Gps And Blind Spot Monitoring: Safety Features Explored

There are a variety of GPS devices and GPS-adjacent technologies available on the market that can help with blind spots and pedestrian monitoring.

For blind spot monitoring, there are several options available on Amazon, including car blind spot cameras, displays, recorders, and monitoring systems. These systems typically use sensors to detect obstacles in a vehicle's blind spot, providing either visual or audio alerts to the driver.

As for pedestrian monitoring, there are a number of GPS trackers and navigation devices that can be used to track the movement of pedestrians, especially in urban areas. These devices often use smartphone GPS data to collect information about pedestrian behaviour, including location, movement, and speed. This data can then be used to improve safety, develop urban planning, and monitor health and well-being.

Overall, there are a range of options available for those seeking to improve safety and visibility on the roads and in urban spaces.

Ultrasonic blind spot detection systems

Ultrasonic blind-spot detection systems are an effective way to increase safety on the road. These systems use ultrasonic technology to detect objects in a driver's blind spot, including small obstacles from 4-10m away and larger obstacles from 15m away. Ultrasonic sensors are typically embedded in each side of a vehicle's rear bumper, and some systems also employ side-mounted cameras.

When an object enters the driver's blind spot, ultrasonic blind-spot detection systems typically alert the driver through a combination of visual and audio cues. Visual alerts may include a blinking LED indicator light on the side mirror or the pillar between the windshield and front door. Audio alerts may include a beeping noise, which can be deactivated in some systems.

Ultrasonic blind-spot detection systems are available as both factory-installed and aftermarket options. Factory-installed systems tend to be more common as the sensors are seamlessly integrated into the vehicle's design and covered by the manufacturer's warranty. Aftermarket kits can be purchased for older vehicles, typically ranging in price from $300 to $500, with professional installation costing at least an additional $200.

It is important to note that ultrasonic blind-spot detection systems have some limitations. They may only function at certain speeds, and not all systems are capable of detecting pedestrians, cyclists, or pets. Additionally, it is the driver's responsibility to properly aim their mirrors and visually check their surroundings before changing lanes or merging.

Overall, ultrasonic blind-spot detection systems offer increased safety and peace of mind while driving. They provide drivers with early warnings and increased reaction time, helping to prevent accidents and minimize the severity of potential collisions.

GPS-assisted indoor pedestrian dead reckoning

A 2023 study by Heng Zhou and Takuya Maekawa proposes a machine-learning-based module for detecting when a user is near a window and the window's orientation, which can then be used to determine the smartphone's absolute coordinates and correct PDR errors. This method does not require additional device installations or training data collection in the target environment.

Another 2023 study by researchers at Shenzhen Polytechnic and Huazhong University of Science and Technology proposes a radar-assisted PDR scheme called RadarPDR, which integrates a frequency-modulation continuous-wave (FMCW) radar with inertial sensor-based PDR. RadarPDR uses a segmented wall distance calibration model to address ranging noise caused by irregular indoor building layouts and fuses wall distance estimation with acceleration and azimuth signals measured by smartphone inertial sensors. It also uses a hierarchical particle filter and an extended Kalman filter for position and trajectory adjustment.

Inertial navigation systems (INS) that use dead reckoning are widely applied and provide very accurate directional information. Dead reckoning is also used in vehicular navigation, robotics, and gaming and simulation tools. In the automotive industry, dead reckoning is implemented in some high-end navigation systems to overcome the limitations of GPS technology alone.

GPS trackers for vehicles, kids, dogs, motorcycles, etc

GPS trackers can be used for a variety of purposes, such as tracking vehicles, kids, dogs, and motorcycles. Here is some detailed information about each of these applications:

GPS Trackers for Vehicles

GPS trackers for vehicles can be used for a variety of reasons, such as tracking a company's fleet of vehicles, monitoring a loved one's vehicle, or locating a stolen car. These trackers are usually small devices that can be installed directly on the car's battery or plugged into the OBD port. They provide real-time location information and some even offer additional features such as dashcam video recording.

GPS Trackers for Kids

GPS trackers for kids are often used by parents to ensure their children's safety and keep track of their whereabouts. These trackers can be standalone devices or integrated into smartwatches. They offer features such as real-time location tracking, geofencing, and two-way communication. Some trackers also include panic buttons and sensory-sensitive designs for kids with special needs. It's important to consider factors such as durability, battery life, and ease of use when choosing a GPS tracker for kids.

GPS Trackers for Dogs

Pet GPS trackers are designed to help pet owners locate their furry friends in case they go missing. These trackers can be attached to a dog's collar or existing collar, providing location and activity tracking. Some trackers offer additional features such as health monitoring, sleep tracking, and calorie tracking. It's important to choose a tracker that is comfortable and secure for your pet, with long battery life and accurate location updates.

GPS Trackers for Motorcycles

Motorcycle GPS trackers are useful for preventing theft and locating stolen bikes. These trackers are small and can be hidden in various places on the motorcycle, such as under the seat or near the airbox. They provide real-time location tracking and can send alerts to your phone if unauthorized movement is detected. Some trackers also offer additional features such as silent alarms and battery life notifications.

Backup camera systems

When choosing a backup camera system, it is important to consider the camera's mount location, which can include the license plate, tailgate, bumper, or spare tire. Additionally, features such as wide-angle lenses, low-light capabilities, and night vision can enhance the system's performance and provide a clearer view of the surroundings.

There are a variety of backup camera systems available on the market, offering different features and price points. For example, the iBEAM License Plate Back-Up Camera offers night vision and active parking lines, while the AUTO-VOX Solar Wireless Backup Camera provides a 5" HD monitor and battery-powered installation.

In recent years, backup cameras have become standard features in new vehicles, with automakers recognising their importance in enhancing safety and reducing insurance premiums. However, for older vehicles, aftermarket backup camera kits are also available, offering a cost-effective solution for those seeking to improve their driving visibility and safety.

Smartphone-GPS data to understand pedestrian-scale behaviour

The near-ubiquitous presence of smartphones has turned the public into continuous sensors of urban spaces. Smartphone-GPS data can be used to understand human spatial behaviours in cities, and their potential for societal monitoring has been highly anticipated.

A review of 96 research papers using GPS data from smartphones to understand pedestrian-scale human behaviours revealed seven application themes:

• Sports and physical activity
• Environmental conditions
• Health and well-being
• Places and movement
• Neighbourhoods and society
• Tourism
• Single amenity use

The analysis of pedestrian GPS datasets is fundamental to the study and design of walkable cities. Purpose-based recurrent mobility data inside people's neighbourhoods is an important source for these studies. However, micro-mobility around people's homes is generally unavailable, often due to privacy issues. Citizen science and its public involvement practices in scientific research are valid options to circumvent these challenges and provide meaningful datasets for walkable cities.

In a citizen science initiative called Beepath, researchers collected GPS data from 427 participants (students aged 14-16) in the Barcelona metropolitan area. The participants used a mobile app to track their home-to-school or school-to-home trajectories. The data was then processed and analysed to understand pedestrian mobility patterns and make recommendations for improving walkability in the city.

Smartphone-GPS data has a broad range of applications and is particularly useful for understanding human behaviours in urban settings. By collecting and analysing data from a large number of participants, researchers can gain insights into pedestrian-scale behaviours and make informed recommendations for urban planning and design.
