4

Why?

From the Bureau of Transportation Statistics, National Transportation Statistics 2009

6.3%

53.2%

95.7%

5

Countermeasures

Construct new roads

Reduce traffic

Increase capacity of the existing infrastructure by employing ITS technologies

Travel demand control

Improve transit service

6

Is It a Possible Approach?

Do you think we can increase highway capacity by applying advanced technologies?

Details?

CEE 579 Advanced Traffic Detection Systems 3 credits. Spring Quarter

General introduction to the following systems:

Radar gun Remote Traffic Microwave Sensor (RTMS) GPS based vehicle navigation Priority Vehicle Detection Weigh In Motion (WIM) sensors

In depth instruction on Inductive loop detection systems Computer vision based detection systems

10

Nationwide Network of Data

To a nationwide network of data

From Spots of data

A Public Private Partnership: shared risk shared benefit shared contribution

11

How To Handle These Data?

If loop measurements are archived every 20 second, 4,000 single loop detectors require

24 * 3600 / 20 * 50 * 4000 = 864 MB storage space per day!

Remember this is just data from loop detectors. We have also accident data, freight data, video data, …, to deal with!

With these data in hand, how to manage and use them sufficiently to support our decision making?

12

That’s Why We Offer CEE 412

CEE 412: Transportation Data Management and Analysis

• Store and retrieve transportation data efficiently become increasingly important• Optimal decisions should be made based on computation results from these available data

This course will help to build up fundamental knowledge and skills for database design, data management, and basic skills for transportation analysis.

13

Intelligence Requires Data

With good traffic data, we can make our control systems smarter than this .
