The data are illustrative. They are provided to show the option values associated with varying speeds and log-variability on a facility. In this table, the average speed, log average speed, and the standard deviation are calculated from observed speed data. The spreadsheet also contains plots of
This spreadsheet contains the data documented in the A3 Open-Ended Survey Results report, as listed in the Related Artifacts section.
After careful assessment of travel time reliability terms and the results obtained in the various human factors studies and experiments conducted throughout the course of the Project L14, the research team established three key hypotheses related to the use and value of travel time reliability in
The objectives of the first utility function laboratory study were (1) to assess the value participants placed on traveler information, and specifically reliability information, within the context of a simulated time-constrained trip, and (2) to determine whether having reliability information he
The experiment was conducted in five cities—Dallas, Denver, Hartford, Miami, and San Jose—over a period of 4 months and acquired information from 80 participants. Specific questions regarding levels of trip stress and on-time arrival confidence had to be completed at each waypoint and at the begi
SHRP2-L14's research team decided to use a multiple-choice survey to address comprehension and preference questions regarding reliability terms and associated trip information. The survey was conducted on laptops using the SuperLab software to present questions and instructions and to collect par
“D” Drivers is a term that has been coined for drivers who are drunk, drugged, drowsy, distracted, or just plain dangerous. These types of drivers are a hazard on the roadways and are one of the worst dangers to responders working an incident along a roadway. This video is meant to be delivered t
This video was created to demonstrate to responders the proper, safe way to deploy traffic cones when setting up a taper to further protect the incident scene. This video has been inserted into the training curriculum and is also constructed to be a standalone video for display to all responder d
This Data Flow Diagram explains the steps taken to extract the station metadata from PeMS and store the data in files. Description is also given of the process for filtering out stations which are out of order or fall outside the analysis time intervals.
Maps of the L33 analysis Sections (i.e. stretches of directional freeway to be analyzed, given a 4-digit id number). Compressed into a zip file. Some are in image files (.png), others are in Google Earth KML format.
This document explains the method used for calculating capacity.
This spreadsheet was used to calculate the capacities of sections analyzed in L33. For the calculation methodology, refer to the related artifact "Link Capacity Calculation".
This Data Flow Diagram shows the relationships between data and data processing programs related to Weather for the L33 project. Parallelograms represent data, and rectangles represent data processing programs.
This Data Flow Diagram shows the relationships between data and data processing programs related to Incidents for the L33 project. Parallelograms represent data, and rectangles represent data processing programs.

This document describes the process for creating the Google Earth KML files used to display the L33 analysis Sections (i.e. stretches of directional freeway analyzed).
This is one of three basic TTRMS analysis tools used by the Project L38B team. This corridor combining tool is used only if the corridor selected has more than one segment. Use this tool to combine the VMT and TT after running the VMT/TT database tool. Then imput the conbined TT/VMT int
