I-Transport LAB. Co., Ltd.

I-Transport LAB. Co., Ltd. (ITL) is a Japanese technology company specializing in traffic engineering and urban simulation. Founded in October 2000 as a University of Tokyo-origin venture by roughly ten university professors specializing in traffic engineering, the company is headquartered in Kanda-Surugadai, Chiyoda City, Tokyo. It describes itself as a "social implementation-oriented research company" that fuses expertise in traffic and urban engineering with in-house simulation technology. ITL's core business is the research, development and sale of traffic simulators, together with consulting on traffic and ITS (Intelligent Transport Systems) and traffic data processing and pedestrian-flow analysis. Its flagship products include SOUND, a wide-area road-network traffic-flow simulation system with more than 25 years of development; AVENUE, a street-network traffic-flow simulator based on the block-density method; MicroAVENUE, a microscopic traffic simulator that reproduces the behavior of individual vehicles; Smart Crowd, a crowd and evacuation simulation system that obtained certification from the Tokyo Fire Department in January 2026; and BTflow, a Bluetooth-sensor-based pedestrian-flow observation and data-acquisition system. The company also operates Traffic Scope, a technology that visualizes urban congestion in 1–2 km mesh grids, and Nowcast Simulation, a real-time traffic prediction technology. ITL serves government bodies such as the Ministry of Land, Infrastructure, Transport and Tourism (MLIT), prefectures and municipalities, construction consultants, and private facility operators. Its projects include traffic simulation support for the Tokyo 2020 Games, participation in MLIT's PLATEAU 3D city model project, and the Shonan Future Verse smart-city demonstration in the Shonan area in collaboration with NTT East, Keio University and the University of Tokyo under a NICT-commissioned research project. The company positions itself around the concept of "scientifically visualizing and solving complex traffic issues" and contributing to a sustainable future for urban and global environments.

I-Transport LAB. Co., Ltd. (ITL) was established in October 2000 in Shinjuku, Tokyo, as a University of Tokyo-origin venture. It was founded with capital contributions from approximately ten university professors specializing in traffic engineering. The company was created to advance and disseminate traffic simulation technology, at a time when simulation faced challenges such as data acquisition, model reproducibility and reliability, and interpretation of results. During the 2000s, ITL developed and commercialized its in-house simulation engines SOUND and AVENUE, and began providing them to the Ministry of Land, Infrastructure, Transport and Tourism (MLIT), prefectures, and construction consultants. Verification results were published through the Japan Society of Traffic Engineers' simulation clearinghouse. Over more than 25 years, the company continued to develop and improve these engines, building a track record in road planning, urban development, evacuation planning and related fields. In the 2020s, ITL expanded into digital twin and smart city applications. It commercially developed the pedestrian agent simulation Smart Crowd in collaboration with the University of Melbourne, and participated in MLIT's PLATEAU project for 3D city models. The company also worked on real-time prediction through Nowcast Simulation, traffic control using Beyond 5G, and the Shonan Future Verse smart-city demonstration in the Shonan area, an industry-academia collaboration with NTT East, Keio University and the University of Tokyo under a NICT-commissioned research project. In January 2026, Smart Crowd obtained certification from the Tokyo Fire Department under its new fire evacuation simulation evaluation system, allowing it to be used as a public basis for fire safety plans and building confirmation applications. The company has also provided large-scale traffic simulation support for the Tokyo 2020 Games. As of its company profile, ITL is headquartered in Kanda-Surugadai, Chiyoda City, Tokyo, with capital of 15 million yen. Its representative director and president is Hisatomo Hanabusa. The company employs doctoral degree holders and professional engineers, and its business covers research, development and sale of traffic simulators, consulting on traffic and ITS, and traffic data processing and pedestrian-flow analysis.

A social implementation-oriented research company that scientifically visualizes and solves complex traffic issues using data and models.

• SOUND

  Wide-area road-network traffic-flow simulation system for networks of several kilometers to several hundred kilometers, based on research from the University of Tokyo's Institute of Industrial Science, with over 25 years of development. Uses a Q-K granular mesoscopic model and supports dynamic route choice, signal control and environmental impact assessment.

• AVENUE

  Street-network traffic-flow simulation system for networks from a single intersection to several square kilometers. Uses the block-density method published in the Japan Society of Traffic Engineers' simulation clearinghouse, and supports signal control, traffic regulation and ITS effect evaluation.

• MicroAVENUE

  Microscopic traffic simulation that reproduces the behavior of individual vehicles at intersections, local streets and work zones, with 3D visualization. Supports mixed traffic evaluation with autonomous vehicles and new mobility such as electric kickboards.

• Smart Crowd

  Crowd and evacuation simulation system using an individual agent model to reproduce large-scale pedestrian flow and evacuation behavior. Certified by the Tokyo Fire Department in January 2026 under its fire evacuation simulation evaluation system, usable as a public basis for fire safety plans and building confirmation applications. Supports BIM/CAD import and reproduces arching phenomena and exit congestion.

• BTflow

  Pedestrian-flow observation and data-acquisition system using Bluetooth sensors installed indoors and outdoors to collect individual trajectories, dwell times and passing counts in real time. Data can be linked to Smart Crowd and pedestrian-flow simulation.
