TripChain: A Peer-to-Peer Trip Generation Database


Published on

This is the presentation given by Jon Kostyniuk at the #ITEToronto2017 conference on August 1, 2017.

The TripChain framework represents an innovation in how trip generation data points can be stored and propagated for use within the transportation industry. This is accomplished through the implementation of a distributed, open peer-to-peer database for transportation professionals.

  3. 3. @TripChain Presentation Outline • Current State of Trip Generation • Summary of Survey Results • What is TripChain? • How does TripChain work? • Project Status and Next Steps • Questions 3
  4. 4. Current State of Trip Generation
  5. 5. Current State • ITE dominant authority on Trip Generation – Hardcopy manual predominant source – Manual updates approx. every 5 years • OTISS digital format of ITE rates – Pay for use, not widely used • Other data sources, but less known/prevalent – Format inconsistences between various sources – No widely adopted data standard outside of ITE @TripChain 5
  6. 6. Recent ITE Trip Generation Activity • ITE Journal, July 2016 – ITE Statement on the Future Direction of Trip Generation – Advances in Urban Trip Generation articles – "Steps Forward” • ITE Urban and Person Trip Generation whitepaper – Fall 2016 • Online submission and improved data format – Fall 2016 – – Approx. 180 digital submissions between Oct. 16 and Jan. 17 • Recent Call for Data – January 2017 • Upcoming ITE Trip Generation Manual, 10th Edition – August 2017 – New data from over 1,700 sites – hardcopy, web app, data @TripChain 6

  11. 11. What is TripChain?
  12. 12. Project Objectives a.k.a. “What’s in it for you?” (Audience) • Make it easier to contribute new data; • Promote more robust usage between transportation professionals / authorities; and • Help professionals better plan for local situations using targeted trip generation rates. @TripChain 12
  13. 13. Digital Data Standard Portable, Web-Friendly @TripChain 14
  14. 14. Data Broadcast Peer-to-Peer, Near Real Time @TripChain 15
  15. 15. Common Data, Selected by Multiple Authorities @TripChain 16
  16. 16. How does TripChain work?
  17. 17. Understanding Definitions • Application Program Interface (API): – A set of routines, protocols, and tools for building software applications. An API specifies how software components should interact. A good API makes it easier to develop an application by providing all the building blocks needed. @TripChain 19
  18. 18. Application Programming Interface (API) @TripChain 20
  19. 19. Understanding Definitions • Blockchain Database: – A blockchain is a distributed database that is updated in near real time, stored in decentralized locations, and easy to monitor. It has a level of security that insures that no one party can modify a database entry, because, in a sense, everyone is watching. @TripChain 21
  20. 20. Create New Data Transaction @TripChain 22
  21. 21. Verify Digital Signature and Consensus @TripChain 23
  22. 22. Add Block to Existing Chain @TripChain 24
  23. 23. Enforce Data Continuity and Immutability @TripChain 25
  24. 24. Characteristics and Benefits of Blockchain Technology @TripChain Process Characteristics Blockchain Benefits Consensus between Multiple Parties Enhanced coordination and choreography between parties through a shared view of the latest data status. Reconciliation Master source of data instead of disparate data sources that require constant validation and reconciliation. Data Lineage (Temporal or 4D Data) Complete traceability, ensuring integrity of data that is continuously updated and maintained by multiple parties. Auditability Reliable and accurate audit trail with transparency of the party responsible for each data change. Source: Accenture Technology Vision 2016 26
