• Abstract:
  This report covers several key subjects related to the generation of IntelliDriveSM probe vehicle data and use of this data in ; application of interest to state departments of transportation and local public transportation agencies. The evaluations ; conducted as part of this project are primarily based on the probe vehicle data collection system that was deployed by the U.S. ; Department of Transportation (USDOT) around Novi, Michigan, in 2008 for its Vehicle‐Infrastructure Integration (VII) Proof‐of‐ ; Concept (POC) test program. This system was designed around the use of the 5.9‐GHz Dedicated Short Range Communication ; (DSRC) wireless protocol to enable vehicles to communicate with Roadside Equipment (RSE). The generation of snapshots ; further followed the protocols defined within the SAE J2735 DSRC Message Set standard. ; Following a general introduction in Chapter 1, Chapter 2 briefly reviews the protocols that were used to generate and retrieve ; probe vehicle snapshots, while Chapter 3 presents a general evaluation of the POC test data that were accumulated during the ; 2008 test program. This is followed by a presentation in Chapter 4 of the evaluation framework of the current project. This ; presentation includes an overview of the envisioned DUAP system and descriptions of project stakeholders, potential data ; sources, supporting technologies, applications of interests, and potential operational constraints. Chapter 5 then presents a ; general description of the Paramics IntelliDriveSM virtual simulator that is used to conduct some of the subsequent evaluations. ; While the initial POC test program aimed to evaluate data collection capabilities across a range of application, this program ; was significantly shortened due to various technical issues. This resulted in incomplete data collection and partial application ; designs that were insufficient to complete the initial project deliverables associated without rely on simulation. Chapter 6 ; then examines the effects of snapshot generation protocols and privacy policies on data latency, data quality, and the ability ; to track vehicles over short distances. Chapter 7 follows with a mapping of application data needs and general descriptions of ; processes required to convert raw probe data into useful information, while Chapter 8 evaluates how basic traffic flow ; performance measures (flow rates, flow density, travel times, speed profiles, queue parameters) can be estimated from probe ; data in systems featuring full and partial proportions of probe vehicles. Chapter 9 further develops a concept of operations for ; an enhanced traffic monitoring system incorporating probe vehicle and other data sources, while Chapter 10 investigates ; various issues that must be considered when developing application deployment plans. Chapters 11, 12 and 13 finally present ; a summary of primary findings, lessons learned and recommendations for future work.
