Researchers Measure Traffic Emissions, to the Block, in Real-Time

Researchers measure traffic emissions, to the block, in real-time

In a study focused on New York City, MIT researchers have shown that existing sensors and mobile data can be used to generate a near real-time, high-resolution picture of auto emissions, which could be used to develop local transportation and decarbonization policies. The paper, "Ubiquitous Data-driven Framework for Traffic Emission Estimation and Policy Evaluation," is published in Nature Sustainability.

Real-Time Data Is Redefining Urban Emissions Mapping and Transport Policy Real-Time Data Is Redefining Urban Emissions Mapping and Transport Policy

Real-Time Data Is Redefining Urban Emissions Mapping and Transport Policy Cities have long struggled with a fundamental blind spot in transport planning: understanding exactly where, when, and how vehicle emissions occur. Traditional emissions inventories tend to rely on averaged data, periodic sampling, or broad modelling assumptions. While useful at a strategic level, these approaches often fall short when policymakers need to make precise, lo…

MIT Researchers Track Real-Time Traffic Emissions at the Block Level

In the bustling streets of New York City, a groundbreaking study led by researchers from the MIT Senseable City Lab has demonstrated a revolutionary approach to monitoring urban automobile emissions through the synthesis of existing sensor networks and mobile phone data. This innovative method transcends traditional techniques by delivering near real-time, high-resolution emission maps that […]
