I haven't officially weighed in in this thread yet, so here goes...
• Project management: Sure. I've been here since the beginning, and have a good solid understanding of what's involved.
• General programming (likely in Unix environments): "general programming" sounds vague enough, so I'll tentatively raise my hand. Hey, I'm running two flavours of Linux!

• Web development: other people's abilities surely exceed mine. But I may be able to offer some JavaScript / GMaps API / HB pointers & tweaks...
• Algorithms to analyze the data: I anticipate things will likely be written in PHP, which I'm not fluent in. But it has been on my backburner of things I want to learn, and maybe this project can help in that. I can probably suss things out to some degree by looking at examples of code. I can also see myself contributing by discussing things in pseudocode -- although my pseudocode looks like C++.

• Highway system maintenance and development: I've continued to maintain the systems in AR, CT, KS, ME, ND, NE, NH, OK, RI, TX, and VT in the USA, and AB, MB, NB, NL, NS, and PE in Canada. Some new systems are forthcoming in these regions as well.
I'll also volunteer for review of new and existing systems, and am open to discussion of potentially reworking the way we do things WRT Peer Review.
• As Oscar noted, I could also help with training of new team members, but I'm hesitant: with less time availability on my plate as when I was at my previous job in/before 2013, I may not be able to keep up with the commitment very well.
• On the web side, I know some basic HTML and have picked up some JavaScript recently. I've dabbled with the GMaps API over the years as well, and made some HB type applications for my own use. I may be able to assist in getting a new HB running.
Of particular interest, I developed a JavaScript map generator with some help from vdeane. I shared the code with SSOWorld and he made some improvements, but I haven't really done any work since January 2nd. Nonetheless, it's a solid proof of concept, and a good ways toward implementing maps in the final product.
