CART Codes 2024
CART Codes 2024 Hackathon 

The Climate Action Research for Transportation (CART) Network hosted it's inaugural CART Codes 2024 | Hack How We Move, in Halifax, NS, on February 10-11, 2024 as part of their five-year project funded by the Climate Action and Awareness Fund from Environment and Climate Change Canada. The event was spearheaded by Dalhousie Transportation Collaboratory (DalTRAC) and the Intelligent Automation in Software EngineeRing (RAISE) Lab. CART Codes was a fully in-person 24-hour event which generated collaboration amongst computer science, engineering, and planning disciplines. Students worked in teams of up to four individuals to hack and model how we move.

As of 2022, the transportation sectors is one of the major sources of greenhouse gas (GHG) emissions which comprises 24% of total GHG in Canada. Federal, provincial, and municipal governments have already adopted various climate action policies such as vehicle electrification, carbon trading, among others to tackle climate change impacts on residents and infrastructure. To strengthen Canada's effort in achieving 2050 net-zero emissions, the use of sustainable transportation and tracking individual level carbon footprints are critical. Data collection and evidence-based decision making are more important now than ever to establish benchmarks, quantify progress, and enact policy. The complexity of these problems demand collective action to enhance technical capacity of solving climate change challenged and inform proactive decisions and policies at the individual, local, and national levels.

CART Codes focused on climate change actions within Nova Scotia by producing valuable data tools that aided in the advancement of activity-based travel data collection and modelling that had already been established by DalTRAC. Hackers were tasked with developing methods/tools/games/applications as a solution to the project streams identified:

STREAM 1: Mobile Application Development ​

STREAM 2: Data Mining & Predictive Modelling

STREAM 3: City Modelling for Urban Games

STREAM 4: Design your Sustainable City

The 24-hour hackathon showcased team work, hard work, and innovation. Teams came up with exciting and innovation solutions to track users mode choices, distance and time travelled, and created accessible systems to incentives users to make eco-friendly choices.


CART Codes 2024 judges were carefully selected to reflect the computer science, engineering, and planning disciplines participating in the event. Hackers had the opportunity Judges included:
