This report describes the results of an effort to implement and analyze the performance a vehicle control system using control state information obtained from a carrier phase Differential Global Positioning System (DGPS) aided Inertial Navigation System (INS). Keywords: Vehicle Positioning...

This project is concerned with accurately and reliably determining the state of a vehicle relative to a specified trajectory (e.g., a lane centerline). We are utilizing inertial navigation methods based on inexpensive solid state inertial sensors aided by external sensors such as carrier phase...

Intelligent Transportation Systems (ITS) have generated considerable enthusiasm in the transportation community as a potential means to improve roadway safety, reduce congestion, enhance the mobility of people and goods, and reduce energy consumption and vehicle emissions. In order to estimate...

This report describes preliminary research dealing with vehicle emissions associated directly with Automated Highway Systems (AHS) and ramp metering. In performing this analysis, a power-demand model emissions model was integrated with several transportation simulation models in order to...

Through measures like Senate Bill 375, California has emerged as a national leader in the fight to lower CO2 emissions. To achieve CO2 targets, more attention needs to be paid to ITS. More before-and-after evaluation of ITS projects under a wider range of conditions is also needed to better...

Among several strategies to reduce greenhouse gas emissions from motor vehicles, “eco-driving†is one that had not received much attention in the United States (U.S.) until recently. The core of eco-driving programs is to provide drivers with a variety of advice and feedback to...
