01

Key Findings

  • 01Motorcycles are the largest contributors to total emissions across all measured pollutants.
  • 02Average daily CO emissions reached approximately 1,315 kg/day, with peak levels exceeding 1,450 kg/day.
  • 03Traffic density strongly correlates with emission intensity.

Application

Design takeaway

When designing urban mobility solutions or policies, prioritize strategies that reduce motorcycle emissions, such as promoting electric two-wheelers or improving existing engine efficiency.

How to apply

When assessing the environmental impact of transportation systems, conduct detailed analyses to identify the most significant contributors to pollution, and tailor mitigation strategies accordingly.

Project actions

  • 01When researching environmental impacts, consider the 'hidden' contributors that might not be the most obvious.
  • 02Use data to justify design decisions, especially when addressing environmental concerns.
03

Method & Evidence

AimTo quantify the contribution of motorized vehicles, particularly motorcycles, to urban air pollution in Malang City.
MethodQuantitative analysis integrating traffic data with emission factor standards.
ProcedureTraffic data was collected using ALPR technology on major urban roads. Vehicle types were classified according to national regulations, and emissions of CO, NOx, PM, and SO2 were estimated using a Tier 1 approach.
ContextUrban air quality management in rapidly developing cities.

Variables

IV["Vehicle type (motorcycle, car, etc.)","Traffic density (peak vs. non-peak hours)"]
DV["Emissions of CO, NOx, PM, SO2 (kg/day)"]
CV["Road corridors studied","Emission factor standards used","Time of data collection"]
04

Strengths & Limitations

Strengths

  • +Integration of real-world traffic data with established emission standards.
  • +Focus on a specific, rapidly developing urban context.

Limitations

The accuracy of emission estimates depends heavily on the quality of traffic data and the chosen emission factors.

Reliability & validity

The reliability of the findings depends on the consistent operation of the ALPR system and the accuracy of the national emission factor standards. Validity is supported by the correlation between traffic density and emission intensity.

Think critically

How might the findings change if electric motorcycles become more prevalent in Malang City?

05

Design Principles

"Prioritize interventions based on the highest impact sources of environmental degradation."

Understanding the dominant sources of pollution is crucial for developing effective environmental strategies. This insight guides designers and policymakers to prioritize interventions targeting the most impactful vehicle types, leading to more efficient resource allocation for pollution control.

06

What This Means for Your Design

Cars and trucks aren't the only problem for air pollution in cities; lots of motorcycles actually cause more pollution overall because there are so many of them on the road.

How to use in your project
