Cristian Navas - Testing collaborative accessibility-based engagement tools: Santiago de Chile Case

  1. 1. Testing Collaborative Accessibility-Based Engagement Tools: Santiago de Chile Case Cristián Navas Duk | 2017 Msc. Urban Studies and Planning Candidate DUSP - MIT Cambridge, MA | August 2017 1
  2. 2. Agenda • Introduction: CoAXs tool and accessibility formulation • Research Questions and Objectives • Literature review: Engagement process and Metropolitanism • Experiment design and tool development • Results • Conclusions and future research 2
  3. 3. CoAXs • MIT Collaborative Accessibility-Based Stakeholder Engagement Tool  CoAXs. • CoAXs focus on accessibility, or potential connectivity to opportunities • Open-source, open data-based, web-based online platform. • Display the performance of public transportation systems. • Encourage the engagement of community and stakeholders groups in transport (transit) planning process 3
  4. 4. How CoAXs looks like? • Based on OSM • Developed for PEDs and Transit. • GTFS • Opportunity layers: Jobs location. 4
  5. 5. CoAXs Accesibility –Simple formulation, no need of demand modeling –Relation between spatial information and transit service supply D is the selected destination opportunity/activity type (e.g. jobs). M is the mode of travel (e.g. auto, transit GTFS). T is a time window for the trip (e.g. peak, off-peak). C is the cutoff time if a binary cumulative opportunity measure is used (e.g. maximum allowable journey time), see below. qj(D) number of opportunities of type D in zone j, Tij(M,T) is the typical time or generalized cost to travel from zone i to zone j by mode M at time T.
  6. 6. CoAXs Accesibility 3. Accesibilidad desde modelos no tradicionales (continuación) –C = 30 min –T= AM –D=Jobs –M=transit –ai=10 jobs i j
  7. 7. Research Questions and Objectives • Research questions: •How could Accessibility Based Visualization Tools (ABVT) be used to improve current engagement processes and advance to a more effective transportation planning? •Could ABVT tools encourage wider metropolitan (rather than local) discussions in a transport planning engagement process? 7
  8. 8. Research Questions and Objectives • Objectives: 1. Explain transport planning engagement process and their particularities in the context of Santiago de Chile. 2. Build a web CoAXs toolkit and design a simulated transit planning engagement process for tool testing in Santiago de Chile. 3. Develop a simulated participatory experience in Santiago for two different testing groups: Stakeholder and Decision Makers. 4. Analyze and evaluate the results of the testing experience. 5. Develop recommendations for new CoAXs testing experiences and further research. 8
  9. 9. Literature Review 1. Engagement process in Transportation Planning (1/2) – Poor public participation in Transportation Planning: Predict and Provide (PP) and Decide, Announce and Defend (DAD) traditional approaches  Division between Planning and Decision Making; increased gap with Transportation social aspects. – Traditional approaches characteristics  project or solution oriented and Technical language:  Non expert audience. – Consequences Traditional approach: Public Mistrust, NIMBY, Lack of Project Buy-in, and LACK of Collaboration across scales. 9
  10. 10. Literature Review 1. Engagement process in Transportation Planning (2/2) – Santiago’s Case: Example of institutional competition and lack of integration across scales (National, Region and Municipal). Example of poor public participation in planning  traditional TP approaches. – Data Visualization  Transport Planning has not leveraged Vis. Technology to participatory process: mostly are focused on the planners and engineers tools. Vis. tools still on PP or DAD approach (vis. Project oriented solutions) 10
  11. 11. Literature Review 2. Metropolitanism (1/2) – Metropolitan Planning  could generate better Transportation Planning • Better public transport services • Better coordination for transportation policy • Encouragement for sustainable urban development and mobility – The Challenge  Public engagement process at Metropolitan Scale. – The Opportunity  The use visualization tools. (CoAXs) 11
  12. 12. Experiment design and tool development 1. Experiment design (1/2) • Objective: Recreate a real participatory experience in the Chilean Context • Workshop design characteristics: • Two testing groups: Decision Makers (DM) and Stakeholders(SH) • 6-12 participants per workshop (20 total) • 3 facilitators: Street Design, Demand Forecasting, Urban Development. • 4 workshop staff: Data Collection, Technical Support, Room Set-up, Gral. Coord. • Visualization device: 75 inches touchscreen 12
  13. 13. Experiment design and tool development 1. Experiment design (2/2) • Workshop Activities • Preparation and Introduction  Materials, COUHES, Intro and Pre-survey • Basic Use and Coax Capabilities  CoAXs Atlanta • CoAXs Testing  Stgo’s Base scenario, Stgo’s Base-project comparison • CoAXs Evaluation  Post-survey and Debrief • Data Collection • Pre and Post Surveys • Tool interactions and conversations records (Staff) 13
  14. 14. Experiment design and tool development 2. Tool Development (1/1) • Tool features selection and new development • Based on SA previous CoAXs versions • Accessibility (isochrones) • Fix project multi-Selection (CoAXs Atlanta)  Stgo’s Transit Projects selection • New Opportunities: Jobs (total), Education (by ranking) and Health (by type) 14 Time Frame Operative Year Name Mode Origin - Destination (commune) Characteristics: Operative Information Short term 2018 Line 3 Subway La Reina - Quilicura Frequency: 2 min.

  21. 21. Survey Main Results • General workshop experience (2.4 post survey question) • Very positive responses among DM & SH • Participants largely agreed about: open discussion, others interest in diverse opinions, and support on groups recommendations (trust). • Tool evaluation: Usability and usefulness • Positive responses about usability and usefulness among DM & SH • Participants agreed that CoAXs provide a useful environment for collaborative work. • Participants agreed that CoAXs would support the kinds of conversations that the public needs to have about transport. • Friendly, for training, brings confidence, help to understand how travels is for others, etc. 21
  22. 22. Qualitative results • Tool interactions 22 Variable Decision Makers Stakeholders Total Participants 6 9 Total CoAXs Interactions 37 99 Total (potential) Interaction Time [min] 84 59 Interactions per Participant 6.17 11.00 Interactions per Minute [n/min] 0.44 1.68 Workshop Type of Interaction Point Move Marker Click/Tap/Zoom Decision Makers 13 13 11 Stakeholders 30 18 51 Workshop Interaction Interface Map Control Panel Decision Makers 29 8 Stakeholders 79 20 • SH Group largely interact with the tool • SH develop more advanced interactions • MAP interaction was preferred (3/4)
  23. 23. Conclusions and future research • Conclusions (1/2) • Experiment results confirmed the utility of CoAXs for: • Project impact understanding and project learning • Contribution to a good workshop experience • Provide a useful environment for collaborative work. • Support the kinds of conversations that the public needs to have about transport. “All of this positive results triggered by the use of CoAXs, promise (potentially) to improve the public engagement process, advancing through a more effective transportation planning” 23
  24. 24. Conclusions and future research • Conclusions (2/2) • Metropolitanism and CoAXs: • Experiment showed that this version of CoAXs is more likely to change perceptions in high scales (Metro Areas). • Comments during debrief activity corroborated that result. 24
  25. 25. Conclusions and future research • Future research • Metropolitanism and CoAXs. • Develop new regional analysis feature for expanding the actual origin point isochrone to areas (Coveyal’s regional analysis). • Expanding the experiment for more confident results. • Instead of developing special workshops for tool testing (having this first promising results), new testing experiences should be recommended as part of a real transportation planning process • Chilean Context application: intermedium cities transport planning and zoning municipal/metro planning studies 25
