This project initiates a general framework for assessing population-specific impacts of Caltrans projects on avian populations with the future goal of providing specific tools to avoid impacts with hummingbirds nesting on or around bridges.
Researchers propose a hierarchical ramp control system that allows microscopic cooperative maneuvers for connected and automated electric vehicles (CAEVs) on the ramp to merge into mainline traffic flow under certain controlled ramp inflow rate.
This dataset is from research that applies a life cycle perspective to assess the energy use, greenhouse gas emissions, air quality impacts, and costs of on-road freight vehicle technologies and operational strategies identified under the Sustainable Freight Action Plan.
These data stem from a project that developed a powerful and user-friendly web-based version of the Integrated Transport and Health Impact Model tool for the Sacramento Area Council of Governments (SACOG) six county region
A second-by-second data set obtained from monitoring vehicle emissions over a series of 75 test runs from 2 test vehicles over an 18-month period during real-world on-road operations was used to assess emissions differences between two propulsion systems and attribute these differences to physical roadway/infrastructure characteristics.
