Summary
Government subsidies and improved data management strategies can foster cooperation in connected transportation systems. Enhancing data value, sharing, and protection encourages collaboration, while high risk costs deter it, especially for intelligent connected vehicle manufacturers.
Area of Science:
- Intelligent Transportation Systems
- Game Theory
- Behavioral Economics
Background:
- Vehicle-Road-Cloud (VRC) integration is crucial for intelligent transportation, but cooperation is challenged by data security, cost-benefit asymmetry, and stakeholder rationality.
- Limited research exists on how value perception and risk attitudes influence cooperation in data-driven VRC ecosystems.
Purpose of the Study:
- To model the evolutionary game dynamics of cooperation in VRC ecosystems.
- To investigate the impact of behavioral preferences (Prospect Theory) and government subsidies on cooperative strategies.
Main Methods:
- Development of a three-party evolutionary game model (ICV manufacturers, cloud platforms, government).
- Incorporation of Prospect Theory for behavioral preferences under uncertainty.
- Introduction of a dynamic government subsidy mechanism.
- Application of replicator dynamics and numerical simulations.
Main Results:
- Dynamic government subsidies effectively promote ecological cooperation in VRC systems.
- Higher data value conversion efficiency, data sharing intensity, and data protection levels enhance cooperation willingness.
- Increased data-related risk costs significantly inhibit cooperation, particularly for ICV manufacturers.
Conclusions:
- Behavioral insights are crucial for understanding multi-agent coordination in VRC integration.
- Policy interventions, like dynamic subsidies, and strategic data management are key to fostering sustainable cooperation in intelligent transportation ecosystems.

01:20Evolutionary Psychology
Evolutionary psychology explores the origins of human behavior and mental processes by framing them within the context of natural selection, a theory famously propounded by Charles Darwin. This field asserts that many behaviors common across human societies — ranging from instinctive fear reactions to complex social interactions — arose as evolutionary adaptations. These adaptations enhanced the survival and reproductive success of our ancestors, thereby becoming embedded in the human psyche...
01:20Decision Making
Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...

02:06Social Exchange Theory
We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).
01:26Social Exchange Theory
As formulated by John Thibaut and Harold Kelley, Social Exchange Theory explains human relationships as economic-like exchanges that maximize rewards and minimize costs. This theory suggests that individuals engage in relationships to gain benefits and reduce burdens, similar to economic transactions. It has been widely applied to various types of relationships, including romantic, professional, and social interactions.Rewards and Costs in RelationshipsRelationship rewards include emotional...
01:24Social Foundations of Self I: Play and Game
The development of self in children is deeply rooted in social interactions, mainly through stages of play and structured games. These stages, outlined by sociologist George Herbert Mead, illustrate how children progressively learn to understand and adopt social roles, forming a cohesive sense of self.The Play Stage: Imitation and Simple Role-TakingIn the early years of childhood, the play stage is characterized by imitative behavior, where children engage in role-playing based on familiar...
01:09Decision Making: P-value Method
The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can have a...
