I would love to hear more

I'll see about getting some writing started. I keep getting asked to write a book. It was a pretty wild ride. I have a Ph.D. in Applied Mathematics and actually did my research with vehicular traffic because the date was free. I actually expected to remain in academia, but was given the chance to contract with a government agency, even before I'd done my defense. Basically, I helped take the art of traffic modeling t…

This is really interesting! Thanks for sharing. Is the vehicular traffic data you're referring to at the state level (i.e. do individual states report on it)? Or is it available for all states? And can anyone access it or is it only free for academic licenses?

Various States will have varied rules, but it is generally free. The Feds will also have stats for interstate routes.

In my case, the data was existent. I'd later collect data. Data is not just throughout, but even contains data from things like a reflectometer, sign frequency, and adjustments for specific locations.

The data collected is, for this sort of thing, paid for by the municipality and can be examined at your local municipality, where applicable. The specific department, and location, will vary but our reports were public information. Your department of transportation has copies, where applicable.

I didn't do much in the way of design. I modeled. This is what will happen if you do this, this is what will happen if you do that, and if you want these results you should consider doing these things. They don't always listen.

We also did modeling for things like disasters. A recent example would be the bridge collapse in Atlanta, GA. Most of the public thought it was going to be a nightmare. I actually had people argue with me and tell me I didn't know what I was talking about. No, they already have plans on file to deal with the expected congestion from just such an occurrence.

Of course, those plans are usually a bit out of date... In their defense, it's not an inexpensive process. Given the ubiquity of compute cycles, many municipalities are taking some of this in-house.

Your local planning board should be a good start, if you want to learn about your specific area.

Note: I have been out of the industry for about a decade. I am contractually barred from entering the industry again, in any capacity. I do try to keep up with the tech, but that's purely out of curiosity. It is no longer a scholarly or professional pursuit.

Also, any reports we filed are almost certainly still around. They are probably buried in a closet, however. I am not actually sure how municipalities function as well as they do. They are, almost without fail, very disorganized.

Someday, I'll tell you about The Font People. Yes, we even quantify fonts as an impact factor. However, Font People are some of the most unusual characters I've ever met - all of them.

I do miss the data collection and research. But, I haven't worn pants all day. So, it's an acceptable trade off.

For those that think that a 4% decrease (or equivalently a 5% increase) is not much, you should go ask your boss for a 5% raise and see what they think.

Isn't it more like tell your boss you'll take a pay cut, all it will cost is hiring your personal firm as efficiency consultants for £2M ... But look 5% reduction off your portion of the wage bill.

The contest prize was $15,000, there were probably some ancillary costs related to running the event but still quite cheap.

Since this forum for founder/entrepreneur types, let me inject a bit of caution from my own experience with dealing with government organizations: If you save a business organization money, they appreciate it. If you save a government organization money, the next year the "savings" is likely to be deducted from their budget. They don't get to benefit from the savings and thus their motivations aren't what you might e…

Plenty of business organizations behave exactly the same way, which is one reason for sales cycles in b2b services. Departments are willing to spend money at the end of a budget period on things they otherwise wouldn't have, divisions unwilling to reduce staffing because they may not get approval to hire more people later...

Exactly right: this is a pattern of bureaucratic empire-building versus smaller/flatter organizations, not one of government versus business institutions.

Fascinating story. Thank you for sharing! How long did it take you to build this company from start to exit?

What were some of the toughest moments you experienced?

And what advice would you give to people who want to build their own companies in transportation/logistics fields? (I know - may not be exactly your area but there may be some cross-sector knowledge sharing at play here!).

I worked with a startup years ago that did these kinds of optimizations (for deliveries). The logistics & transportation market in the US is about a TRILLION dollars -- small optimizations can make a HUGE impact. The challenge for practical implementations is that there are lots and lots and lots of optimization factors that are very hard to account for. Often, you don't even know what they are until you try to autom…

I modeled traffic. I sold my company and retired, years ago. People don't realize how complicated traffic really is. It's a chaotic system, of sorts. You can tease out patterns with some work. Anyhow, to add to your point, you can model all you want - but some drunk is going to reverse the wrong way down a one way street. One of these days, maybe I'll get around to putting my experiences into giant walls of text.

I am curious: do you know anything about rail?

I started it, unofficially, in 1991. The sale was finalized in late 2007. I started with loaned equipment from DEC, on an empty factory floor, with just myself and a fellow grad. He was a CS grad and we would later part peacefully. He never had ownership.

My toughest moments were people related. I never took any fancy business course that taught me how to manage people. I tried to micromanage and had a hard time letting go.

Eventually, we'd have three offices along the East Coast and a satellite office in the middle of the country. We had about 235 employees when i sold. What I learned was to stop trusting vendors.

I learned that I'd hired these people to do things that I could not do. If I could have dne them, I'd have not needed to hire them. Give them the tools they ask for, the room to do what they need, and clear goals.

They were different times. It was a Wild West sort of environment. It was hard enough getting engineers and programmers to wear shoes and a lot like herding cats. But, give them freedom and respect. Remember, you hired them because they were the very best you could find and they can do things you can not.

Advice? Be in the right place, at the right time, with specific skills, and in a position to take risks. Had I been unable to complete my first contract, the penalties were great enough that I'd still be paying them off - slight exaggeration.

It's pithy to say study hard and work hard, but that helps. I worked my ass off, often putting in 16 hour days. I'd continue to do this, even after being the sole custodial parent for my two kids. My ex wife is a bit of a mess. I missed a lot of their youth and they were often home with a girlfriend or a nanny.

But, find something that is missing and do it. Find something that is hard, and do it better. Right now, things look like a more intensive struggle for efficiency. How can you make transportation/logistics more efficient? How can you make it better? What services are lacking?

In my case, there weren't even many traffic engineers back then. The field, as applied by computers, was very young. The existent algorithms didn't scale or translate well to computers. I'm a horrible programmer, but I am a mathematician. I fixed that.

Similar processes applied to fleet management and to pedestrian traffic. Similar processes relate to outflow of people in buildings such as skyscrapers, shopping malls, and arenas. Even certain outdoor events need evacuation plans, for which modeling pedestrian behavior is important. Even your grocery store has probably modeled how you will move through it.

We had more work than we could do. I couldn't hire enough people and we just kept growing. I liked field work, so I tried to get as much time out in the field as I could. It also meant that I was on-site, a lot. I kinda hate dealing with government workers. They mean well, but they are tied to a dysfunctional environment.

Anyhow, soft skills matter. Be nice, polite, and an active listener. Listen for what they need, not what they are telling you they want. Be ready to try to provide both.

Sorry for the verbosity and disjointed post. I don't have words of wisdom, only my own experiences. I hate to admit it, but going to a good school probably helped a great deal initially. I went to MIT and just that was enough to open the doors. DEC literally loaned me equipment, both during grad work and to start the business. MDOT gave me loads of help and even followed my research from a fairly early point.

I'm open to continued responses, but I don't want to derail the thread too much.

That's also why third-party analysis of how government organizations spend their money is so crucial. Without such analysis, there is no check on wasteful spending.

They work for the people, after all.
