Travel time reliability reflects the distribution of travel time of trips using a facility over an extended period of time. This distribution arises from the interaction of a number of factors that influence travel times:

This final report documents the activities performed during SHRP 2 Reliability Project L08: Incorporating Travel Time Reliability into the Highway Capacity Manual. It serves as a supplement to the proposed chapters for incorporating travel time reliability into the Highway Capacity Manual prepare

SHRP2 Project L08 is developing methods and guidance on incorporating travel time reliability into Highway Capacity Manual (HCM) analyses. The main product of this project will be a guidebook that describes travel time reliability concepts for an HCM audience, provides step-by-step processes for

This Amplified Work Plan provides an overview of the approach to the research and documentation to fulfill the specifications for the SHRP2 L10: "Feasibility of Using In_Vehicle Video Data to Explore How to Modify Driver Behavior that Causes Non-Recurring Congestion."

This is a summary of findings from Project L10: "Feasibility of Using In-Vehicle Video Data to Explore How to Modify Driver Behavior that Causes Non-Recurring Congestion."

Nonrecurring congestion is traffic congestion due to nonrecurring causes, such as crashes, disabled vehicles, work zones, adverse weather events, and planned special events. According to data from the Federal Highway Administration (FHWA), approximately half of all congestion is caused by tempora

This one page document, "Planning Cost-Effective Actions to Improve Travel-Time Reliability", briefly summarizes the requirements, actions, and performance-based planning options to improve non-recurring congestion.

Poster explaining graphically and concisely the project.

This project brief, titled "Travel Time Reliability 2030: Innovations and Strategies for Today and Tomorrow" provides an overview of two SHRP2 reliability projects: Project L11 (Evaluating Alternative Operations Strategies to Improve Travel Time Reliability) and Project L15B (Proximity Informatio

This project recognizes the imperative to maximize the value and capabilities of our existing transportation infrastructure, and to do so in the context of a collaborative decision-making process that allows agencies and jurisdictions to make prudent decisions for investing scarce resources.
