Movon MOIS ( Moving Off Information System ) warns a driver of the presence of pedestrians and cyclists at the critical blind spot area in front of a vehicle at 0~10kmh. 79GHz RADAR sensors make use of millimeter wave to detect and calculate the distance between the car and VRUs in front of the truck. RADAR senso would be placed on the front hood of the truck to ensure that the millimeter wave can travel uninterrupted. This MOIS alerts the driver by visual and audio alarming; as the car moves closer to VRU ( Vulnerable Road Users ) in front blind spot zone, the beeping sound could be generated to inform a driver of the impending collision danger. ECE R159 : this Regulation requires the activation of a proximity information signal in case pedestrians or cyclists enter the critical blind spot area in front of the vehicle, should the subject vehicle either be preparing to move off from rest in a straight line or be travelling straight ahead at low-speeds.

We develop 4D-dataset-based radar signal processing algorithm in order to detect and track Pedestrians and Bicycles at the critical blind spot area in front of truck. 4D dataset consists of Distance, Azimuth angle, Elevation(Height) and Relative Speed data. 4D radar uses a large Multiple Input Multiple Output (MIMO) antenna array for echolocation. It sends signals that bounce off objects in the environment and captures the results to calculate the size, location, direction, speed, and elevation of objects in the environment. 4D radar has the advantage of being able to work in any weather and any level of lighting, detect elevation, speed, and direction accurately, and detect targets behind other objects in the environment.

Movon BSIS system uses 79GHz Short Range RADAR ( SRR ) to detect VRUs and vehicles on the side of the vehicle and warns a driver at the impending collision risk. In accordance with EU R151 regulations, RADAR units are attached to the left and right sides of the vehicle to detect VRU within total 40 meters from about 20meters behind the vehicle to about 10 meters ahead of the front bumper. If there is a collision risk, the indicator attached to the A-pillar is showing a visual alarm and a voice warning is issued through a speaker installed in the vehicle. BSISI warning is generated at the lower driving speed or standstill in an urban road environment where there are many bicycles and pedestrians. When the speed exceeds 30Km, the Lane Change Assist function is activated, and when there is a vehicle in the next lane when changing lanes, the driver is notified visually and audibly to assist in changing lanes safely.

Movon BSIS is the RADAR-sensor-based system installed on a truck/bus to inform the driver of a possible collision with a bicycle near side, it is obvious to use such assistance system for avoiding accidents between turning trucks and cyclists on the upcoming crossroads. BSIS calculates a dynamic estimate of collision danger like time-to-collision algorithm and warns the driver that immediate attention is required in order to avoid colliding with the detected obstacles of VRU ( Pedestrians, Cyclists, Motorcycle, e-Bike and e-Scooter ). 79GHz mm wave RADAR is a type of millimeter-wave radar that is used in automotive applications. The 79GHz millimeter wave radar is suitable for detecting cars, motorcycles and cyclists. It has high resolution and robustness at nighttime and in bad weather. The conventional 77 GHz-band millimeter-wave radar operated in the bandwidth of 0.5 GHz, whereas the 79 GHz band high-resolution millimeter-wave radar has 4 GHz, an eight-fold increase. Thus, we estimated the resolution could be improved in the range from 1.5 m to 0.18 m. The 79GHz millimeter wave radar is suitable for detecting cars, motorcycles and cyclists. Millimeter wave (mmWave) is a special class of radar technology that uses short-wavelength electromagnetic waves. Radar systems transmit electromagnetic wave signals that objects in their path then reflect. By capturing the reflected signal, a radar system can determine the range, velocity and angle of the vehicles. MmWave radar transmits pulses of mm electromagnetic wave energy and detects targets from the reflections it receives back. Multiple antennas in mmWave radar capture reflected signals. By processing the time of flight of these mmWave pulses, the distance to the target, angle of arrival, and relative velocity are determined. Movon BSIS uses a 3.5-inch LCD indicator as an warning device. So, it can be clearly seen by a driver even if it is installed 2 meters away from the driver. Since it is a speaker-integrated type to support voice alarm. Because of the innovative cradle design, it can be mounted on the dash-board in front of the driver's seat and near by A-pillars. When an object is recognized and detected, the location of the object can be indicated in three steps on 3.5inch LCD alarming device. It can be displayed within 10 meters ahead the vehicle, side of the vehicle, and within 20 meters behind the vehicle. Since it uses wide LCD screen, various icons suitable for alarm situations can be implemented. It communicates with BSIS's ECU Box through CAN. The following voice alarm sentences are generated according to event types.

