Abstract

Systems and methods are described to receive a safety preference; calculate a temporary route; analyze a portion of the temporary route to determine whether the portion is sufficiently safe based on the safety preference; modify the portion of the temporary route when the portion is not sufficiently safe; and present the temporary route. Other systems and methods are described.

Claims

1. A method comprising:

receiving a safety preference;

calculating a temporary route;

analyzing a portion of the temporary route to determine whether the portion is sufficiently safe based on the safety preference;

modifying the portion of the temporary route when the portion is determined not sufficiently safe; and

presenting the temporary route.

2. A method comprising:

receiving a plurality of travel preferences;

determining a weighting of each preference in the plurality of travel preferences;

determining a temporary route based on the weighting of each preference;

analyzing the temporary route to determine whether the temporary route is sufficiently safe;

modifying the temporary route when the temporary route is determined not sufficiently safe; and

presenting the temporary route.

3. A method comprising:

receiving a request to generate a travel route;

generating a temporary travel route using the request;

identifying a transportation structure in the temporary route;

accessing an inspection record corresponding to the transportation structure;

determining whether the transportation structure is sufficiently safe based on the inspection record;

modifying the temporary route when the transportation structure is determined not sufficiently safe; and

presenting the temporary route.

4. A system comprising:

a memory; and

a processing module coupled to the memory, wherein the processing module is configured to;

access a safety preference from the memory;

calculate a temporary route;

analyze a portion of the temporary route to determine whether the portion is sufficiently safe based on the safety preference;

modify the portion of the temporary route when the portion is determined not sufficiently safe; and

present the temporary route.

5. A system comprising:

a memory; and

a processing module coupled to the memory, wherein the processing module is configured to;

access a plurality of travel preferences from the memory;

determine a weighting of each preference in the plurality of travel preferences;

determine a temporary route based on the weighting of each preference;

analyze the temporary route to determine whether the temporary route is sufficiently safe;

modify the temporary route when the temporary route is determined not sufficiently safe; and

present the temporary route.

6. A system comprising:

a memory; and

a processing module coupled to the memory, wherein the processing module is configured to;

access a request to generate a travel route from the memory;

generate a temporary travel route using the request;

identify a transportation structure in the temporary route;

access an inspection record corresponding to the transportation structure;

determine whether the transportation structure is sufficiently safe based on the inspection record;

modify the temporary route when the transportation structure is determined not sufficiently safe; and

present the temporary route.

7. A computer-readable medium including instructions that, when executed on a computer, cause the computer to:

receive a safety preference;

calculate a temporary route;

analyze a portion of the temporary route to determine whether the portion is sufficiently safe based on the safety preference;

modify the portion of the temporary route when the portion is determined not sufficiently safe; and

present the temporary route.

8. A computer-readable medium including instructions that, when executed on a computer, cause the computer to:

receive a plurality of travel preferences;

determine a weighting of each preference in the plurality of travel preferences;

determine a temporary route based on the weighting of each preference;

analyze the temporary route to determine whether the temporary route is sufficiently safe;

modify the temporary route when the temporary route is determined not sufficiently safe; and

present the temporary route.

9. A computer-readable medium including instructions that, when executed on a computer, cause the computer to:

receive a request to generate a travel route;

generate a temporary travel route using the request;

identify a transportation structure in the temporary route;

access an inspection record corresponding to the transportation structure;

determine whether the transportation structure is sufficiently safe based on the inspection record;

modify the temporary route when the transportation structure is determined not sufficiently safe; and

present the temporary route.
