[M-Tech와 함께 안전운전] 〈6〉 Car-to-object communication V2X warning system
Smartphone sensor-state-of-the-art CCTV linkage… Street scenario evaluation and real-time warning with AI
Pedestrians are additionally notified to beware of auto collisions.
U.S. “Saves as much as 1,300 lives per yr”
“Watch out when approaching pedestrians.”
On the afternoon of the twenty third of final month, a warning message appeared on the cell phone of a reporter who was driving close to the kids’s safety space (college zone) of Naseong Elementary Faculty in Sejong Metropolis. In reality, pedestrians have been crossing the crosswalk in entrance of the elementary college’s major gate. It notifies the chance of collision by combining the placement and movement sensors mounted on the smartphone with the highway circumstances detected by synthetic intelligence (AI)-based good closed-circuit (CC)TV put in on the highway. When a motorbike got here shortly from the opposite aspect of the intersection, a notification warning of the chance of collision additionally appeared.
This warning system, which makes use of mobile-based vehicle-to-object communication (V2X) expertise, was extra helpful in alleys the place there have been no visitors lights or many blind spots. On the slender highway surrounding Naseong Elementary Faculty, when pedestrians rushed out onto the highway to cross a crosswalk with out a visitors gentle, a warning discover appeared with out fail. There was an expectation that it will be particularly useful on roads at night time or within the rain the place it’s tough to see pedestrians with the bare eye.
●CCTV-mobile telephone linkage to warn of ‘collision danger’
With the intention to forestall surprising accidents, the variety of automobiles outfitted with collision avoidance methods to shortly determine dangers that can’t be detected by human eyes and ears is rising. Nevertheless, the sensors on the automobile are ineffective if they’re out of the bodily recognition vary, resembling being crushed by obstacles, and that is the place V2X expertise is predicted to be useful like Somers (a superwoman in American dramas with developed listening to). It is because synthetic intelligence (AI) can be utilized to research not solely automobile sensors but additionally data obtained from pedestrians and drivers’ cellphones and CCTV, in order that even remotely distant accident dangers will be predicted in actual time.
In reality, when the reporter put in LG Electronics’ cellular software (app) ‘Site visitors Security Alert’ utilizing V2X expertise and drove round Sejong Metropolis, when youngsters bought on and off the kids’s college bus, they mentioned ‘Getting on and off the college bus’. I used to be in a position to precisely perceive the highway circumstances, together with displaying an Iranian notification. The app additionally calculated and displayed what number of seconds have been left till the visitors gentle modified to inexperienced.
Not solely drivers, but additionally pedestrians and cyclists might obtain the identical notifications. After I put in the app and was about to cross the crosswalk, a automobile modified path on the nook and headed towards pedestrians, and the ‘automobile collision warning’ alert sounded. As well as, when a pedestrian jaywalks, a notification saying “jaywalking is harmful” and a vibration sound are sounded to boost consciousness.
●“7 out of 10 customers responded instantly”
Beforehand, a devoted gadget was required to make use of V2X, however this app works with only a smartphone. Place and movement sensors such because the inertial measurement unit (IMU) or world positioning system (GPS) mounted on the smartphone detect the person’s location, path and pace, after which use this to It is because it’s transmitted from the cloud server to different drivers and pedestrians by way of communication networks resembling ). To stop any considerations about private data being leaked, all collected data is anonymized and delivered.
As well as, by linking with the ‘Subsequent Era Clever Transportation System (C-ITS)’ that the federal government and native governments are at present constructing in earnest, you may even obtain highway circumstances extracted from good CCTVs put in at intersections. Even the actions of distant automobiles or pedestrians will be monitored remotely.
Within the precise demonstration undertaking, most individuals who obtained warning/warning notifications by way of the app have been in a position to answer the chance of accidents by instantly lowering their pace. Because of an empirical undertaking carried out in three college zones in Gangseo-gu, Seoul from December 2022 to June of final yr, customers responded to 9,547 (73.2%) of a complete of 13,051 notifications. 69% of pedestrians and 88% of drivers slowed down, and 31% of pedestrians modified the path they have been strolling. An analogous impact was seen in Seongsan-myeon, Gangneung-si, Gangwon-do, the place about one-third of the inhabitants is over 65 years outdated, in an indication undertaking carried out between March and Could of this yr. Final month, a research confirmed that jaywalking could possibly be decreased by 93% simply by displaying sign change instances and jaywalking warnings.
●Effectiveness is bigger when linked with authorities and native authorities infrastructure
Due to this impact, in some international locations the federal government helps the unfold of V2X. In 2016, the U.S. Division of Transportation introduced the outcomes of a research that mentioned, “Utilizing solely a portion of V2X expertise can forestall roughly 440,000 to 620,000 collisions and save 987 to 1,366 lives yearly.” Accordingly, the U.S. Division of Transportation introduced in October final yr that it will present $40 million (about 55.3 billion received) in subsidies to develop V2X expertise.
For V2X expertise to be extensively used, cooperation between the federal government and native governments is crucial. With the intention to obtain smartphone GPS and inertial sensor data from different pedestrians or drivers, that particular person should even have the app put in. In any other case, the federal government and native governments should detect their motion data solely by way of AI CCTV put in on the highway. Final month, 14 native governments, together with Anyang-si, Gyeonggi-do, and Suwon-si, along with KT, started pilot operations of the self-driving bus ‘Day and Evening’, which mixes V2X and C-ITS applied sciences.
Kim Hak-seong, a researcher at LG Electronics who’s in control of creating the visitors security alert app, mentioned, “Cell-based V2X expertise is predicted to have an important impact on roads the place accidents are decided in a brief time frame as a result of it gives real-time data that occurred inside 0.05 seconds on common.” mentioned.
