Collision Detection in the Analytics Lab

The collision detection experiment in the Geotab Analytics Lab reviews and confirms collisions that are automatically detected by the telematics GO device. Users can also use this tool to report collisions manually. Here is a link to “How to download and install Analytics Lab” in your Geotab database. After installing Analytics Lab, go to the Collision detection experiment and click try it.

Collision Detection – the Technical Stuff

Collisions are detected by the Geotab GO device upon any acceleration greater that or equal to 2.5 G, where G is 9.81 m/s2 (the acceleration due to the Earths gravity). This is classified as a collision-level event. Geotab GO device firmware will not use/Up/Down accelerometer data (also known as the Z axis) in this calculation. The calculation uses the magnitude of the hypotenuse between X and Y where X is Forward/Braking and Y is Side to Side.

When the GO device detects a 2.5 G event in any direction, the device is triggered to start recording at 100 Hz frequency. This detailed, high-resolution information will be reflected in the trip in MyGeotab, and includes acceleration, GPS speed, and brake data (if available).

About the Experiment

The Data Analytics Research team, using advanced analytics techniques, has developed a model capable of detecting collisions when they happen to present critical information on point of impact, magnitude to help users monitor, act, and take measures to mitigate future collisions.

How Does the Collision Detection Experiment Work?

Because it can provide an accurate scientific record of events, telematics data proves to be highly valuable for Fleet management. The model monitors the telematics data and applies what it has learned as signals in accelerometer data to detect and classify collision events. Due to the granularity of the data, the model can tell you many things about a collision such as a point of impact, trigger type, location, time, and much more. With this experiment, users could gain a broader perspective on the event by looking at the historical patterns for a specific driver or vehicle.

What is the Benefit to Fleets?

  • Fast and easy to use method to detect potential collisions.
  • Provides critical data to take Collision workflow decisions and actions.
  • Point of impact can provide a better understanding of the overall accident as it occurred.
  • Increasing overall fleet safety by unlocking patterns in-vehicle, locations, and conditions to reduce potential collision in the future.

Weather Impacts Profitability

When Time Counts

When the weather turns bad, consider how frequently you check the weather radar. You recognize the importance of good weather radar and data in your personal life, but do you apply the same to your fleet management practices? Weather radar provides information on more than just rain and snow. There are weather services that can predict black ice, surface temperatures and even tornado several hours into the future. The impact of good weather radar for drivers and dispatchers cannot be overestimated.

National Dispatching

When a team of people in a New York call center are dispatching trucks across the country, they must understand the weather factors in areas they are unfamiliar with. When there is 5′ of snow on the ground it is foolish to attempt a delivery to some areas. When dispatchers are able to see areas of heavy snow or probable black ice, they can route vehicles around hazardous weather and produce more revenue than otherwise possible. Drivers arrive alive. Trucks are not stuck or involved in accidents and customers expectations are managed and met more consistently.

 

Predictive Logistics

Wouldn’t it be great to know what is going to be needed before you received the order so you can offer just in time delivery of inventory? Everyone is familiar with the challenge of having the right inventory on hand to meet spikes in demand. Understanding where short-term demand will take place and how to get the supplies to meet the demand, can result in significant revenue increases. Of course you have the option to continue to do business the old way and respond two weeks after the demand has passed.

With almost everything in this country moving by truck at some point, knowing how weather impacts supply on short-term demands is critical. In many industries weather impacts demand in addition to supply. If a cold snap means the corns gets picked early, having trucks available to transport the corn is vital. If more tires are needed when the temperature exceeds 110 degrees in Arizona, having a 2 day heads up to move inventory can mean a spike in revenue. Being HOS compliant means not getting stuck in a hotel for 12 hours.

 

Weather Radar Integrated with GPS Tracking

With over 17 years of experience working with fleets, Fleetistics recognizes the need for fleet operators to see the location of their vehicles on same map during major weather events. Fleetistics customers utilizing Geotab telematics devices can choose from a variety of weather map layers depending on their location and transportation needs. Companies providing roadside assistance, to truckers, can deploy their technicians in a safer manner or change the schedule based on weather conditions to keep employees safe and customers serviced.
