Method and apparatus for route planning
The technology disclosed relates to a method for demand-response scheduling that resolves the most undesirable issues intrinsic to the paradigm of the prior art, namely constructing schedules by “Trip by Trip Insertion” onto service vehicles called routes. These issues are classified into Customer Service, On-time Performance, and Efficiency categories. The first step of the 2-step process is to globally build packets to patterns in a library that provide good Customer Service, On-time Performance protection, and Positive Ridesharing Efficiency. The packets are “Mini-Manifests” that meet all constraints, and once formed, are locked from modification by any subsequent scheduling action. The second step is to globally build routes by chaining packets together, controlled by configurable heuristic strategy. The routes that are built directly resolve the undesirable issues.
1. A route programming computer system, comprising:
a processor that is configured to execute programmed instructions to:
access a trip attributes table stored in a computer memory, the trip attributes table including trip parameters for each of a plurality of trips;
access a vehicle attributes table stored in the computer memory, the vehicle attributes table including vehicle data for each of a plurality of vehicles upon which the trips can be scheduled;
generate a plurality of packets,
wherein each of the plurality of packets includes one or more of the plurality of trips such that each trip in the packet meets one or more defined quality criteria and can be serviced by at least one of the plurality of vehicles, and
wherein, for each of the plurality of packets, one of the plurality of the trips can be added to the packet after the packet is generated; and
combine two or more of the plurality of packets into a route for one of the plurality of vehicles.
2. The route processing system of claim 1 , wherein the processor is configured to execute the programmed instructions to determine a direction of travel for each of the plurality of trips and to group one or more of the plurality of trips that have pickup locations that are within a predetermined geographic distance of each other and that are travelling in the same direction of travel to generate at least one of the plurality of packets.
3. The route processing system of claim 1 , wherein the processor is configured to execute the programmed instructions to determine a direction of travel for each of the plurality of trips and to group one or more of the plurality of trips that have drop off locations that are within a predetermined geographic distance of each other and that are arriving from the same direction of travel to generate at least one of the plurality of packets.
4. The route processing system of claim 1 , wherein the processor is configured to execute the programmed instructions determine a direction of travel for each of the plurality of trips and to group one or more of the plurality of trips that are travelling in the same direction of travel and that do not add more than a defined maximum extra distance to generate at least one of the plurality of packets.
5. A route programming computer system, comprising:
a processor that is configured to execute programmed instructions to:
access a trip attributes table stored in a computer memory, the trip attributes table including trip parameters for each of a plurality of trips;
access a vehicle attributes table stored in the computer memory, the vehicle attributes table including vehicle data for each of a plurality of vehicles upon which the trips can be scheduled;
generate a plurality of packets,
wherein each of the packets includes one or more of the trips such that each trip in the packet meets one or more defined quality criteria and can be serviced by at least one of the vehicles; and
wherein, for each of the packets, none of the trips can be added to the packet after the packet is generated; and
chain at least a first packet and a second packet of the plurality of packets together into a route for one of the vehicles, wherein the route specifies that the one of the vehicles is scheduled to service the first packet at least partially before the second packet.
