Unity-Vissim Cosimulation environment development for Human-in-the-loop test Existing human-in-the-loop (HIL) test systems have limitations in providing a realistic traffic environment. Microsimulation(VISSIM) is mainly used for traffic flow analysis because it embeds models that reflect general human driving behaviors(such as car-following and lane change). By integrating the two software, the cosimulation environment was built to analyze […]

Traffic volume imputation based on multi-source data collection system Traffic detectors collect traffic data to understand the flow of traffic on a city scale, which can help build an efficient traffic management system or deliver useful traffic information to road users for better decision-making. However, various types of missing data occur depending on the data […]

Interactive driving behavior in overtaking situation Existing studies on overtaking behavior have only examined it from the perspective of the overtaking vehicle, with limited consideration for the risk level of the vehicle approaching from the opposite side. The multiagent simulator helped collect a realistic overtaking driving dataset without compromising safety. The collected data was preprocessed […]

Optimized Signal plan development Develop an optimized traffic signal plan using the Neighbor Dueling Deep Q-Network (NDDQN) algorithm, which considers neighboring intersections. The algorithm controls four neighboring intersections simultaneously by determining signal actions with the goal of reducing emissions as a reward.

  This research is to integrate communication, traffic and driver behaviours, vehicle dynamics, and environment conditions in a unison framework to increase safety, reliability, and performance of connected and automated vehicles within a mix traffic condition. To achieve this goal, TUPA has been developing an architecture that leverages existing tools like VISSIM, Driving simulator, Virtual […]

The dashboard below was developed through Elastic open source software using the Seoul metro passenger flow data in 2014. Data visualization has been important in democratizing data and analytics and making data-driven insights available to workers throughout an organization. Data visualization also plays an important role in big data and advanced analytics projects. As a […]

We utilized TurtleBot3 which adopts ROBOTIS smart actuator Dynamixel for driving. TurtleBot3 is a ROS-based mobile robot. We customized it to reconstruct the mechanical parts and use optional parts such as the computer and sensor. SLAM, Navigation and Manipulation, makes it to build a map and can drive around the room. Also, it can be controlled remotely from a laptop, […]

Research Aim To provide empirical evidence on the relationship between built environment and public sharing bike flow in Suzhou, China. Research Objectives To examine the global impacts of built environment on public sharing bike flow. To understand the effects of spatial variation of those built environment on public sharing bike flow Study Area The study […]

INTRODUCTION Transportation data is of great importance for intelligent transportation system. Missing data problems are inevitable during data collection. Challenges in existing imputation methods: potential useful information is not efficiently used in the modeling process; methods considering temporal correlation usually assuming that linear relationships exist between observed variables and latent variables; most techniques fail to […]

Intro It’s not easy to pick up this background image for the post. It shows the Manhattan Peninsula, New York, and the sky reflects the buildings on the ground. This fantasy scene reminds me the complex relationship between space and time, which closely related to the topic of this article: Spatiotemporal forecasting of traffic by […]

The lane change behaviour is not only impacted by the blockage but also the surrounding traffic.  The combination of these two impacts determines the subject vehicle lane change execution behaviour: i.e. to either Continue lane change execution or Not Continue lane change execution. We developed the lane change execution model based on the model framework, […]

The bicycle sharing program in Suzhou encourages people to participate in smart transport. How does Suzhou bike sharing system work?

Authored by Wang, Chen and Kim The bike-sharing service has brought many conveniences to citizens and served as an effective supplement to mass transit system. For docked bike-sharing service, each docking station has the fixed spots to store bikes and stations could be empty or saturated at some time. Bike-sharing operators would redistribute bikes between stations […]

A big achievement on research! Monash university, Institute of Advanced Vehicle technology and JITRI secured research funding of 4 million RMB( AU$ 760,000). The project title is Green Travel Models in Smart Cities: Coordination studies and Integration Platform Project. The research is led by Dr. Inhi Kim, Prof. Terry Liu from SEU and Prof. Yifan […]

China’s Plan To Open Up Gated Communities. Can opening the gated community mitigates traffic congestion in China?

We developed a Wechat embedded application for helping police officers in China reduce their work load in issuing illegal parking tickets on site. The application is designed for public to take a photo of the plate number of the illegal parking vehicle then simultaneously stores information such as the plate number, location, time, and a type […]

What causes road rage in China? How can it be measured? And what is the solutions to this issue?

A potential in ITS application to predict urban railway level crossing delays

This study shows availability of using simulation to evaluate the areas in train station. The simulation can identify which areas need to be revisited and reconsidered in order to enhance customer satisfaction and safety in the building.
