I was using Canny for indoor images, but for outdoor I find more suitable the Laplace filter and Sobel filter, than apply Probabilistic Hough line Transform (PHT).

If u want to thicker your lines, you should try the Sobel operator after Laplace and finally the PHT. If your image is too nosy it might get worse.
