    memory configured to be in communication with the one or more processing units, the memory storing instructions that in accordance with execution by the one or more processing units, cause the one or more processing units to;

    receive encoded traffic conditions for at least a portion of a road, the encoded traffic conditions comprising a first traffic condition for a first section of the portion of the road and a second traffic condition for a second section of the portion of the road;

    package, for access by a graphics processing unit (GPU), the first traffic condition in a first array of a texture data file;

    package, for access by the GPU, the second traffic condition in a second array of the texture data file;

    process, by the GPU, the first traffic condition and the second traffic condition within the texture data file;

    determine a first color corresponding to the first traffic condition based at least in part on a color lookup table;

    determine a second color corresponding to the second traffic condition based at least in part on the color lookup table; and

    render a digital map based at least in part on geometric map information, the digital map including visual representations of current traffic conditions that include;
