DDMA 2025 Montréal workshop report published

February 23, 2026

We are very pleased to share that the report from the Data-Driven Mobility Analytics (DDMA) Workshop 2025 – Montréal has now been published and is openly available.

https://doi.org/10.17605/OSF.IO/ZXU8Q

This report documents the outcomes of the workshop held on October 27, 2025, at McGill University, which was organized by our lab in collaboration with Henrikki Tenkanen (Aalto University) and Marina Toger (Uppsala University). As organizers, we are incredibly happy to finally see this report online.

About the Workshop

The Montréal workshop was the second event in the DDMA series, following the inaugural workshop in Espoo, Finland (in conjunction with the 19th International Conference on Location Based Services. It brought together 46 participants from across Canada, the United States, and Europe, representing expertise in transportation, urban studies, spatial data science, public health, and policy. The goal of the workshop series is to build a sustained, interdisciplinary community focused on advancing the responsible and policy-relevant use of mobility data and analytics. Rather than focusing on isolated case studies, the series aims to support shared infrastructure, reusable analytical frameworks, and collective governance around mobility data.

Key Themes from the Workshop

Through invited talks, lightning presentations, and structured breakout discussions, participants identified several recurring themes that shape the future of data-driven mobility analytics. These themes were synthesized from collaborative sticky-note discussions and refined by the organizers (with AI-assisted clustering to support aggregation, followed by careful human review and restructuring).

Fragmentation, Access, and Interoperability of Mobility Data.
Expanding Beyond Traditional Quantitative Data
Bridging Advanced Analytics and Real-World Practice
Reducing Duplication Through Shared Infrastructure
Building a Sustainable Mobility Analytics Collective

Outcomes and Next Steps

The workshop strengthened cross-institutional connections and helped clarify shared research priorities We are aiming to follow up this report with (1) A vision paper aimed at an academic audience and (2) A policy-oriented document translating workshop insights into actionable guidance for decision-makers. There was also strong interest in continuing the workshop series and formalizing a collaborative framework for the DDMA community.

abstract = {Special events, such as festivals, parades, and protests, can cause sudden surges or disruptions in travel demand, thereby placing stress on transportation systems. As shared micromobility becomes an increasingly important part of urban transportation, understanding how these events affect its ridership is crucial for ensuring safety, efficiency, and sustainability. In this study, we investigate the causal impacts of various event types by applying Double Machine Learning (DML) to high-resolution shared micromobility trip data (e-bikes and e-scooters) and multi-source event records in Washington, D.C. These events include government-authorized large events, independently organized small events, and government-registered protests. Our results show that many events have far stronger actual influences on shared micromobility than correlational analysis suggests, as confounding factors can mask their actual impact. For instance, festivals show four to seven times greater impact under causal estimation. We also find that the increase in gas prices suppresses discretionary travel, resulting in reduced shared micromobility usage during events. Another key insight is the different demand mechanisms: large events interact with temporal and built environment features to boost ridership, whereas small events are primarily influenced by temporal features, such as event duration and weather, with little influence from infrastructure factors. These findings highlight the need for tailored policies, including infrastructure investment for large events and operational incentives for smaller ones. This research provides a causal foundation for urban mobility planning, supporting the development of more resilient and efficient transportation systems in event-dense urban areas.},

abstract = {Many cities today are redesigning their streetscapes to redress the historical privilege afforded to the automobile in planning and policy. Much streetscape redesign is around transport infrastructure space, which largely prioritizes car travel and marginalizes other travel modes. Attempts by planners and policy makers to this end often are met with public opposition by advocates of the car, protesting about losing space on the street. This is empirically investigated with the case of Montréal by determining the allocation of street space to transport infrastructures, deriving measures of infrastructure space per traveller, and devising an Equal Infrastructure Allocation score to measure the imbalance between infrastructure provision per travel mode. Per borough, the distribution of transport infrastructure is examined, alongside correlations with demographic, socio-economic, land use, and crash rate variables. Potential scenarios of significant micromobility infrastructure improvement are modelled to test how infrastructure space apportionment per mode changes. This investigation discovers that even large improvements to micromobility infrastructure have a minor effect on space allocated to automobiles. Equal Infrastructure Allocation score and associated indicators are presented as useful tools for planners and policy makers implementing micromobility infrastructure projects, to better communicate with the public and address potential opposition.  },
