Abstract
An approach is provided for determining a navigation route based on vulnerable road user data. The approach, for example, involves generating one or more candidate navigation routes for a vehicle. The approach also involves querying a geographic database for vulnerable road user data for a respective set of road links comprising each of the one or more candidate navigation routes. The approach further involves selecting the navigation route from among the one or more candidate navigation routes based on the vulnerable road user data.
Claims19
A computer-implemented method for determining a navigation route comprising:
- generating one or more candidate navigation routes for a vehicle upon identifying a destination of the vehicle;
- querying a geographic database for one or more physical dividers for a respective set of road links comprising each of the one or more candidate navigation routes;
- on detecting at least one vulnerable road user on at least one road link of the set of road links, setting a vulnerable road user attribute to below a threshold value based on a presence of the one or more physical dividers on the at least one road link, wherein the vulnerable road user attribute indicates a probability of a collision with the at least one vulnerable road user;
- selecting the navigation route from the one or more candidate navigation routes based on the vulnerable road user attribute, wherein the navigation route is selected to minimize the vulnerable road user attribute among the one or more candidate navigation routes;
- and
- using the selected navigation route to direct driving of the vehicle.
An apparatus for determining a navigation route comprising:
- at least one processor;
- and
- at least one memory including computer program code for one or more programs, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following:
- generate one or more candidate navigation routes for a vehicle upon identifying a destination of the vehicle;
- query a geographic database for one or more physical dividers for a respective set of road links comprising each of the one or more candidate navigation routes;
- on detecting at least one vulnerable road user on at least one road link of the set of road links, set a vulnerable road user attribute to below a threshold value based on a presence of the one or more physical dividers on the at least one road link, wherein the vulnerable road user attribute indicates a probability of a collision with the at least one vulnerable road user;
- select the navigation route from among the one or more candidate navigation routes based on the vulnerable road user attribute, wherein the navigation route is selected to minimize the vulnerable road user attribute among the one or more candidate navigation routes;
- and
- use the selected navigation route to direct driving of the vehicle.
A non-transitory computer-readable storage medium for determining a navigation route, carrying one or more sequences of one or more instructions which, when executed by one or more processors, cause an apparatus to perform:
- generating one or more candidate navigation routes for a vehicle upon identifying a destination of the vehicle;
- querying a geographic database for one or more physical dividers for a respective set of road links comprising each of the one or more candidate navigation routes;
- on detecting at least one vulnerable road user on at least one road link of the set of road links, setting a vulnerable road user attribute to below a threshold value based on a presence of the one or more physical dividers on the at least one road link, wherein the vulnerable road user attribute indicates a probability of a collision with the at least one vulnerable road user;
- selecting the navigation route from among the one or more candidate navigation routes based on the vulnerable road user attribute, wherein the navigation route is selected to minimize the vulnerable road user attribute among the one or more candidate navigation routes;
- and
- using the selected navigation route to direct driving of the vehicle.
