Transforming Urban Infrastructure for Equitable EV Adoption
As cities worldwide accelerate toward electric transportation, a groundbreaking approach is emerging that could solve one of the most persistent challenges in EV adoption: charging accessibility for urban residents without private parking. Researchers from Penn State have developed a framework to convert existing streetlights into functional EV charging stations, creating what could become the backbone of urban electric mobility.

The Equity Challenge in EV Infrastructure
“The motivation for this work comes from the fact that many apartment and multi-unit dwelling residents, particularly in urban and downtown areas, lack access to dedicated home EV chargers, since they don’t have the privilege of owning a garage,” explained Xianbiao Hu from Penn State. This fundamental inequity has created significant barriers to widespread EV adoption, particularly in dense urban environments where off-street parking is scarce.
While global supply chain challenges continue to affect various sectors, the EV charging infrastructure faces its own unique implementation hurdles that extend beyond mere equipment availability.
A Three-Pronged Framework for Implementation
The research team established a comprehensive framework examining demand, feasibility, and community benefits to guide municipal implementation. Their methodology began with a sophisticated two-step site selection strategy: first identifying areas with the highest charging demand, then layering in equity considerations to ensure benefits reach underserved communities.
Using advanced AI models trained on multiple data points including land use patterns, existing station density, points of interest, and traffic volume, researchers generated data-driven maps of ideal charging locations. This approach represents a significant advancement in how cities can plan infrastructure projects, similar to how manufacturing innovations are transforming production processes across industries.
Real-World Testing and Environmental Impact
The team validated their approach through practical implementation, retrofitting 23 streetlights in Kansas City with EV charging capabilities. The results demonstrated not only technical viability but significant environmental advantages. Compared to conventional charging stations, streetlight chargers reduced gasoline consumption by 11.94% and greenhouse gas emissions by 11.24% more effectively.
Interestingly, vehicles tended to have shorter charging sessions at streetlight stations, likely due to curbside parking limitations or associated costs. However, even with these shorter durations, the environmental benefits remained substantial, proving the efficiency of this distributed charging approach.
Infrastructure Advantages and Economic Benefits
Streetlight chargers offer multiple practical advantages that make them particularly suitable for urban environments:
- Existing Infrastructure: Utilizing already-installed poles and power lines significantly reduces installation costs and complexity
- Optimal Placement: Streetlights are naturally positioned curbside, exactly where parking occurs
- Municipal Management: City-owned infrastructure simplifies maintenance and operations
- Job Creation: Local installation and management can stimulate economic growth
These benefits align with broader industry developments in smart city infrastructure and sustainable technology implementation.
Future Research Directions
The research team plans to enhance their models by incorporating socioeconomic data and weather information. Socioeconomic factors will help identify communities that might otherwise be overlooked in EV infrastructure planning, ensuring that charging access reaches those who need it most. Weather data integration will account for temperature impacts on battery performance and driving patterns, creating more resilient charging networks.
This comprehensive approach to urban infrastructure transformation represents a significant step toward making clean mobility accessible to all urban residents, regardless of housing type or income level.
Broader Implications for Smart Cities
The streetlight charging concept exemplifies how cities can leverage existing assets to address emerging needs. As urban centers continue to evolve, this type of multi-functional infrastructure represents the future of smart city planning. The approach demonstrates how thoughtful integration of technology into everyday urban elements can create more sustainable, equitable, and efficient cities.
As with many recent technology innovations, the most impactful solutions often involve reimagining how existing systems can serve new purposes. The streetlight EV charging initiative not only addresses immediate charging needs but also points toward a future where urban infrastructure serves multiple functions efficiently and equitably.
Supported by the US Department of Energy and developed in collaboration with the Kansas City Metro Energy Center, local utility companies, and the National Renewable Energy Laboratory, this research provides a replicable blueprint for cities worldwide seeking to expand EV access while maximizing existing resources and promoting environmental justice.
