3. PacTrans STAR Lab Research on DRIVE Net Background 2 Picture source: http://en.wikipedia.org/wiki/I-35W_Mississippi_River_bridge How to monitor health condition of transportation infrastructure? Which infrastructure piece is the most critical for the roadway network?

4. PacTrans STAR Lab Research on DRIVE Net Other Sample Key Questions How to quantify the benefit from a transportation investment? How to measure vehicle miles of travel/vehicle hours of travel? What is the impact of a road construction project on travel? How to estimate traffic emissions at a given location and time? What is the impact of toll on users of different income levels? Where do pedestrians go and how to improve their safety? Which route deserves top priority to build? How to improve transit services without adding new resources? How does congestion form up and how to mitigate it? How much does an incident cost and how to reduce the cost? Where do trucks go and how to guide them to the best routes? 3
