Abstract

Methods, systems and processor-readable media for collecting vehicle data utilizing an agent-based road transportation modeling and simulation. An object can be defined to hold a vehicle and a distance can be measured along a road path from one end of a road section having a constant number of lanes and no merge and split point in the middle. A collection object can be defined to hold the defined object on a particular lane within one section of the road. A collection object can be defined to hold the above defined collection objects of one lane on a particular road section. Finally, A collection object can be defined to hold the above defined collection objects of one road section. Insert, remove and other functions can be defined to conduct a lane switch and/or other operation.

Claims

1. An agent-based road transportation modeling and simulation method, said method comprising:

defining an object to maintain a representation of a simulation of a vehicle and thereafter measure a distance along a simulated road path from one end of a simulated road section thereof having a plurality of lanes without a merge and a split point in a middle of said simulated road section;

defining a lane collection object to hold said defined object on a particular lane of said plurality of lanes within said simulated road section, a road section collection object to maintain said lane collection object on a particular simulated road section, and a road network collection object to maintain said road section collection on a particular simulated road network; and

defining insert, remove and other functions to conduct a lane switch and/or other operation and therefore analyze and assess traffic congestion and conditions with respect to said simulated road section.

2. The method of claim 1 further comprising configuring said lane collection object to include an array of length to be determined and/or preferred to be ordered by said distance.

3. The method of claim 1 further comprising configuring said road section collection object to include an array of lane collection objects of length of lane number on said particular road section.

4. The method of claim 1 further comprising configuring said road network collection object to include an array of road section collection objects of length of road section number on said simulated road network.

5. The method of claim 1 further comprising defining a sort function if said plurality of data fields with respect to said simulation of said vehicle is not sorted.

6. The method of claim 1 further comprising configuring said plurality of data fields to include provide at least one of the following types of data:

data indicative of an increase in speed of said vehicle;

data indicative of a slowing in speed of said vehicle;

data indicative of a breakdown of said vehicle;

data indicative of a following on of said vehicle; and

data indicative of a lane switch by said vehicle.

7. The method of claim 1 further comprising determining data indicative of a location of said vehicle and a location of a neighbor vehicle with respect to said vehicle utilizing data contained in said plurality of data fields, in order to maintain said vehicle object in said agent based modeling and simulation.

8. The method of claim 5 further comprising determining data indicative of a next move of said vehicle by said neighbor vehicle.

9. An agent-based road transportation modeling and simulation system, said system comprising:

a processor;

a data bus coupled to said processor; and

a computer-usable medium embodying computer code, said computer-usable medium being coupled to said data bus, said computer program code comprising instructions executable by said processor and configured for;

defining an object to maintain a representation of a simulation of a vehicle and thereafter measure a distance along a simulated road path from one end of a simulated road section thereof having a plurality of lanes without a merge and a split point in a middle of said simulated road section;

defining a lane collection object to hold said defined object on a particular lane of said plurality of lanes within said simulated road section, a road section collection object to maintain said lane collection object on a particular simulated road section, and a road network collection object to maintain said road section collection on a particular simulated road network; and

defining insert, remove and other functions to conduct a lane switch and/or other operation and therefore analyze and assess traffic congestion and conditions with respect to said simulated road section.

10. The system of claim 9 wherein said lane collection object is configured to include an array of length to be determined and/or preferred to be ordered by said distance.

13. The system of claim 9 further comprising wherein said instructions are further configured for defining a sort function if said plurality of data fields with respect to said simulation of said vehicle is not sorted.

14. The system of claim 9 further wherein said plurality of data fields is configured to include provide at least one of the following types of data:

data indicative of an increase in speed of said vehicle;

data indicative of a slowing in speed of said vehicle;

data indicative of a breakdown of said vehicle;

data indicative of a following on of said vehicle; and

data indicative of a lane switch by said vehicle.

15. The system of claim 9 wherein said instructions are further configured for determining data indicative of a location of said vehicle and a location of a neighbor vehicle with respect to said vehicle utilizing data contained in said plurality of data fields, in order to maintain said vehicle object in said agent based modeling and simulation.

16. The system of claim 13 wherein said instructions are further configured for determining data indicative of a next move of said vehicle by said neighbor vehicle.

17. A processor-readable medium storing code representing instructions to cause a process to perform a process for agent-based road transportation modeling and simulation, said code comprising code to:
