## 5 Conclusions  
To enhance the effectiveness of PUPs, several strategic recommendations can be implemented:  
* Strategies to bridge the awareness-usage gap: As mentioned above, awareness of PUPs is high, but their usage remains modest. To bridge this gap, educational campaigns highlighting PUPs' benefits (convenience, cost-effectiveness, environmental friendliness) could be implemented. Collaboration with e-commerce retailers offering PUP incentives and expanding the PUPs network to more convenient locations, especially near residential areas, could further entice users. * Enhancing security and user comfort: Security concerns surfaced, as some users felt it was unsafe to use PUPs. To address this issue, improving lighting and establishing a dedicated customer support channel for PUP-related inquiries or concerns will allow users to report issues or seek assistance properly. By implementing a multi-layered approach that combines physical security measures, clear communication, and user-friendly technology, PUP services can become a more secure and convenient option for e-commerce deliveries. * Tailoring PUP services to demographics: Different demographics have varying needs and preferences regarding PUPs. Offering a wider variety of PUP locations, including those close to residential areas for proximity-conscious users, is essential. Partnering with businesses frequented by younger demographics to establish PUP locations within those businesses could be explored. To better understand PUPs' environmental and economic benefits, future research should focus on conducting a comprehensive life cycle assessment to compare the environmental impact of PUPs versus home deliveries. This analysis should extend beyond fuel consumption and consider factors like packaging materials, infrastructure requirements, and autonomous-energy PUPs. Moreover, future research should focus on exploring the potential for integrating PUPs with smart city technologies. This could involve real-time traffic data to optimize delivery routes, smart locker systems for secure and convenient pick-up, or integration with public transportation networks to encourage users to combine picking up their goods with their daily commutes. Finally, crowd shipping should be explored as a solution for those that are not willing to use PUPs. Generation Z, known for their digital savviness and environmentally conscious mindsets, can play a crucial role in the adoption and optimization of these technologies. Their preference for sustainable practices and convenience aligns well with the integration of smart city technologies and alternative delivery methods. Understanding the behavior and preferences of Gen Z consumers can provide valuable insights for designing PUP systems that meet their expectations and encourage broader adoption. Incorporating Gen Z's feedback and usage patterns will be essential in creating efficient, user-friendly, and eco-friendly PUP solutions. To improve the effectiveness of PUPs, several initiatives can be implemented. Training and information activities include conducting interactive workshops and webinars to educate users on PUPs' benefits and the efficient use of e-commerce platforms, developing specialized training programs for service managers to understand user behavior and integrate feedback, and creating comprehensive guides and FAQs. Sustainable service activities suggest promoting the use of eco-friendly vehicles for last-mile deliveries; implementing policies to ensure fair wages and safe working conditions for delivery riders; and advocating for the development of bike lanes, pedestrian pathways, and dedicated PUP access points. The validity and scope of the opinion poll involve clearly stating the study's basis using an opinion poll and acknowledging potential biases while contextualizing findings and highlighting the need for further research to validate and expand upon results.
