Due to increased public awareness on global climate change and other energy environmental problems, a variety of strategies are being developed used reduce the consumption impact roadway travel. In advanced traveler information systems, recent efforts have been made in developing new navigation concept called "eco-routing," which finds route that requires least amount fuel and/or produces emissions. This paper presents an eco-routing system determines most eco-friendly between trip origin...
<div class="section abstract"><div class="htmlview paragraph">Marine ports are an important source of emissions in many urban areas, and implementing plans to reduce greenhouse gases using zero-emission cargo handling equipment. This paper evaluates the performance activity profiles for various (ZE) transport equipment being demonstrated at different California. included 23 battery-electric (BE) 8,000 lb.

The objective of this research was to collect real-world activity data from agricultural equipment that could be considered when informing air quality and incentive programs in California. This included monitoring 208 tractors via either engine hour records or loggers, with 103 these monitored loggers. results showed the average annual hours usage for agriculture declined as a function age/older technology. were 60, 130, 143, 741, 739 h, respectively, Tier 0, 1, 2, 3, 4 tractors. used about...
In recent years, the development of connected and automated vehicle (CAV) technology has inspired numerous advanced applications targeted at improving existing transportation systems. As one widely studied CAV technology, eco-driving takes advantage Signal Phase Timing (SPaT) information from traffic signals to enable CAVs approach depart signalized intersections in an energy-efficient manner. However, majority studies have been numerical or microscopic simulations. Only few implemented...
Even though heavy-duty battery electric trucks (BETs) have become commercially available, their range limitation still hinders widespread adoption.Drayage has been regarded as a suitable application for early BETs due to typically having limited daily mileage.However, drayage operation can vary widely and some form of extension may be needed operating in this application.In paper, wireless charging at port terminals is proposed purpose.Potential zones are identified, efficacy extend BET...
Heavy-duty trucks are a major source of transportation-related greenhouse gas and criteria pollutant emissions. One approach to reducing the climate health impacts these is transition them zero-emission technologies such as battery electric (BETs). To date, BETs have been deployed mostly in drayage application. As performance has improved recent years, there increasing interest using also regional haul This paper examines real-world activity patterns 15 heavy-duty application data collected...
Class-8 battery electric trucks (BET) are modeled and simulated in this paper to determine their capability fulfilling real-world drayage activity under different operational scenarios. Potential wireless charging zones at port terminals identified, opportunities introduced improve fulfillment of BETs. The results show that current BETs would be able fulfill approximately 79-86% the sample used research, ability receive opportunity could help increase about 84-91%.
Real-world vehicle and engine activity data were collected from 90 heavy-duty vehicles in California, United States, most of which have model year 2010 or newer are equipped with selective catalytic reduction (SCR). The represent 19 different groups defined by a combination vocational use geographic region. using advanced loggers that recorded speed, position (latitude longitude), more than 170 aftertreatment parameters (including load exhaust temperature) at the frequency one Hz. This...
Intelligent Transportation System (ITS) technology is often aimed at improving vehicle safety and mobility. Lately a number of ITS applications are also focusing on environmental issues such as reducing greenhouse gases (through improved fuel economy) overall pollutant emissions. Typical (e.g., eco-routing) focus total mass emissions for generalized areas. To date however, haven't considered from exposure point-of-view. In this paper, we introduce new routing methodology that goes beyond...

Surface transportation accounts for a large fraction of greenhouse gas emissions around the world. Vehicles powered by internal combustion engines are becoming increasingly fuel efficient and produce less through number technological improvements. One technology category is providing real-time "eco-driving" feedback to drivers, so that they drive more efficiently. Since hard accelerations have major effect on vehicle consumption emissions, some eco-driving systems been developed provide...

Author(s): Raju, Arun; Vu, Alexander | Abstract: Significant electrification of the transportation sector is necessary for State to achieve several important greenhouse gas (GHG) reduction and renewable energy targets. The State’s electricity generation transmission capabilities must increase in order meet demand generated by increasing levels fleet electrification. increased demand, combined with Renewables Portfolio Standard (RPS) targets will require significantly storage that can...
Author(s): Raju, Arun S.K.; Vu, Alexander | Abstract: California has set aggressive vehicle electrification goals to achieve its greenhouse gas (GHG) reduction targets. The state is also integrating renewable energy into the electric grid under Renewables Portfolio Standard (RPS). Increasing electricity demand from vehicles, combined with increasing power generation variable sources like solar and wind, will require significantly increased electrical storage capabilities, such as batteries...
