Receiver for traffic messages
First Claim
1. A traffic broadcast receiver comprising:
- a) a first memory for allocating received addresses to segments of a street system;
b) a device for reproducing received coded signals in clearly understandable form; and
c) an additional device, said additional device includingi) a second memory for storing travel parameters of the segments stored in the first memory and addresses allocated to the segments,ii) an input device for permitting the supply of at least one destination input which is to be allocated to a stored segment,iii) a computer adapted to determine the optimum route to the destination, andiv) a third memory in which segments forming the optimum route determined by the computer can be stored.

Abstract
A traffic broadcast receiver with a first memory (16) for allocating received addresses to segments (S1-S40) of a street system, and with a device (30) for reproducing the received coded signals in clearly understandable form, is equipped with an additional device (42) with a second memory (44) for travel parameters of the segments (S1-S40) stored in the first memory (16), and addresses for segments adjacent to the respective segment (S1-S40), with an input device (34) for at least one destination input which is to be allocated to a stored segment (S1-S40), with a computer (46) to determine the optimum route to the destination (ZP), and with a third memory (48) in which the segments belonging to the optimum route determined by the computer (46) can be stored. In conjunction with the segments (S1-S40) stored in the first memory (16), the additional device allows the reproduction of an optimum route, determined by the computer ( 46), to the destination that was entered.

22. In a traffic broadcast receiver including
a station receiver, a decoder, a first memory including a plurality of addresses and associated segments, the segments defining a road system, a memory device, a computer, an event memory, a second memory storing all links between segments stored in the first memory and storing length corresponding to each of the segments stored in the first memory, a third memory, a fourth memory storing travel parameter evaluation factors corresponding to each of the segments stored in the first memory, an input device, and an output device, a method for providing a route to a driver, comprising the steps of: -
a) determining a starting point; b) determining a first segment upon which the starting point lies based on the segments stored in the first memory; c) entering a destination point via the input device; d) determining a second segment upon which the destination point lies based on the segments stored in the first memory; e) computing an optimum route between the first segment associated with the starting point and the second segment associated with the destination point; f) writing the optimum route computed in step (e) to the third memory; and g) outputting the optimum route to a driver via the output device. - View Dependent Claims (23, 24, 25, 26, 27, 28)
