Contains all PDCMs generated during the AMCD field testing program. The PDCM is a control message sent from the server to OBUs to customize a request for Probe Vehicle Data (PVD) from the receiving OBU. All PDCMs are generated by the VCC Cloud server and transmitted to OBU clients through either a DSRC or cellular communications channel.

The data in this data environment was collected from the Pasadena, California testbed, namely I-210, SR 134, and nearby arterials. The source of these data is from the Caltrans – Performance Measurement System (PeMS). Speed data from this dataset were used to derive the freeway travel time. There are three separate text files with one for each operational condition.

Data is from the small-scale demonstration of the Intelligent Network Flow Optimization (INFLO) Prototype System and applications in Seattle, Washington. Connected vehicle systems were deployed in 21 vehicles in a scripted driving scenario circuiting this I-5 corridor northbound and southbound during morning rush hour. This data set contains queue warning messages that were recommended by the INFLO Q-WARN algorithm and sent by the traffic management center to vehicles to warn drivers upstream of the queue. The objective of queue warning is to provide a vehicle operator sufficient warning of impending queue backup in order to brake safely, change lanes, or modify route such that secondary collisions can be minimized or even eliminated.

Data is from the small-scale demonstration of the Intelligent Network Flow Optimization (INFLO) Prototype System and applications in Seattle, Washington. Connected vehicle systems were deployed in 21 vehicles in a scripted driving scenario circuiting this I-5 corridor northbound and southbound during morning rush hour. Basic Safety Messages (BSM) sent by connected vehicles (CVs) through either the cellular network or Dedicated Short Range Communication (DSRC) when the vehicle is in the range of Roadside Units (RSU). These messages were received by the traffic management center (TMC).

Contains all PVDs generated during the AMCD field testing program. The probe vehicle message is used to exchange status about a vehicle with other DSRC readers to allow the collection of information about a typical vehicle’s traveling behaviors along a segment of road. The exchanges of this message as well as the event which caused the collection of various elements defined in the messages are in Annex B of the SAE J2735 standard.

This report contains tables and charts on the financial condition of the U.S. major airlines. All data presented in this financial and traffic review are derived from data reported to the U.S. Department of Transportation on Form 41 Schedules by Large Certificated Air Carriers. The data are presented on both a carrier group and an individual carrier basis, but the primary focus is on the individual major carrier and its performance. Data are presented for the most recent quarterly period and the comparable quarter a year earlier and also on a 12-month ended basis as at the end of the five most recent quarters. In addition, data on changes over comparable periods 12-months earlier are presented. A graphic presentation of comparative trends, on a carrier group basis, is made for several unit and overall financial indicators. In the case of merged carriers, data for the carriers involved have been combined and presented under the name of the surviving carrier so that meaningful comparisons could be made. Carrier Group Definitions Majors: Air carriers with annual operating revenues exceeding $1,000,000,000 https://www.transportation.gov/policy/aviation-policy/airline-quarterly-financial-review
