Chemical pesticides are a serious impediment to agricultural sustainability. A large-scale reduction in their use to secure food supplies requires more innovative and flexible production systems. Pesticide-free production standards bring together the strengths of all participants in the food value chain and could be the catalyst for this transition. Using a choice experiment approach and green tea as an example, this study investigated consumers’ preferences for organic and pesticide-free labels. According to the findings, organic and pesticide-free labels and brands are all major factors that affect consumers’ purchase decisions. Consumers are more willing to pay for organic labels than pesticide-free labels. There is a substitution effect between organic labels and pesticide-free labels. Complementary effects exist between organic labels and national brands, pesticide-free labels, and national brands. Consumer trust has an impact on consumers’ choice of organic labels and pesticide-free labels. The use of pesticide-free labels is an alternate approach for small- and medium-sized businesses in a specific market to lower the cost of organic certification.

“…V2I is expected to come first, before V2V is taken up. The ability of a vehicle to perform V2V communication delivers more value when more vehicles also have this ability, a network effect described by Maeng et al (2020). If the situation is left entirely to the market, it can result in a negative situation where everyone waits for others to invest in such equipment first.…”

What we didMotorway crashes kill over 200 people in Korea each year. Matching the average safety performance observed across Germany, Japan, the Netherlands and the United Kingdom would halve the number of motorway deaths. This report reviewed international best practices in motorway safety across ten countries to determine which might be best suited to making Korea's motorways safer. It offers recommendations for an action plan to 2030, taking into account the expected uptake of connected and automated vehicles.The International Transport Forum (ITF) engaged with over 40 experts and organisations in Korea and ten other ITF countries:

“…Currently, the Korean government is focusing on developing and introducing new AVrelated technologies [4]. Examples include V2V (Vehicle-to-Vehicle), which enables AVs to communicate with each other, and V2I (Vehicle-to-Infrastructure), which enables AVs to communicate with infrastructure in real time [5].…”

Effects of Exclusive Lanes for Autonomous Vehicles on Urban Expressways under Mixed Traffic of Autonomous and Human-Driven Vehicles

Autonomous vehicles (AVs) are expected to be seen easily on our roads, providing benefits to society in the future. However, due to the challenges faced such as technical and regulatory issues, it will take a long time to reach 100% AVs, suggesting the coexistence of AVs and human-driven vehicles (HVs) for a substantial time. This coexistence of the mixed traffic of AVs and HVs may affect network performances in urban areas. Under this circumstance, to promote the rapid advancement of AV technology, transportation authorities are considering introducing AV-exclusive lanes. This study evaluates AV lane operation scenarios with mixed traffic consisting of both AVs and HVs. We utilized a macroscopic traffic simulation-based approach to measure the effects of AV lanes on two urban expressways in Seoul, South Korea. We varied the market penetration rate (MPR) from 10 to 80% in 10% increments. The simulation results indicate that the impact of exclusive lanes can be either negligible or beneficial depending on the characteristics of the roads. The results also showed that, in terms of the efficient use of road capacity, AV lanes should be introduced when the MPR reaches at least 20 to 30%. The results also showed that the capacity gain effect is more sensitive over a lower MPR range. We expect this study to not only enhance policy makers’ and planners’ fundamental understanding of the early stages of AV-exclusive lanes, but also help them prepare a large-scale urban network structure in the future.
