Separate input concatenation in segnet

[ShastriRam]

This isn't so much an issue, but I am seeking some advice and assistance. I am using segnet for outdoor terrain recognition. I have my raw images, as well as my labelled images. I would also like to include as input into the network, the speed at which the robot was driving when the images were taken. To be more specific, for each image, I would have an associated velocity in float format. How would I go about doing this? I am using the attached prototxt. I would really appreciate any help.
