Method and system for using cellular date for transportation planning and engineering
Using data from a wireless telephony network to support transportation planning and engineering. Data related to wireless network users is extracted from the wireless network to determine the location of a mobile station. Additional location records for the mobile station can be used to characterize the movement of the mobile station: its speed, its route, its point of origin and destination, and its primary and secondary transportation analysis zones. Aggregating data associated with multiple mobile stations allows characterizing and predicting traffic parameters, including traffic speeds and volumes along routes.
1. A method for providing an origination-destination matrix comprising the steps of:
identifying a trip initiation event for a trip associated with a mobile station;
determining a transportation analysis zone associated with the trip initiation event;
identifying a plurality of location records associated with the trip for the mobile station, wherein the location records comprise locations of the mobile station after the trip initiation event;
identifying a destination point associated with the trip, wherein the destination point comprises one of the plurality of location records and the location record represents the final location of the mobile station;
determining the transportation analysis zone associated with the destination point; and
recording the origination and destination of the trip in the origination-destination matrix, the origination being the transportation analysis zone associated with the trip initiation event and destination being the transportation analysis zone associated with the destination point, wherein the origination-destination matrix comprises at least two dimensions wherein a first dimension comprises a plurality of transportation analysis zones within a geographic area associated with an origin of a trip and the second dimension comprises a plurality of transportation analysis zones within a geographic area associated with a destination of a trip.
2. The method of claim 1 further comprising the step of estimating the movement of traffic through a geographic region comprising the transportation analysis zone associated with the trip initiation event and the transportation analysis zone associated with the destination point within a certain period of time.
3. The method of claim 1 further comprising the step of characterizing the purpose of the trip.
4. The method of claim 3 wherein the step of characterizing the purpose of the trip comprises determining whether the trip is to the user of the mobile station's location of work.
5. The method of claim 1 further comprising the steps of determining if the location associated with the trip initiation event is the residence of the user of the mobile station and determining if the location associated with the trip initiation event is the either the workplace of the user of the mobile station or a commercial retail location visited by the user of the mobile station.
6. The method of claim 1 further comprising the steps of determining a primary transportation analysis zone for the mobile station.
