Automated vehicles: A double-edged sword for environmental impact

Transportation Research Part A Policy and Practice · 2016

Key Findings

01Vehicle automation can influence energy consumption and GHG emissions through changes in travel demand, vehicle design, operating profiles, and fuel choices.
02Depending on which effects dominate, automation could plausibly reduce road transport GHG emissions and energy use by nearly half, or nearly double them.
03Many potential energy-reduction benefits may be realized with partial automation, while major energy/emission downside risks are more likely with full automation.

Application

Design takeaway

When designing automated vehicle systems, prioritize features and operational strategies that actively promote energy efficiency and minimize unintended increases in travel demand.

How to apply

When developing concepts for automated vehicles, conduct scenario planning to assess both optimistic and pessimistic environmental outcomes. Incorporate design elements that encourage shared mobility and discourage excessive single-occupancy trips.

Project actions

01When researching automated vehicle technology, consider its potential impact on user behavior and overall energy consumption.
02Explore how design choices can influence the environmental outcomes of automated systems.

Method & Evidence

AimTo identify and quantify the mechanisms through which vehicle automation influences travel demand, vehicle design, operating profiles, and fuel choices, and to assess their net effect on greenhouse gas emissions and energy consumption.

MethodLiterature review and quantitative analysis (engineering and economic modeling).

ProcedureThe researchers reviewed existing literature to estimate the energy impacts of various automation-driven mechanisms. Where literature was insufficient, they developed their own estimates using engineering and economic analysis. They then synthesized these findings to quantify potential impacts on U.S. light-duty and heavy-duty vehicle greenhouse gas emissions.

ContextTransportation sector, specifically road vehicles.

Variables

IV["Level of vehicle automation (partial vs. full)","Changes in travel demand","Vehicle design modifications","Vehicle operating profiles","Fuel choices"]

DV["Greenhouse gas (GHG) emissions","Energy consumption"]

CV["U.S. light-duty and heavy-duty vehicle fleet","Focus on travel-related impacts"]

Strengths & Limitations

Strengths

+Comprehensive analysis of multiple impact mechanisms.
+Quantification of potential impacts on a common basis (percentage change in GHG emissions).

Limitations

The actual impact of automated vehicles will depend on many factors not fully predictable, such as government regulations, public acceptance, and the pace of technological development.

Reliability & validity

The study's validity relies on the accuracy of the literature reviewed and the assumptions made in the engineering and economic analyses. Reliability is enhanced by using a coherent decomposition framework to synthesize findings.

Think critically

Given the potential for both positive and negative environmental impacts, what design strategies can be employed to ensure that the development and deployment of automated vehicles lead to net environmental benefits?

Design Principles

"Design for systemic sustainability: Consider the broader environmental consequences of technological innovation beyond the immediate product."

Understanding the multifaceted impacts of vehicle automation is crucial for designers and engineers developing future transportation systems. This insight highlights the need to consider not just the technology itself, but its broader systemic effects on user behavior and infrastructure.

What This Means for Your Design

Self-driving cars could either be great for the environment or really bad for it, depending on how we use them and design them.

How to use in your project

1.Use this research to justify the importance of considering environmental impacts in your design project, especially if it involves new technologies or automation.
