Introduction

Using advanced analytics techniques, the Data and Analytics Research team has developed a model capable of detecting collisions when they happen to present critical information on point of impact and magnitude. This allows you to monitor, act, and take measures to mitigate future collisions.

The Enhanced Accelerometer Experiment Add-In uses an improved accelerometer threshold to detect potential collisions, and captures feedback from users to achieve enhanced accuracy and precision in collision detection.

The Enhanced Accelerometer Experiment page includes the following features:

1. Search for recorded acceleration events — Narrow down the list of collision detection events. Refer to Finding recorded acceleration events for more information.
2. List of recorded acceleration events — Provides a quick overview of vehicles, date and time of event, and impact for the associated event.
3. Provide feedback — Flexibility of providing one-click feedback, and/or adding more information to a report for which you have previously submitted feedback.

Getting Started

Accessing the Enhanced Accelerometer Experiment Add-In

To access the Enhanced Accelerometer Experiment Add-In, follow these steps:

1. Navigate to Dashboard & Analytics > Analytics Lab from the MyGeotab main menu.
2. Find Enhanced Accelerometer Experiment, then select Launch experiment.

The Enhanced Accelerometer Experiment page is displayed.

You can now access the Enhanced Accelerometer Experiment Add-In via Dashboards & Analytics > Enhanced Accelerometer Experiment.

Recorded Acceleration Events

The Enhanced Accelerometer Experiment Add-In is designed to detect when a vehicle’s accelerometer reaches a magnitude of 1.5g and over. When this is detected, an event is recorded for your review.

Finding recorded acceleration events

You can use filters to narrow down the list of recorded acceleration events.

To narrow down the list of recorded acceleration events, follow these steps.

1. Navigate to Dashboards & Analytics > Enhanced Accelerometer Experiment.
2. Use the following filters to narrow down the list of recorded acceleration events:

✱ NOTE: Select More to open filters if it’s not displayed.

3. 1. Date range — Select a date range. You can also select the days of the week.

   ✱ NOTE: Select View all events to view a list of all potential collisions.

   2. Search — Enter or select a vehicle name, VIN, or group.

The list of recorded acceleration events updates based on your filter selections.

✱ NOTE: You can use Sort to sort the list by Name, and Date.

Enhanced Accelerometer Experiment overview

By default, the Enhanced Accelerometer Experiment page displays a list of all detected collisions.

The following information is displayed on the Action Needed and Reviewed tabs.

Action Needed

By default, the Action Needed tab displays vehicles that have met the accelerometer threshold to be a potential collision, and require your feedback. A number is also displayed next to Action Needed to show you how many recorded acceleration events require your feedback.

To find detected collisions within a specific time period, refer to Finding recorded acceleration events.

To provide feedback for recorded acceleration, follow these steps:

1. Navigate to Dashboards & Analytics > Enhanced Accelerometer Experiment.
2. Select the Reviewed tab.

A list of recorded acceleration events you previously provided feedback on is displayed.

3. Use the following filters to narrow down the list of recorded acceleration events:

✱ NOTE: Select More to open filters if it’s not displayed.

4. 1. Date range — Select a date range. You can also select the days of the week.
   2. Search — Enter or select a vehicle name, VIN, or group.

   The list of recorded acceleration events updates based on your filter selections.

   ✱ NOTE: You can use Sort to sort the list by Vehicle Name, and Date.

4. Select Edit for the corresponding recorded acceleration event to provide more details.

The Add or Edit Collision Details popup window is displayed.



5. (Optional) You can change or update Did this collision occur?.
6. Complete the questionnaire, then select Apply changes.

You have successfully provided additional information on a recorded acceleration event.

Viewing more details on an event

Use Finding recorded acceleration events to narrow down the list of recorded acceleration events, then select the Vehicle Name.

The page refreshes to provide more details on the selected vehicle’s recorded acceleration event and a map view of where the recorded acceleration event was detected.

Use Center on map to move the map back to the location where the vehicle collision was detected, or Back to return to the Enhanced Accelerometer Experiment page.
