As a product of high integration of informationization, industrialization and intelligence, the “smart transportation†system brings diversified value, including the sharing of resources brought by Didi, sharing bicycles, etc., as well as Didi as an intelligent travel platform for drivers and The precise geolocation technology provided by both passengers, the ability of rapid response system, the self-discipline mechanism built by credit and other constraints, and the low-cost operation driven by big data make the intelligent travel platform itself and millions of transportation service providers nationwide. And hundreds of millions of passengers have benefited. Building smart transportation requires the support of a variety of innovative technologies. So, what are the exciting applications of the hot VR technology in the field of intelligent transportation?

1, VR technology is used to test traffic plans
The UK's Kadap Transportation System has demonstrated a new “visualization laboratory†that uses the power of VR to help solve traffic problems and save money on related tests.
It is called the “Visual Lab†because it consists of a large 20-foot omnidirectional treadmill and an Oculus Rift DK2. The Kadap Transportation System hopes to rely on this complete VR system to bring innovative and practical solutions to the problems of the current UK transportation system.
The huge omnidirectional treadmill, called Omnideck6, allows users to walk, run and even move forward. With the Oculus virtual reality display, researchers can test new transportation solutions and buildings in virtual towns. Many people participate in R&D testing, saving valuable trial time and money.
2. Application of VR technology in traffic safety publicity and education
Traffic safety publicity and education is of great significance at present, but the current traffic safety education basically adopts inefficient irrigation education. The main reason is the lack of effective educational methods, means and education platforms.
Using the virtual reality (VR) technology to create a virtual traffic experience scenario and a traffic safety education and training system built by human-computer interaction, not only can the majority of traffic participants be immersed in the virtual traffic environment to experience various Traffic behavior to learn traffic safety knowledge, but also through various training in a realistic virtual traffic environment to improve various traffic safety skills, such as to achieve drunk driving traffic accident simulation experience.
There is also a kind of psychological guidance means - panoramic virtual reality VR traffic life safety experience sand table, is also a practical panoramic life traffic safety exhibition show sand table. It is a real-life interpretation of the light sand table + virtual venues integrated in an area, for the majority of customers to intuitively solve the traffic safety multimedia means.
The traffic safety sand table has a good effect on public transportation safety education. In the panoramic virtual reality VR traffic life safety experience museum, the security propagandists use the cartoon image to make simple and understandable traffic rules to the public, and at the same time simulate the real traffic environment on the spot so that children can learn through the learning process. Traffic safety knowledge such as "walking the crosswalk" "How to identify the signal light" and "crossing the road danger".
3. VR technology is used in rail transit simulation system
Rail transit simulation is to use three-dimensional virtual and simulation technology to simulate the three-dimensional environment from the design and manufacture of the rail vehicle to the operation and maintenance, and the three-dimensional environment of each link. In this environment, the user can “full-heartedly†invest in the whole project of rail transit. Various operations are carried out to expand the cognitive and cognitive fields of relevant practitioners, saving costs and time for the entire project of rail transit construction, and improving efficiency and quality.
The main application areas of VR technology here include three parts:
First, virtual design.
Virtual design includes track design, rail vehicle design and rail transit environment design. Virtual reality technology is not directly involved in design in rail transit design, but as an efficient auxiliary tool for designers to help designers save design time and improve the quality of design products.
Second, virtual assembly.
In order to ensure that the design of the rail vehicle meets the requirements of various disciplines such as fluid mechanics and engineering mechanics, the virtual assembly of each component is realized by computer technology, and the fitting degree and compatibility between the various components are conveniently checked; in addition, the virtual assembly is also It can be further developed into an interactive 3D virtual training environment, allowing trainees to familiarize themselves with the various components and assembly processes in an immersive environment and improve the equipment assembly capabilities of the trainees.
Third, virtual operation.
Before the train is put into use, the three-dimensional virtual simulation technology is used to simulate the state of the train during operation, the change of each component and the surrounding environment, and check the feasibility of the train operation. It is also possible to use the computer to change part of the data and observe that the train is affected by the data change. The linkage effect will sum up more train operation experience, effectively avoid the risks after the train is officially put into use, and improve the ability of relevant staff to deal with unexpected situations.
4. Application of VR technology in the field of driving training
On October 9, 2016, a new application of VR technology, VR virtual driving technology, appeared at the World Simulation Technology Application Exhibition.
The technology is currently used in the field of driving training. Applying VR cutting-edge technology to driving simulators not only realizes the standardization of driving training, but also ensures the driving and training level, and also develops simulated road driving. By simulating the actual road conditions, students can apply theoretical knowledge to the actual situation immediately. Going in the road scene, avoiding the embarrassing situation of not taking the driver's license and not being able to get on the road and driving on the road.
5, VR technology is applied to in-station navigation
In view of the unfamiliarity of some passengers on the structure of the railway station, during the Spring Festival of 2017, Nanchang Railway Bureau launched VR (virtual) panoramic navigation at key stations in Nanchang West Station, Fuzhou Station and Xiamen Station. Hubei Hankou and Wuhan Railway Station also provide 360-degree panoramic navigation function in VR station for the first time on Weibo and WeChat.
Entering the “Nanchang Railway†WeChat platform, passengers can use the smart phone before the ride to experience the virtual experience of pit stop, security check and waiting in advance, and also support VR device viewing. Passengers can intuitively grasp the specific location of each key point in the station. .
In the passageway of the Hankou Railway Station station, a 60-inch VR display is set up. Through the VR display, passengers can more intuitively see the ticket office, the entrance station, the waiting room, and the lost and found office, key passengers. In the waiting room and other places, the station will take less "detours".
6. Application of VR technology in roads and bridges
Virtual reality technology has also been applied in the construction of highways and bridges.
Because road bridges need to process a large number of 3D models and texture data at the same time, this situation requires high computer performance as background support, but with the improvement of computer hardware and software technology in recent years, some original technical bottlenecks have been solved. To make the application of virtual reality reach an unprecedented development.
Virtual reality technology has a very broad application prospect in highway and bridge construction. Stable database information can be placed in the background, so that the audience can conduct real-time query on various technical indicators, and the surrounding area is supplemented with various media information, such as engineering background introduction, bidding overview, technical data, cross section, etc., electronic map, sound, Image, animation, and interaction with the core virtual technology to achieve a variety of practical and convenient functions such as navigation, positioning and background information in the presentation scene.
