I want to make Collision warning and emergency braking in veins with SUMO, but I find I can't make the two vehicles collide in SUMO. So What should I do to make the two vehicles collide in SUMO?

I am solving the Google Foobar - Escape pods problem on level 4, and I faced a problem on test case N.4 which never passes! I've got only two days till the deadline and cannot figure out what is the problem with my code on that case. Is there anyone who can take a look or can provide me with some test cases in which my code fails? Here is the question:

You've blown up the LAMBCHOP doomsday device and broken the bunnies out of Lambda's prison - and now you need to escape from the space station as quickly and as orderly as possible! The bunnies have all gathered in various locations throughout the station, and need to make their way towards the seemingly endless amount of escape pods positioned in other parts of the station. You need to get the numerous bunnies through the various rooms to the escape pods. Unfortunately, the corridors between the rooms can only fit so many bunnies at a time. What's more, many of the corridors were resized to accommodate the LAMBCHOP, so they vary in how many bunnies can move through them at a time.

Given the starting room numbers of the groups of bunnies, the room numbers of the escape pods, and how many bunnies can fit through at a time in each direction of every corridor in between, figure out how many bunnies can safely make it to the escape pods at a time at peak.

Write a function solution(entrances, exits, path) that takes an array of integers denoting where the groups of gathered bunnies are, an array of integers denoting where the escape pods are located, and an array of an array of integers of the corridors, returning the total number of bunnies that can get through at each time step as an int. The entrances and exits are disjoint and thus will never overlap. The path element path[A][B] = C describes that the corridor going from A to B can fit C bunnies at each time step. There are at most 50 rooms connected by the corridors and at most 2000000 bunnies that will fit at a time.

How can I set the vehicle to drive at a constant speed? I find the speed of vehicle increases firstly and then drive at speed between 14.5 and 14.7 m/s in sumo. But I want the car drive at a constant speed in sumo. What shuould I do?

I want to get the closest node to a lat long pair from osmnx.

After i download the osmnx graph object i want to project it so i can remove dead ends from the road network as instructed in the docs.

I am aware that i project the graph and the lat, long values need to projected to but i dont actually understand in which way.

For example i have a conversion of lat long to x y z in my project but how can i know that this is compatible with the projection that this graph does. The euclidean method does not seem to help.

Also does the flag rebuild_graph=True undo the projection and return an unprojected graph obejct? If so the lat long data are not so close together to explain the same node being returned.

I am trying to find all the paths in a graph. I found this amazing function that I reproduce here:

So, basically, I'm trying to code a program that solves mazes. I did many tests with different mazes and I realize that my program isn't able to solve all kinds of mazes, only a few, since there some specific dead ends that my program gets stuck and cannot go back.

The logic behind my code is basically something that runs all over the maze until it finds the exit, and, if it finds a dead end during this processes, it should be able to go back and find a new unexplored path.

My code was working well until I start to test it with more complex mazes with different kinds of tricky dead ends. For Example:

I am using OSMnx to get clean intersections from OpenStreetMaps road network. The intersection nodes are currently in (x,y) coordinates, but I want to plot them using lat lon coordinates.

From the example Jupiter notebook, OSMnx Example #14 Clean Intersection Cluster Nodes, I am able to get the street network and call ox.clean_intersections to produce the clean intersections.

Hi I am using sumo to generate traffic flow and trying to find a way to tune the parameters conveniently. So I want to use a variable to replace the parameter in the body of the net file. From the web, I found that entity may be helpful, but it seemed that I have made some mistake. The code, var_test.net.xml, is as following.
