSR penetration can be achieved, leading reasonable decrease national CO2 emissions costs. At higher approximately 30% relative no portfolio promises savings up $0.63 T, gasoline jet consumption reduction 34% trips, by about 0.8 billion short tons, increased resilience against petroleum price shocks. Additionally, sensitivity studies with respect light-duty vehicle mode share reveal order realize such emission benefits, change choice essential ensure ridership HSR.
