62Complex's LiDAR Solution Adopted for Traffic Survey at Kuwana Station West Roundabout, Mie Prefecture

62Complex Co., Ltd. (Headquarters: Fukuoka City, Fukuoka Prefecture; CEO: Tsukasa Hashimoto; hereinafter "the Company") was commissioned by Chuden Kravis Co., Ltd. (Chubu Electric Power Group) to conduct measurement and analysis using LiDAR sensors for a traffic survey targeting the newly constructed roundabout (opened June 21, 2025) and the pre-existing temporary roundabout at the west exit of Kuwana Station in Kuwana City, Mie Prefecture. This survey was conducted as part of the "Co-Creation" smart city vision promoted jointly by Kuwana City and Chubu Electric Power Co., Ltd. The survey period spanned approximately four weeks from December 24, 2025, to January 20, 2026. Using five LiDAR units, the Company precisely collected data on vehicle inflow and outflow counts, time-of-day traffic volumes, and traffic flow patterns (OD), quantitatively visualizing the coexistence of both roundabouts and actual usage patterns after the new roundabout's opening.

Background

Kuwana City and Chubu Electric Power Co., Ltd. signed a comprehensive partnership agreement on March 28, 2024, and announced the smart city "Co-Creation" vision on November 6, 2024. Aiming to realize a "thrilling Kuwana," they are advancing initiatives to solve regional challenges and create new value using new technologies such as ICT (Source: Kuwana City and Chubu Electric Power Establish Smart City "Co-Creation" Vision).

Under this vision, following the opening of the free passage and elevated station building in 2020, the new roundabout at the west exit of Kuwana Station opened on June 21, 2025. The pre-existing temporary roundabout at the west exit had already been a primary access and drop-off point for station access and passenger pick-up before the new roundabout opened and continued to be used afterward. With both new and old roundabouts coexisting, understanding the actual flow of buses, taxis, and private vehicles, as well as the functional division between the two roundabouts, became a critical issue. Recognizing the need to objectively understand post-implementation usage patterns to inform and validate smart city policies, Chubu Electric Power Group tasked its subsidiary, Chuden Kravis Co., Ltd., with conducting a traffic survey around Kuwana Station. In addition to its own AI camera-based measurement service "Mimamori Pole," Chuden Kravis commissioned the Company to conduct LiDAR-based measurement to complement camera blind spots and capture broader traffic flow patterns.

The Company's Role

The Company provides traffic analysis solutions leveraging LiDAR sensors, which excel in 3D spatial measurement. In this project, five LiDAR sensors were installed at the new and temporary roundabouts at Kuwana Station's west exit. The system automatically analyzed vehicle inflow and outflow counts by direction, time-of-day fluctuations, and traffic flow patterns (OD), distinguishing vehicles from pedestrians and bicycles. Stable measurement was possible even in nighttime and backlit conditions, which are difficult for AI cameras to capture, contributing to continuous 24-hour data collection and high-precision traffic flow analysis.

Survey Overview

Main Highlights of LiDAR Measurement

1. High Precision IN/OUT Consistency

At the temporary roundabout, the IN/OUT error rate for inflow and outflow counts was recorded at 0.75%, achieving significantly higher accuracy than standard tolerance levels in typical traffic surveys.

At the new roundabout, some areas showed increased error due to installation environment factors (blind spots, obstructions), providing valuable insights for future installation optimization.

2. Visualization of Functional Differences Between New and Old Roundabouts

The new roundabout showed approximately 1,059 vehicles per day on weekdays and about 1,422 on weekends, indicating a 34% increase in weekend usage. This confirms its role as a multi-purpose hub including commercial activities and passenger drop-offs.

The temporary roundabout showed approximately 1,040 vehicles per day on weekdays and about 1,072 on weekends, with almost no difference between days, functioning as a steady commuter and student access route to the station.

3. Application to Traffic Flow (OD) and Congestion Prediction

Of the new roundabout's inflows and outflows, the west side of the station (city center side) accounted for approximately 45% of inflows and 54% of outflows, confirming it as the main traffic corridor.

A simulation was conducted to predict time-based changes in congestion levels based on the usage patterns of both roundabouts, contributing to discussions on operational policies for each roundabout and future station-front development plans.

Future Developments

The Company will expand its high-precision traffic measurement and traffic flow analysis solutions using LiDAR to key transportation nodes nationwide, including station plazas, redevelopment areas, commercial districts, and intersections. By combining complementary use with AI cameras and integrating simulations and OD analysis using collected data, the Company will provide quantitative data to support decision-making by municipalities, transportation operators, and development companies, contributing to the advancement of smart cities and MaaS.
