- Abstract
- This paper proposes a velocity data compression method for reducing redundancy in the traffic information. We focus on the repeatability of velocity between adjacent roads, and thus adopt variable length coding method. In addition, we define message format for transmitting traffic information. We call this velocity compression (VC) method. To verify the efficiency of proposed scheme, experimental environment is built up in a laboratory and experiments are executed by transmitting traffic data with and without VC method. The experimental results shows that our scheme utilizes Digital Multimedia Broadcasting network resource more efficiently rather than a method delivering uncompressed traffic information.
