Traffic optimization - how is it done?

Question

Algorithms

In the city where I live, there are traffic jams during rush hour. It is clearly visible that the traffic lights are set up incorrectly, well, and some other things are done incorrectly. As far as I understand, there is no unified management system.
How is traffic optimized today? Are there any works / manuals / books on this topic, tell me? How difficult is it to make a project yourself in order to offer it to the municipality?

Answer 1

A typical transport task. It is solved by the simplex method. To do this, you need to correctly compose equations and collect statistics on traffic flows.

Answer 2

Separate lane for municipal transport with bricks + parking spaces. And the air will become cleaner!

Answer 3

First you need to collect statistics (how many turn, how much straight, how long they stand in which directions). Then think about what to do (adding additional sections for turns, increasing the number of lanes from which left / right turns are allowed, etc.) But I think that the traffic police themselves are aware of the problem and think what can be done :)

Answer 4

Similar systems exist (for example, IBM Smarter Cities, read about them in local news), the problem is in the cost and complexity of implementation, because. if you do, then you need to immediately connect the entire city, a lot of things to change, update, etc., and this is extremely expensive and difficult. The order of implementation cost is tens to hundreds of millions of dollars, depending on the size of the city.

Answer 5

I read an article in the children's magazine Kvant, but I don't remember the year. Probably from 1984 to 1991.
There was an original article with its own methods, but for a simplified square nested city. Nevertheless, the model's rabbits were there, and, just in case, I put aside the fact that the article was in memory.

Answer 6

A complex dynamic task with social and other aspects.
The task is related to weighted graphs and dynamic load distribution, it is also worth considering that our drivers do not change the route so often depending on the situation and create traffic jams and much more ...
In general, there are a lot of aspects and problems. And a balanced and correct approach is very important.
Of the books, first of all, these are books on graphs and analytics, I will not say specific authors and titles, unfortunately.
