Abstract

A traffic monitoring system and method allow for remote monitoring of traffic sites by a plurality of users. A plurality of traffic monitoring devices record data related to traffic events. The data is encoded and communicated to a central server using wireless paging technology. The central server decodes and distributes the communicated data and makes the data available to a plurality of remote users. The remote users access the data, for example via the Internet, in order to remotely evaluate the traffic situation

Claims

1. A method of communicating vehicular-traffic-related data from a vehicular traffic monitoring device to a user comprising:

extracting vehicular-traffic-related data from a vehicular-traffic monitoring device;

encoding the collected vehicular-traffic-related data according to wireless paging protocol;

transmitting the encoded vehicular-traffic-related data over a wireless paging network to a server; and

receiving the transmitted encoded vehicular-traffic-related data at the server, to enable user access to the vehicular-traffic-related data via the server.

2. The method of claim 1 wherein extracting vehicular-traffic-related data from the vehicular-traffic monitoring device comprises periodically polling the vehicular-traffic monitoring device for updated vehicular-traffic-related data.

3. The method of claim 1 wherein encoding the collected vehicular-traffic-related data comprises:

encoding the vehicular-traffic-related data according to wireless paging protocol to enable vehicular-traffic-related data transmission in binary format to the server.

4. The method of claim 3 further comprising:

polling the wireless paging network to determine transmission availability; and

when available, transmitting the encoded vehicular-traffic-related data over the wireless paging network to the server.

5. The method of claim 1 wherein the decoded vehicular-traffic-related data received at the server is stored in a master mailbox and further comprising duplicating the stored vehicular-traffic-related data from the master mailbox to a user mailbox.

6. The method of claim 5 further comprising downloading the vehicular-traffic-related data in the user mailbox remotely from a PC workstation via the Internet.

7. The method of claim 6 wherein downloading further comprises:

establishing authenticity of the user;

downloading the vehicular- traffic-related data from the user mailbox to the PC workstation; and

interpreting and storing the vehicular-traffic-related data at the PC workstation.

8. The method of claim 1 wherein the server duplicates the received vehicular-traffic-related data to enable access to the vehicular traffic-related data by multiple users.

9. The method of claim 1 further comprising downloading the received and decoded vehicular-traffic-related data by a user via the Internet.

10. The method of claim 1 wherein the vehicular-traffic-related data includes volume, occupancy and speed.

11. A system for communicating vehicular-traffic-related data from a vehicular-traffic monitoring device to a user comprising:

a traffic monitoring device for collecting vehicular-traffic-related data;

a communication device for extracting vehicular-traffic-related data from the traffic monitoring device and encoding the extracted vehicular-traffic-related data according to a wireless paging protocol;

a pager modem for transmitting the encoded vehicular-traffic-related data over a wireless paging network; and

a server for receiving the transmitted encoded data to enable user access to the vehicular-traffic-related data via the server.

12. The system of claim 11 wherein the communication device periodically polls the traffic monitoring device for updated vehicular-traffic-related data and wherein the communicating device further comprises:

a processor having first and second data ports for respectively interfacing with the traffic monitoring device and the pager modem;

memory for hosting embedded software including traffic monitoring device interface protocol and wireless paging protocol, and for storing data.

13. The system of claim 12 wherein the communication device further periodically requests vehicular-traffic-related data from the traffic monitoring device, receives the requested vehicular-traffic-related data, encodes the vehicular-traffic-related data according to wireless paging protocol to enable vehicular-traffic-related data transmission in binary format to the server;

and stores the encoded data in the memory.

14. The system of claim 12 wherein the communication device further periodically polls the pager modem to determine transmission availability;

and when available, uploads the vehicular-traffic-related data to the pager modem to transmit the encoded vehicular-traffic-related data over the wireless paging network.

15. The system of claim 11 wherein the server stores the decoded vehicular-traffic-related data in a master mailbox and further comprising means for duplicating the stored vehicular-traffic-related data from the master mailbox to a user mailbox to enable multiple user access.

16. The system of claim 11 wherein the server provides for remote access to the user mailbox via the Internet.

17. The system of claim 16 further comprising a PC workstation coupled to the Internet to allow for remote access of user mailbox data over the Internet, the PC workstation including software enabling a user to:

establish user authenticity with the server;

download the vehicular- traffic-related data from the user mailbox to the PC workstation; and

interpret and store the vehicular-traffic-related data at the PC workstation.

18. The system of claim 11 wherein the server duplicates the received vehicular-traffic-related data to enable access to the vehicular traffic-related data by multiple users.

19. The system of claim 11 further comprising a remote PC workstation for downloading the received and decoded vehicular-traffic-related data by a user via the Internet.

20. The system of claim 11 wherein the vehicular-traffic-related data includes volume, occupancy and speed.
