New tool simulates real-world vehicle traffic to predict large-scale energy impact

From a metropolis’s rush-hour commute to the operations of a cross-country transport fleet, a brand new software from the U.S. Division of Power’s Argonne Nationwide Laboratory can paint an image of how autos are utilizing power on a big scale.

The software, known as Autonomie Categorical, is designed to assist transport and mobility corporations, researchers, city planners and others estimate their autos’ power consumption and greenhouse gasoline emissions. The software—free to all customers—assesses power consumption for a variety of autos, each present and future.

“You can ask, what if 50% of these vehicles were battery electric—what impact would that have on traffic flow?” says Phillip Sharer, supervisor of Argonne’s model-based programs engineering group. “Over the last 20 years, transportation has become more complex with the onset of new technologies, both at the powertrain level and the vehicle level, as well as the intelligence that’s being added to vehicles and roadways. We have a mix of conventional vehicles, hybrid autos and electric vehicles of various sizes on the street immediately, and we anticipate extra within the years to return.”

To account for this new complexity, Autonomie Categorical is provided with an unlimited library of car sorts, from light-duty passenger automobiles to heavy-duty vehicles. It fashions their particular person powertrains, gasoline financial system and battery utilization.

Autonomie Categorical even consists of fashions that are not but obtainable to the general public. With the assistance of producer specs, its library consists of new autos projected by way of the 12 months 2050.

“The vehicle simulations in Autonomie Express encompass all modern vehicles that are currently on the road, as well as those that are expected to be on the road in the next two decades,” stated Ram Vijayagopal, supervisor of the car and know-how evaluation group. “By being able to select from more than 5,000 full vehicle models, transportation engineers can develop realistic simulations of present and future fleets.”

Autonomie Categorical could make it simpler for stakeholders to see the impression of their present practices and car fleets, in addition to present how they’re enhancing. For instance, it may well estimate how a lot a transport firm can save by switching to electrical autos, or how a lot rush-hour site visitors contributes to a metropolis’s power consumption.

The software is designed to work along side small- and large-scale traffic flow simulation instruments similar to Aimsun, PTV Vissim, Eclipse SUMO, or Argonne’s POLARIS to mannequin the impression of latest applied sciences similar to electrification, connectivity and automation when deployed at scale.

The Autonomie Categorical growth workforce is led by Aymeric Rousseau, director of the car and mobility programs division.

“Express has been designed to be easy to use,” Rousseau stated. “Vehicle selection and connection with micro- and meso-simulation tools has been streamlined through a graphical user interface. Pre-defined fleets for multiple scenarios provide ready-to-go solutions for researchers to accurately estimate energy impacts of technologies.”

The workforce lately introduced Autonomie Categorical’s availability, freed from value with a license. They hope it’s going to incentivize customers to embrace extra energy-efficient, environmentally accountable transportation choices by displaying them the place to start out.
