Connected Corridors

The Connected Corridors program is a collaborative effort among a range of stakeholders – including the California Department of Transportation – to research, develop, and test a framework for corridor traffic operations in California. Connected Corridors is investigating how corridor components (highways, arterials, buses, and rail) can work together efficiently so they can be managed as an integrated system, to reduce congestion and improve mobility. Connected Corridors will leverage new technologies: the internet, cellular and mobile devices, GPS technology, and social networking; along with building on the experience from previous PATH projects including Tools for Operational Planning (TOPL) and Mobile Millennium.

Mobile Millennium

Mobile Millennium is a traffic monitoring system which fuses streaming data from mobile and static sensors in real-time, to produce traffic estimates faster than the physics of traffic. It started as a smartphone based system, launched in 2008 jointly with Nokia. Today, it integrates dozens of data feeds totaling millions of data points every day feeding our system. It produces real-time estimates of traffic on all highways and major arterial roads in Northern California. A live visualizer is accessible to the public in the CITRIS museum at the CITRIS headquarters on the UC Berkeley campus.

Floating Sensor Network

The Floating Sensor Network is a water monitoring system which integrates mobile robotics platforms (motorized drifters) and live feeds of the Sacramento San-Joaquin Delta in California. The mobile floaters integrate a suite of sensors (GPS, salinity, temperature, etc.), and communicate to the ground through the GSM network and with ZigBee radios. They are deployed for finite duration missions and send data about the currents to a data assimilation system which integrates the streaming data into hydrodynamic models developed by LBNL, to produce real-time nowcast of the currents in the Delta.

iShake

Turn your iPhone into an earthquake-measuring device and get live maps of other users' shakes! UC Berkeley is conducting research on the validity of modern smart phones being used as mobile earthquake sensors. Contribute your phone as a sensor to the project. Simply turn the application on when you plug in your phone at night and any possible earthquake triggers measured by your phone will instantly be streamed back to our University servers for further processing and map generation.
