Abstract

A database of high risk locations is formed and high risk causal factors for the high risk locations determined. Driver behavior is monitored at the sites in the database using data collection devices such as electronic logging devices or mobile phones to see if the drivers exhibit the same specific behaviors that are considered contributing factors to specific accident types at risk of occurrence at those sites. Warnings are provided to drivers approaching the specific sites to prompt behavioral changes which may further be monitored by the data collection devices.

Claims

1. A method of driver risk assessment, comprising:

maintaining a database of high risk locations, in which database each high risk location is associated with driver behaviors that are considered high risk in relation to the respective high risk location;

collecting driver behavior data for a vehicle that is indicative of driver behavior at a high risk location that is included in the database, using a data collection device in the vehicle;

comparing the driver behavior data to the driver behaviors considered high risk in relation to the high risk location to determine a value or values representing driver risk; and

flagging a driver whose driver risk value or values exceed predetermined risk criteria.

2. The method of claim 1 further comprising the data collection device detecting that the vehicle is approaching a high risk location of the database of high risk locations, and on the data collection device detecting that the vehicle is approaching the high risk location, displaying a visual warning to the driver of the vehicle.

3. A method of improving driver safety, comprising:

maintaining a database of high risk locations;

monitoring a location of a vehicle using a data collection device in the vehicle; and

providing a visual warning display to a driver of the vehicle on the vehicle approaching a high risk location recorded in the database of high risk locations.

4. The method of claim 3 in which each high risk location recorded in the database of high risk locations is associated with driver behaviors considered to be high risk in relation to the respective high risk location, the method further comprising the steps of:

collecting driver behavior data that is indicative of driver behavior at a high risk location that is included in the database using the data collection device;

comparing the driver behavior data to the driver behaviors considered high risk in relation to the high risk location to determine a value or values representing driver risk; and

flagging a driver whose driver risk value or values exceed predetermined risk criteria.

5. The method of claim 4 in which the visual warning comprises driving instructions.

6. The method of claim 5 further comprising contextual modification of the driving instructions based on instantaneous measurement of vehicle and driver status.

7. The method of claim 6 comprising displaying the driving instructions based on vehicle speed exceeding a specified limit, or based on driver HOS data exceeding a given threshold.

8. The method of claim 3 in which the visual warning display comprises driving instructions.

9. The method of claim 8 further comprising contextual modification of the driving instructions based on instantaneous measurement of vehicle and driver status.

10. The method of claim 9 further comprising displaying the driving instructions based on vehicle speed exceeding a specified limit, or based on driver HOS data exceeding a given threshold.

11. The method of claim 8 in which each high risk location recorded in the database of high risk locations is associated with driver behaviors considered to be high risk in relation to the respective high risk locations, the method further comprising the steps of:

collecting driver behavior data at the respective high risk locations;

comparing the driver behavior data from vehicles whose drivers were shown the visual warning to driver behavior data from vehicles whose drivers were not shown the visual warning, the comparison being carried out with respect to the driver behaviors considered to be high risk in relation to the respective high risk locations; and

on the comparison finding that the visual warnings displays are not effective at reducing driver behaviors considered high risk in relation to an accident location, ceasing to provide the visual warning displays at the high risk location.

12. The method of claim 3 in which each high risk location recorded in the database of high risk locations is associated with driver behaviors considered to be high risk in relation to the respective high risk locations, the method further comprising the steps of:

collecting driver behavior data at the respective high risk locations;

comparing the driver behavior data from vehicles whose drivers were shown the visual warning to driver behavior data from vehicles whose drivers were not shown the visual warning, the comparison being carried out with respect to the driver behaviors considered to be high risk in relation to the respective high risk locations; and

on the comparison finding that the visual warnings displays are not effective at reducing driver behaviors considered high risk in relation to an accident location, ceasing to provide the visual warning displays at the high risk location.