Increased use of public bicycles and escooters

Driving on and off roads and sidewalks

91 deaths last year... 30% surge ( source : https://www.hankyung.com/society/article/2023061996321 )

Frequent 'side collision' accidents with cars

Be careful when entering the alley → road

On the afternoon of the 19th, at the Yeouido Transfer Center in Yeouido-dong, Seoul. Several taxis were waiting for customers occupying the 1.5m-wide bicycle road paved with red urethane. An office worker who rode the Seoul public bicycle “Ttareungi” without a helmet ran acrobaticly to avoid illegally parked taxis. Another cyclist went up to the sidewalk and then went back to the traffic island and almost collided with a passing car. Mr. Seo (31), an office worker, said, "Urban cyclists are inevitably at risk of accidents while traveling between sidewalks, roads, and traffic islands."

With the number of bicycle users nationwide exceeding 13 million, the damage caused by bicycle traffic accidents is rapidly increasing. In addition to the existing bicycles, new means of transportation such as electric bicycles and kickboards have emerged, resulting in a 30% increase in the number of deaths due to bicycle accidents compared to the previous year.

30% increase of bicycle fatalities

According to the National Police Agency on the same day, the number of deaths in bicycle accidents last year was 91, the highest since 2017. This is a 30% increase from the previous year (70 people). Police believe the actual death toll may be more than 100. This is because many cases are handled without being reported to the police.

As of this year, 18 people have died as of April. On the 16th, Joo Joong-joong, a professor of cardiovascular and thoracic surgery at Asan Medical Center in Seoul, who is called “aortic surgeon”, died in a traffic accident while riding a bicycle. It is known that the truck driver who was turning right did not see Professor Joo, who was crossing the crosswalk near the traffic island on his bicycle.

Many of the bicycle deaths are collisions between cars and bicycles, as in Professor Zhu's case. According to the National Statistics Portal’s ‘Status of Bicycle Traffic Accidents by Accident Type’, out of 5509 bicycle-related accidents that occurred in 2021, collisions between cars and bicycles accounted for an overwhelming proportion of 3992 cases (72.6%). That's an average of 10 or more cases per day. Among them, side collisions were the most common with 1944 cases. This is a type of accident in which a bicycle enters the road from an alley or collides with a vehicle coming from a crosswalk. There were also 26 deaths.

Accidents involving scooters and electric bicycles are also serious.

Although the means of transportation that did not exist are evolving rapidly, there are many cases where civic consciousness or legal systems cannot keep up. An example is an electric bicycle equipped with an electric motor on a bicycle. The police explained that the degree of injury in the event of an accident is serious because it can run up to 25 km per hour. However, only a portion of e-bikes are counted as bicycle accidents. Even for electric bicycles, throttle-type bicycles that operate the motor by turning the lever with your hands without stepping on the pedals are classified as personal mobility devices (PM) and are subject to the Road Traffic Act. This means that it is missing from the bicycle accident statistics. On the other hand, PAS (Pedal-Assisted) type electric bicycles, whose motor operates only when the pedals are turned, are subject to the Bicycle Act.

Accidents with shared kickboards, which are frequently used by teenagers, are also on the rise. According to data from the National Police Agency, there were 2,386 scooter accidents last year, with 26 deaths. In particular, the number of accidents involving personal mobility devices for teenagers under the age of 19 recorded 1,096 last year. It increased by about 44 times the 25 cases in 2018. Police attribute more than 90% of accidents to kickboard accidents.

Experts advised that safety measures should be put in place for cyclists who are not welcome on both roads and sidewalks. Lee Jae-young, a senior researcher at the Daejeon Sejong Institute (executive director of the Korea Bicycle Policy Association), said, “In addition to the expansion of bicycle-only roads, a separate transportation policy for bicycles is needed.” It is also urgent,” he pointed out.
