A major update included in the HCM2010 is the inclusion of more multimodal methods and applications. None is more groundbreaking than the new Urban Streets methodology that includes new multimodal level-of-service methods for autos, pedestrians, bicyclists and transit riders. Learn about the new state-of-the-practice for multimodal analysis as it relates to bicycle, pedestrian and transit users.

At the conclusion of the course, participants should be able to:

1) Discuss the impacts of various inputs on the LOS of each mode.
2) Discuss recent case studies of how the methodology has been applied.
3) Work through an example problem using analysis software.

With the powerful HCM2010 Freeway Facilities methodology, an analyst is able to evaluate several miles of an extended freeway facility over up to six hours of varying traffic demands. The method integrates HCM methods for freeway component segments (basic freeway segments, merge and diverge segments and freeway weaving segments), and estimates their individual and aggregated performance in both under-saturated and oversaturated conditions. The methodology is implemented in the FREEVAL computational engine, which is available to users on the HCM2010 Volume 4 website. The focus of this webinar is on applications of the freeway facility method to real-world applications, including recurring bottlenecks, work zone impacts, and even weather effects on freeway performance. The talk will further discuss ways to adapt the existing HCM method to allow the evaluation of Active Traffic and Demand Managements (ATDM) strategies, including ramp metering, hard-shoulder running, freeway service patrols, and demand management impacts of route diversion or peak spreading. The webinar will conclude with a discussion of calibration and validation approaches that can be applied to relatively quickly adapt the method to match field-observed performance.

At the conclusion of the course, participants should be able to:

1) Discuss the capabilities of the Freeway Facility method.
2) Apply the FREEVAL computational engine to evaluate freeway facilities.
3) Use the method to evaluate effects of freeway work zones, incidents, weather, and ATDM strategies.
4) Describe how the method can be calibrated to match field-observed performance.
