Communication techniques for transportation route modifications

A portable wireless data transfer and display device comprising:

• a user interface;
• a communication module;
• a display;
• a short-range wireless communication module configured to wirelessly receive vehicle data from a data acquisition device mounted inside a vehicle when in close proximity to the data acquisition device;
• wherein the portable wireless data transfer and display device is configured to accept inputs of driver information from a user via the user interface, the driver information including hours of service records for drivers associated with the portable wireless data transfer and display device;
• a long-range wireless communication module configured to send the vehicle data and the driver information associated with a current route of the vehicle through the communication module to a network device via a long-range wireless network;
• wherein the long-range wireless communication module is configured to receive at least one work request and an indication of a modified route, relative to the current route of the vehicle, corresponding to the work request from the network device via the long-range wireless network, the work request being in response to the current route of the vehicle and corresponding to at least one shipment to be delivered or altered;
• wherein the portable wireless data transfer and display device is configured to present the work request via the display and to accept an input from a driver responding to the work request via the user interface, wherein the input indicates whether the driver accepts or rejects the work request;
• wherein the portable wireless data transfer and display device is configured to forward the input from the driver responding to the work request to the network device via the long-range wireless communication module and the long-range wireless network;
• and
• wherein upon acceptance of the work request by the driver, the portable wireless data transfer and display device is configured to present the modified route via the display, wherein the modified route is either received, by the long-range wireless communication module, from the remote network device or calculated, by the portable wireless data transfer and display device, based on at least one of one or more updated route parameters or one or more inputs from the driver.
