Summary: Shaun will present on the recently completed pilot demonstration of multimodal arterial performance measures for the Portland metro region, as part of the larger regional concept of operations. Treatments include a permanent bike count station on the Springwater Trail, permanent truck classification stations, Bluetooth travel time stations, as well as leveraging existing transit and signal controller data to paint a picture of the collective modal transportation system.

Bio: Shaun Quayle is a transportation engineer with Kittelson and Associates, Inc. (www.kittelson.com). His focus areas of practice are in the operations, planning and design of arterial traffic signal systems, performance management systems, and complex traffic analysis and simulation.

The ability to forecast future transportation patterns under a particular land-use scenario or urban form is key to making informed decisions at the local and regional levels.

Although several researchers have explored the links between the built environment, socio-demographics and travel behavior, a consensus is not reached.

This talk highlights two recent projects. The first project focuses on individuals’ attitudes towards transportation, neighborhood characteristics and their effects on campus commuters’ transit use, and addresses the question whether attitudes, the built environment or a combination of both explains the resulting transit use better.

The second part presents the Regional Land Use Allocation Decision Analysis Tool developed for The Ohio Department of Transportation, which enables decision makers to quantify the impacts of population and employment distribution in terms of the resulting VMT (Vehicle Miles Traveled). This tool forecasts the impacts of future land-use policies in Ohio, based on alternative assumptions of highway and mass transit corridor development, zoning and environmental constraints, regional growth or decline...

Summary: The recent City Club report on bicycling provided an opportunity to collect and analyze a number of data sets including the new Hawthorne Bridge data. One question is where Portland bicycling on the logistic curve -- a common tool for judging the maturity of a developing product or activity. Logistic curves are used for marketing, for epidemiology, and even for visits to Indian owned casinos. The preliminary evidence is that we are reaching the horizontal area of the curve. Additional evidence Our further research into future policies indicates a shift to bicycle boulevards in order to attract more risk averse riders.

OVERVIEW

This webinar will demonstrate the tremendous value of GPS trajectory data in understanding statewide travel patterns and measuring performance. First, Dr. Markovic (U of Utah) will conduct visual exploration of GPS trajectories that capture about 3% of all the trips in Utah. He will briefly discuss the problem of scaling GPS trajectories to the population, and then focus on the use of scaled trajectories in computing origin-destination matrices, vehicle-hours delays, vehicle-miles traveled, and trip-based performance measures. Second, Dr. Franz (CATT Lab) will demonstrate a suite of visual analytics that enables transportation agencies to easily explore terabytes of GPS trajectory data. He will demonstrate different tools and share the experience of 5 state DOTs that are currently using CATT Lab's trajectory data suite.

KEY LEARNING OUTCOMES

• Trajectory data represents the most complete vehicle-probe data and provides unprecedented opportunity for transportation system analysis.
• Transportation agencies can easily leverage visual analytics to obtain insights in statewide traffic patterns and...
