LIDAR has become one of the major enabling technologies for autonomous vehicles. LIDAR sensors generate 3D point cloud data around the instrumented vehicle. These data enable detailed localization of both fixed and moving objects in the surrounding environment. In this project, various aspects of LIDAR data processing are studied with an emphasis o

Connected vehicles (CVs) work by communicating with each other and the roadway infrastructure via dedicated shortrange communication. They are expected to eventually reduce non-impaired driver crashes by 80 percent, which will also significantly reduce traffic congestion. Researchers at Morgan State University in Baltimore, Maryland, spent 4 years

The objective of this study was to identify the risks associated with the failure of autonomous vehicles in mixed traffic streams and develop strategies to minimize these risks. Three distinct and interconnected phases were used to conduct the risk analysis; i) risk identification, ii) risk estimation and iii) evaluation. To identify the risks, the

Today, warehouses are transforming into massive “mega-distribution centers” located in increasingly suburban areas. However, the rapid delivery expectations of E-commerce will also perpetuate the need for a network of local, smaller-scale supply points. This document explores possible outcomes and transition considerations for warehouses.
Residential Preference: the social, environmental, and physical preferences that affect a person or family’s choice of residential location (for this report's purposes, in relation to the urban core and other amenities offered as a part of living in density). The introduction of autonomous vehicles and the comprehensive integration of E-commerce in

This study is the fourth in a series of four experiments exploring human factors issues associated with the introduction of cooperative adaptive cruise control (CACC). Specifically, the goals of this experiment were as follows:Assess drivers’ workloads under two different CACC following gaps (near and far).Assess drivers’ reactions to a vehicle mer

The study develops two different eco-routing systems and uses them to investigate and quantify the system-wide impacts of implementing an eco-routing system. The first one is basically a Nash Equilibrium feedback system, which uses the Ant Colony optimization approach; Ant Colony based ECO-routing technique (ACO-ECO). The comparison shows that the
