This model consists of three modules: vehicle specific power (VSP) distributions, energy consumption rates, travel time and mileages. The estimation results are validated and compared with those derived from driving cycles and instantaneous speeds. It is found that the VSP distributions can capture the variation of the energy consumption relating to average speeds, and the results are unbiased with average errors less than 1.9%, comparing with instantaneous speeds. It is practicable to employ the trajectories of ICEVs to model the activity of BEVs for energy consumption estimates, and the average errors are less than 2.7%.</div></div>","PeriodicalId":23277,"journal":{"name":"Transportation Research Part D-transport and Environment","volume":"137 ","pages":"Article 104509"},"PeriodicalIF":7.3,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142661938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through a natural driving experiment, we suggest traffic and road topology have a dominant role in influencing individual driving styles, more so than driver age or gender, or vehicle characteristics. Using experimental data and a Markov chain approach, we make three contributions to driving cycle development. First, we identify a reduced set of 26 metrics which materially influence fuel economy.

Many countries have legal retirement age limit for fleet vehicles (FVs), considered as policy constraint necessitating eventual replacement. Additionally, uncertainties like fuel price of ICEV and battery price affect the replacement decision. This study proposes an optimal replacement strategy using real option approach for annual decision-making under multiple risk factors. Using data from the Korean FV market, we provide managerial implications. Despite optimistic battery price projections, voluntary BEV switching is not expected to exceed 40% of total FVs. Sensitivity analysis reveals that adjusting the legal retirement age is more effective than changing the BGVSP implementation year.
