      <title>A novel coaxial multi-mode hybrid transmission system for mining trucks</title>
      <link>https://trid.trb.org/View/1648759</link>
      <description><![CDATA[Given that hybrid electric vehicles could significantly reduce fuel consumption, and mining trucks are much more sensitive to energy conversion efficiency, it is essential to develop a hybrid system, which could meet both the specific requirements of the structure of mining trucks and the needs for overall efficiency improvements. In this paper, a novel multi-mode transmission system, which is composed of an engine, two motors, one planetary gear set, and a parallel transmission structure, is proposed. The planetary gear set serves as a power-split device, and the parallel transmission structure can make the engine and motor work in the high-efficiency area both in low-speed and high-speed conditions. Due to the flexibility of the proposed system, five power-flow modes can be implemented, and they are illustrated with a specially designed rule-based energy management strategy. To validate the effectiveness of the multi-mode transmission system, dynamic programming is used to assess the fuel consumption during the given driving cycle without considering drivability. The simulation results reveal that the proposed multi-mode transmission system owns better fuel efficiency for mining trucks compared with highly regarded Toyota Hybrid System and conventional automated manual transmission system.]]></description>

      <title>The Relation Between Technological and Market Development: Its Effects on Fuel Efficiency in the Swedish New Car Fleet</title>
      <link>https://trid.trb.org/View/886658</link>
      <description><![CDATA[This paper analyzes technological development for new passenger cars in Sweden between 1975 and 2002. The aim is to estimate the fraction of technological development that has been directed to or resulted in reduced fuel use. The paper concludes that approximately one third of the technological development since 1985 has resulted in a reduction of fuel consumption while the remaining 2/3 have enabled a wide spread use of larger and more powerful cars.]]></description>

      <title>A STREAMLINED METHODOLOGY FOR APPLICATION OF TRANSYT-7F</title>
      <link>https://trid.trb.org/View/481136</link>
      <description><![CDATA[Between 1985 and 1993, technical support for all southern California participants of the State's Fuel Efficiency Traffic Signal Management (FETSIM) program was provided using the signal timing tool, TRANSYT-7F.  Throughout the technical support phase, refinements were made to the original TRANSYT-7F program in order to give traffic engineers greater flexibility in achieving their particular signal timing goals. The data collection requirements found to be of most value were traffic volumes, stopline lane configuration, and intersection-to-intersection distances and free speeds.  The methodology was effectively used and produced significant reductions in traffic signal delays, stops and an increase in speed.]]></description>

      <title>EVALUATION OF THE FUEL-EFFICIENT TRAFFIC SIGNAL MANAGEMENT (FETSIM) PROGRAM: 1983-1993. FINAL REPORT</title>
      <link>https://trid.trb.org/View/451632</link>
      <description><![CDATA[This report presents the findings from the evaluation of a statewide initiative to retime traffic signals to produce more energy-efficient traffic flow:  California's Fuel-Efficient Traffic Signal Management (FETSIM) Program.  During the 11 years of the Program, over 160 cities and counties have retimed a total of 12,245 signals under grants from the FETSIM Program, in 334 projects.  Improved timings have reduced vehicular delays by 14% in project areas; stops have been decreased by 13%.  Overall travel times through these systems have dropped by 7% and fuel consumption has been cut by 8%.  The reduction in fuel expenditures alone has produced annual savings of $85.1 million for California motorists--more than 5 times the total cost of the FETSIM Program.  Reduced vehicular wear and tear and faster travel times added as much as $189.3 million annually in user benefits.  Other benefits include reduction of air pollution emissions, traffic safety improvements, and better operating conditions for public transit vehicles.  The Program also strengthened the capabilities of local traffic engineering staff, and has built better data bases for future traffic studies in participating communities.  The FETSIM Program was carefully designed to offer local agencies the tools, know-how and financial assistance necessary for improving the timing of traffic signal systems.  Grants have been awarded for all aspects of retiming, including the costs of data collection, development of timing plans, implementation and field evaluation.  Training and technical assistance in advanced methods for achieving optimal signal timing has been provided to the staff and consultants of the participating agencies.  A number of research and development activities in support of the Program have produced improved analysis tools for traffic signal management that are used by practicing engineers nationwide. The FETSIM Program has served as a model for several statewide signal management programs across the country.  It has received recognition as a major success, not only in California but nationally.  In 1985, the California Energy Commission and the California Department of Transportation received the Institute of Transportation Engineers' Transportation Energy Conservation Award for the Program.]]></description>
