The program, facilitated by the Chubu Economic Federation, focused on how psychological principles regarding perception, attention, and decision-making are applied to manage traffic flow, prevent accidents, and reduce wrong-way driving on expressways.
Integrating Behavioral Science into Traffic Infrastructure
The visit provided students with an overview of how NEXCO Central Japan (NEXCO中日本) maintains safety across its expressway network. According to representatives from the company’s Technology and Environmental Planning Department, the operation relies on a multidisciplinary approach, combining civil engineering with real-time traffic management.
At the Ichinomiya Road Control Center, staff monitor the highway 24 hours a day. The center acts as a hub for collecting data on traffic incidents, weather changes, and road conditions. This information is then used to coordinate with external agencies and control road equipment, ensuring that data-driven decisions are relayed to drivers effectively.
Psychology-Based Solutions for Road Safety
A significant portion of the program focused on the practical application of psychological concepts to mitigate common road hazards, such as traffic congestion and wrong-way driving.
According to officials from the Maintenance Planning Department, congestion often occurs at "sag" sections—where the road dips—and near tunnel entrances or highway junctions. These bottlenecks frequently result from subtle, unintentional speed reductions by drivers. To counter this, NEXCO Central Japan employs several environmental design strategies:
- Visual and Auditory Cues: Using light and sound signals to encourage drivers to maintain consistent speeds.
- Infrastructure Adjustments: Implementing additional lanes and utilizing color-coded pavement to guide traffic flow.
- Human-Centric Design: Applying principles of optical illusions and clear visual signage to help drivers understand complex road layouts instantly, reducing the cognitive load required to navigate merges and exits.
Managing Driver Behavior at Service Areas
The program also addressed the operational challenges of managing parking facilities. As congestion at service areas increases, the company is testing new management systems to optimize space.
Current initiatives include:
- Real-time Monitoring: Using image processing technology to track parking duration and identify occupancy trends.
- System Innovation: Conducting social experiments with parking reservation systems to manage peak demand.
- Behavioral Operations: Designing parking zones specifically for short-term use to improve turnover rates.
These efforts reflect a shift toward understanding driver behavior as a key component of infrastructure management. By analyzing how drivers utilize resting facilities, the company aims to improve the overall comfort and efficiency of the expressway network.
Future Career Development
The university intends to continue these partnerships to provide students with direct exposure to professional environments, helping them connect their academic research to real-world social infrastructure.
