"Construction VR simulation during bridge repair" SHO-BOND Holdings Co., Ltd.
In order to improve workability, it is important to accurately grasp the on-site situation and reflect it in the plan. This time, we collected point cloud data before the construction work, and modeled the parts accurately from the design drawings to express the on-site conditions. Then we expressed the assumed construction contents and examined the workability.
The animation "概要" scans environments around the construction site and the examples of replacement of bearings. In the scenarios "シナリオ：P4－A～D" and "シナリオ：P5－A～C", viewers can see the details of the construction simulation up close. The simulation is an easy to understand explanation material, showing a series of construction methods in 3D from anchor drilling to chipping. In the animation "クレーン走行", a crane moving along the narrow agricultural road can be checked from both the 3D and 2D view.

"Simulator for remote control training" Kyushu Technical Office, Kyushu Regional Development Bureau, Ministry of Land, Infrastructure, Transport and Tourism
Building a reconstruction of the area around Aso Ohashi, which collapsed due to the 2016 Kumamoto earthquake.The photo data is an aerial photograph of the actual disaster site, so that the damages caused at that time can be understood. Using this VR data, we are constructing a remote control training simulator for compact type backhoe for the purpose of initial response in the event of a disaster by connecting a remote operation controller.
By executing the scenario "遠隔操縦訓練概要", viewers can see the operation procedure using the actual equipment, notes in the preparation stage, and the explanation of VR simulation. The scenario "VR走行シーン" shows the operation training. In addition, in the scenario "重機操縦体験" viewers can operate the basic movements of heavy machines and driving in the VR space reproducing the real disaster site.
"VR data for driving reaction test" DENSO Corporation
VR simulation to verify the speed of the driver's reaction to people and bicycles jumping out at intersections while driving a car. By combining a collision-free dummy and a colliding target, about 160 types of various conditions such as the color, size, and timing of the object are set, and the time lag between the driver sensing the danger of collision and the reaction is verified.
This data let viewers experience the scenarios used in the experiments to test the driver's reaction. In the scenario "説明1", viewers can see the purpose, overview, and method of the experiment and experience the experiment events after that. The scenario "セッション1" starts from the testing event including 40 patterns situation. The angle of view setting and interior structure is special-made for the experiment.
"Road design for "Changing western highways to urban roads" by VR" Seoul Metropolitan Government Infrastructure Headquarters
The city of Seoul is planning to change the western highway to an urban road due to problems such as traffic congestion, environmental pollution, lack of parking lots, and low access rate. In order to solve problems that are difficult to solve with 2D design drawings, we discussed many design issues while checking with UC-win/Road. We review the visibility of intersections, the width of bicycle roads, and the visibility of structures and sound insulation walls.
By executing the animation "Flight View", you can see the improved western highway while flying all the way. In "Driver View", you can see the image of the road structure and landscape from the driver's viewpoint by driving in a typical section. In addition, by executing "Plan", you can check the contents of the discussions, comparison of images before and after improvement, driving image, etc.

"A complex facility like a plaza where everyone gathers Sakakiminato Civic Center (provisional name)" Sakaiminato City
New construction of Sakakiminato Civic Center (provisional name) is underway. It's a complex facility with a hall, a library community plaza, and a conference room with an art exhibition function, etc. The front entrance of the building has the image of a gentle curve on the Yumigahama Peninsula. It is a multifunctional facility equipped with a place for citizens to interact, a base for interaction with the Self-Defense Forces, and a evacuation shelter in the event of a disaster where the hall becomes flat, and we created a VR content to promote it with the sence of presence of the building.
By executing the animation "施設概要", you can see the image of the area such as the location of the facility and the positional relationship with Mizuki Shigeru Road, and the inside of the facility is also expressed in a digest. In addition, if you select "施設ウォークスルー", you can see the inside of the facility in order from the entrance to the hall, and you can experience and enjoy the atmosphere of the facility from the viewpoint of an actual person.

"Examination of effective construction plans in road improvement projects" Mitsui Consultants Co., Ltd.
Introducing test cases using VR technology, which is a part of CIM/BIM, for smooth consensus building with local residents, related national road managers, city road managers, etc. in road improvement projects carried out by the prefecture. As an effect of introducing this technology, many meetings and periods related to coordination have been significantly decreased by half. In the future, smooth business promotion is expected by further utilization of VR.
If you run the animation "道路改良事業における効果的な施工計画検討", you can check the flow of road improvement work in 10 stages. The procedure of road construction and the image of vehicle traffic during construction are expressed in an easy-to-understand manner. You can also check the scenery before and after the construction of the pedestrian bridge, the traffic image and the planned construction of a retaining wall.
Traffic simulation Award

"Traffic restriction simulation due to intersection construction in Sapporo" IWATA CHIZAKI Inc.
A traffic simulation was executed to check the affects of traffic restrictions due to construction. Before setting up the restriction zone at the construction site which was near an intersection and at the center of carriageway, the traffic jam at peak times, the congestion of vehicles turning right, and the visibility from drivers were simulated to test the validity of the restrictions. The result was used for the proposal to the clients and users.
When you run the animation "交通シミュレーション", you can see the structure of intersections, the traffic situation, and the traffic simulation comparing normal time and during the planned construction. In addition, by running through the scenario, you can check what a driver's view will look like when waiting behind a vehicle waiting for a right turn.
"Smart IC and VR driving simulation" Chuo Sekkei Inc.
This VR simulation was created to be open on the company's website. The data using UC-win/Road and 3D software includes slopes, box culverts, and roundabouts that can be used in discussions on the outline design. It reproduced a bird view to look down the overall view, and a vehicle without ETC going around the roundabout and returning to the main road.
In this work, the highway main line, the roundabout of the upper and lower lines, and the smart IC are expressed, and you can experience various simulations by executing the scenario "ランプUターン". You can check the overall view, the roundabout, and the viewpoint of the vehicle without ETC that goes around the roundabout from the smart IC and returns to the main line from a bird's-eye view. On both roundabout central islands, aprons and symbol trees are installed with colored pavement, and the contents are designed with consideration for safety and landscape.

This is a design example of a highway under construction in the mountains of southeastern China. "Gradient design of slope" and "Tunnel design" are depicted in VR, and daylight environment and lighting at night are reproduced in both designs. Driving simulation tests were conducted by also using the real lighting.
If you execute the scenario "シミュレーション評価実験", you can see the representation of the simulator used for the evaluation and the explanation of the experiment method. In addition, by executing the scenario in 8 patterns, you can run the course to be used in the experiment and check the image of the comparison pattern.
