3 Lots of Data. Now what? Transportation agency emphasis on data collection, hardware/sensors, and building things Sensor Systems, Probe Data, Incidents, etc. University Data Snobs Ops Engineers, Planners, the media, public, and everybody else Database Significantly less emphasis has been given to: Ease of access Tools for exploring the data How to represent the data for differing users including Engineers, decision makers, the public H t t th dt f Visualization & Usability 3

6 Winter Weather Fun It s winter. Yesterday there was concern about icy roads in the morning. As a precautionary measure, the federal government (and most of the schools in the area) decided to open 2 hours late. Traffic seemed better than usual in the AM, and there weren t many accidents. Traffic even seemed better in the PM. Several politicians (and the media) are calling to ask for some stats on how the commute compared to normal. What are you going gto tell them? Date: January 23 rd, 2012 Road: I 66 Eastbound in Virginia

8 More Winter Weather Fun Snowmageddon There s been a request from the Governor s office to produce some examples that depict how bad trafficwas during the January 26 th, 2011 snow storm compared to normal weekday traffic. What could you produce for the Governor?

10 Statewide Reporting You ve been asked to provide a monthly statewide congestion report to the Secretary. This report only needs to cover the interstates, but it needs to highlight where the worst congestion occurred (top 10 locations) and some basic stats about the severity of the congestion at each of these locations. You also need to let the Secretary know if the congestion is about the same, better, or worse than theprevious 2 weeks. What do you do?

12 A bad day A high level manager in your department just arrived at work and complained about an accident that occurred along his commute this morning around 7:00 AM. The media and some public officials are calling the office, too, to try to get more information about what happened. This manager wants you to find out the details about this incident, but specifically, to figure out how long the bottleneck got, and how long the delays lasted. Any additional info you can glean would make his day (which isn t off to a good start.) The date is May 15 th, You work in Maryland This manager commutes on I 495, and he was heading on the outer loop (west bound) just north of DC D.C. when this occurred (at least, that s what he thinks you never can trust what this guy says )

14 I just spent $250M, and all got was this! Your DOT just spent $200M on a 6 month major road widening project along that corridor you (and everybody y else) hate. Some commuters are now complaining that things haven t improved in fact, they claim things have gotten worse. You can see the headlines now: $200M fattens road, shrinks commuter patience! What can you produce to show that the true impact of this recent investment.

15

16 Shorten my commute Your DOT is starting an innovative campaign to encourage commuters to be flexible in their working hours to shift demand on a heavily congested corridor in your region. As part of your campaign, you ve been asked to choose a small corridor and compare travel times during the AM commute each day to show how much of a shift in your commute start can impact your average travel time on that corridor.

17

18 The model modeler Your agency is trying to model a small 5 mile corridor in your state. As part of the modeling process, you ve been asked to provide some stats to the modelers. They need to know how speeds, planning time, travel times, etc. change during specific times of the day (like the morning rush hour and the evening rush hour.) They also want to know how these values change with the seasons (Summer vs. Winter). What info can you give them, and how might you get it?
