From Information to Action

• How do we get here?

• The PeMS is Here!

Data Collection Devices

In Roadway Inductive Loops Magnetometers (Sensys) Weigh-in-Motion (WIM)

In Right-of-Way Radar (Laser, Infrared, Microwave) Doppler, Ultrasonic, Side-Fire Toll Tag Video

Virtual GPS - As Probe Vehicles Bluetooth and Media Access Control (MAC) Readers Third-Party Data Transit Providers

Hybridize - E pluribus unum

We Still Need the Same Information Such as Volumes, Speeds, Travel Times and Delay

We Need to Continue to Ensure the Validity of the Date we are Using

We Also Need to Determine Its Value for Different Purposes 511 Traveler Information Transportation System Planning Transportation Network Management

Corridor Management

Prop 1B of 2006 – provided nearly 4.5 billion for delay reducing projects.

CSMP – Corridor System Management Plans used to outline the multi-jurisdictional and

multi-modal management of a corridor experiencing delay due to congestion.

results in a listing and phasing plan of recommended operational improvements, Intelligent Transportation System (ITS) strategies, and system expansion projects to preserve or improve performance measures within the corridor.
