CoAXs

Collaborative Accessibility-Based Stakeholder Engagement for Public Transportation Planning

What is CoAXs?

CoAXs is an interactive planning tool developed by a team at the Massachusetts Institute of Technology (MIT) that aims to enhance participation and creative problem-solving for planning public transport systems. CoAXs occupies a middle ground between detailed network editing and modeling software on the one hand, and presentation tools that use pre-calculated results for information delivery on the other.


CoAXs uses open data and free software to enable users to test new transportation scenarios in real time. Users can activate and deactivate selected hypothetical and existing transit routes; examine effects of changes such as in bus speeds or frequencies; and explore the impact of these changes on different locations in a region.


Central to the interface is a map which allows users to zoom in or out and focus on different areas of a city, helping to spatially understand the possible impacts (e.g., increased access to jobs) of potential public transport project features (e.g., dedicated bus lanes on a certain street). Customized versions of the tool have been tested in workshops in Boston, London, UK, and Santiago, Chile; and as an online version in Atlanta, San Francisco and New Orleans.

Research findings to date 

Barr Foundation: Boston BRT Workshops

Six workshops held in October 2015 in Boston’s Roxbury neighborhood tested community members’ reaction to bus rapid transit (BRT) concepts as part of the Barr Foundation’s Boston BRT initiative. Findings suggest:

· The workshops helped participants learn about the features of bus rapid transit.

· Participants viewed CoAXs as a relevant tool that generated credible results.

· CoAXs supported dialogue between participants, and the dialogue quality indicated some likelihood that participants would revisit fundamental goals, values and objectives (i.e., “double-loop” learning).

· Interaction with CoAXs, conversing with others, and questioning the tool and its assumptions facilitated learning amongst participants.

MISTI/MIT-Chile: Santiago Workshops

Two workshops –one with governmental officials and one with other stakeholders– were held in Santiago (in June 2017) to test CoAXs in a Latin-American context. The results suggest:


· CoAXs helped users better understand public transport projects and their impacts.

· CoAXs supported relevant transport planning conversations, generating collaboration and trust among participants.

· CoAXs enhanced users’ perception of transit project impacts at the metropolitan scale, rather than the local or municipal scale.

TransitCenter: Boston Workshops

In-person workshops (in October 2016), with members of LivableStreets Alliance in Boston, tested participants’ reactions to bus priority scenarios on certain corridors. Two different ways of showing project impacts were tested, travel time versus accessibility (to jobs). Findings suggest:

· Users considered the travel-time version easier to use.

· The accessibility version tended to induce broader discussions (e.g., regional-scale discussions such as housing affordability).

· Participants’ enthusiasm about potential bus priority improvements did not differ significantly between the accessibility and travel time versions of the tool.

· Group dialogue played a more important role in fostering enthusiasm for those using the accessibility version than the travel-time version.

· The accessibility version seemed more conducive to mitigating negative predispositions towards the transit projects.

TransitCenter: Remote Applications

A series of “remote” applications (i.e., with individuals logging in, on their own, via the web) was conducted in June 2017 in partnership with three transportation advocacy organizations – Advance Atlanta, Ride New Orleans and Walk San Francisco. Findings suggest:


· Users found the tool useful (e.g., for training advocates or utilizing results in advocacy) and usable.

· The use of CoAXs changed users’ perceived impacts of public transport system improvements.

· The user experience and incentives must be further improved for successful remote implementations; of those invited, few used the tool and they used it for relatively short periods of time (9 minutes on average).

Lessons learned for implementation

Interested in partnering with us?

Technical and organizational lessons learned from our experiences to date.


Think and Strategize First

Adapting CoAXs to a specific context is time consuming. Before starting to gather data, organizations should clearly define their vision and objectives for their stakeholder engagement campaign, use of the CoAXs tool, the transit projects of interest, and the types of “accessibility” (e.g., to job opportunities, healthcare facilities) to be analyzed.

Prioritize

In theory, CoAXs can be used to assess a number of different public transport scenarios and variations to them. In practice, the number of scenarios should be limited. Technical and time constraints naturally limit the scope of what can be considered in any practical application. The specifics should closely follow a strategic vision and objectives.

Prepare the Technical Requirements

CoAXs has four basic inputs: 1) General Transit Feed Specification (GTFS) files for the area’s public transit system, 2) geo-referenced data of the variables representing “opportunities” of interest to access (e.g., jobs), 3) technical details about the public transport projects of interest , and 4) shapefiles representing any proposed services and lines. An implementation team needs: proficiency in GIS and familiarity with GTFS, web development capabilities, and access to Conveyal's open-source software.

Design the Engagement Method(s)

In-person workshops tend to encourage enriching deliberations, where people can share experiences and doubts, question assumptions, and develop mutual understandings. That said, online engagement has the potential to engage a large number of people, in a low cost, low hassle way. A hybrid in-person/online engagement approach might also be worth exploring.

Provide Adequate Project Information

Even if the intended audience consists of people familiar with transportation planning, background information on the public transportation projects should be shared. This should include general information about the types of changes that can be explored in CoAXs and definitions of terms (e.g., headways, BRT, dwell times).

Capitalize on the Learning Opportunity

CoAXs is only one type of tool that can be used for enhancing engagement. Any organization should consider how CoAXs might fit within its broader suite of approaches and ultimate objectives. Once deciding that CoAXs (or a similar tool) might be right, the organization should consider using the experience as an experiment – to understand the impacts on its members, the organization itself, and its objectives.
