Among its various research programmes, V2X (Vehicle to Vehicle and Vehicle to Infrastructure) Communications is one of the key research focuses at INFINITUS. The primary objective of this research is to advance the technologies and capabilities in intelligent transportation systems (ITS), and to transform the NTU campus into a V2X technologies hub which can provide open platform for worldwide ITS-related communities, industries, and research organizations for their research and development activities.
Our Professors, Scientists, Research Staff, Engineers and Research Students have active partnerships with public, private and academic sectors in developing such V2X technology hub into reality. The main research activities in this test-bed project are to:
- develop and set up a live and permanent campus-wide V2X test-bed over the whole NTU campus, and
- develop and demonstrate prototypes for dedicated short range communication (DSRC) technologies and protocols, network security, data analytics, RF design, traffic management, application development, and test and measurement frameworks.
This project is fully supported and funded by government and local and international industry including electronics manufacturing industry, car making industry and IT industry.
INFINITUS provides a number of lab equipment and facilities for developing and test-bedding DSRC technologies which is used for V2X communications. We have showcased our experimental works on DSRC technologies, which include:
- real-time video streaming over DSRC 802.11p network using vehicles driving along NTU campus, PIE highway, and residential areas with high-rise building,
- real-time mapping GPS information of neighboring cars on a map so as to provide driver situational awareness and alert potential hazards, and
- studying DSRC 802.11p link behavior under the line-of-sight and non-line-of-sight environmental conditions.
Photo of our recent V2X Communications drive tests using 5.9 GHz DSRC 802.11p can be seen as below.
For real-time video transmission drive test, three vehicles are used, where the front car is transmitting the video of its front view, which is then relayed by second car to the destination car. The screenshots of this drive test on PIE highway and at NTU junction can be seen in the photo. Two vehicles are used for GPS mapping and communication link quality study experiments. We conducted this drive test along the residential area with high-rise buildings and its screenshot can be seen in the bottom left of the photo.
