Research Overview

My research interests are in the areas of Transportation Cyber-Physical Systems (TCPS), also known as Intelligent Transportation Systems. My research focuses on two thrusts: First, the design and evaluation of new applications that are made possible by the communication and data collection technologies in TCPS. In particular, communication allows vehicles and infrastructures to collaborate, and “Big Data” makes it possible to predict the system status. Subsequently, we could improve the control and traffic management actions, as well as provide on-road infotainment; Second, the design and development of an integrated traffic-driving-networking simulator. Such an integrated simulator is not only useful for evaluating the proposed TCPS applications that require simulation models from multiple disciplines, but also is an essential tool for evaluating and experimenting with the designs of various Connected Vehicle and Autonomous Vehicle technologies.

Selected Funded Projects

Smart Campus Parking

The objectives of transportation in a smart campus are to ensure safety, increase efficiency, and promote sustainability. Our current project focuses on improving parking by implementing a parking monitoring system that utilizes computer vision and IoT technologies to provide real-time information on available parking spots. A pilot of this system has been successfully launched at the Parking Structure East at CSUSB. For more information, please visit https://csusb-parking.appspot.com/


Cooperative Vehicle and Intersection Control

This video explains our vision for future traffic intersections.

Recent advances in TCPS will create a widely connected network that can be accessed by vehicles, transportation infrastructure, handhold smart devices, among others. This in turn will allow for control actions to be exerted on both the infrastructure and the vehicle sides. Our research focuses on the potential for Cooperative Vehicle and Intersection Control (CVIC) to improve sustainability in transportation systems. Our proposal involves joint decision-making for traffic light timing and vehicle speed control, with the aim of reducing energy consumption.

(The video above, however, is not really about CVIC intersection but a precise choreography and mostly post-production trickery, credits to Black Sheep Productions).

Intersection Management and Cybersecurity

Traffic Management Systems are becoming more vulnerable and susceptible hacking targets as they rapidly develop to become more connected and intelligent. The following video showcases what was "envisioned" in the 2003 movie, The Italian Job.

With the support of the Western Riverside Council of Governments (WRCOG), we investigated the possible cyber threats to the transportation system in the Inland Empire and  identified steps to address any shortcomings.


Integrated Simulation for TCPS

Transportation Cyber-Physical Systems requires simulation-based testing and evaluation due to the prohibitive cost of building realistic test beds. Our team has developed the Integrated Traffic-Driving-Network Simulator (ITDNS), available at http://www.cse.buffalo.edu/CTS/, which comprises of three components: a commercial traffic simulator (PARAMICS), a driving simulator with a car mounted on a six degree-of-freedom motion platform, and a widely used network simulator (ns-2). 

This ITDNS was awarded for its innovation at the ICCVE 2012 conference, and a demo of our prototype can be viewed in the short video.
