Traffic simulation

Just wanted to show off a traffic simulation I made with generous help from the community.

*Note: Lag only caused by video capture. Lag is not present in game simulation.

 

I've played around in this, works really good. Really fun to just drive around and avoid crashing.

 

Edited:

PM me for standalone link.

 

That's really nice man! I need something like this for my car-combatants game I'm working on. I'm guessing you used raycasting for the traffic to avoid obstacles and just paths for the roads or something?

 

Yes! Raycasting is used to detect objects. Paths per road are used, then paths are assigned at the beginning of an intersection.

 

Very cool Carking, I would love to see more info on how it works, what makes this thing tick? Agent driven?

Oh i tried getting the webplayer going, but it didn't work for me, i hit "cruise" and it took me to an empty room, where back and drive were the options, but drive didnt seem to do anything, hit back, then tried "race" but that also did nothing for me :/

 

The vehicles are based on 1 set of 4 waypoints per street(4 for a 4-laned road, or also 2 for a 2-laned road). The web player is down, I should probably remove that link.

Everyone, the system is for sale! PM me to check it out!

 

Here's another stress test of my Unity3D traffic simulation system. On the screen are just under 60 vehicles driving themselves around the environment. The only limits to the amount of vehicles are your vehicle draw culls, but that's for you to get down.

Updates are random turning for right lanes and optimizations. I think it shows well!

I have decided to model a city around it. Take a look!

 

Looks good CarKing! Are they rigidbodies? Fully detailed cars with whellcolliders, or just transforms with colliders and raycasts? Also, the cars seem to slow to a stop way too quickly behind other cars, but maybe I'm just a weird driver in real life

 

They have full physics, wheelcolliders and rigidbodies. Here's another video.

 

Some updates:
-Stop signs work. Vehicle checks if traffic is on the road. If there are traffic, it stops and waits. If not, it just goes.
-Tail light implementation.
-Random speeds based on Random.range.
-One-way streets work now, too.

 

Super good job. Can you show how you setup roads.

 

I'll show a video later. I'm also adding pedestrian support tonite.

 

It looks slerp/lerp based rather than physics based. Is that correct?

 

Nope. Full wheel collider physics. I've created this in less than two minutes with the editor pieces I wrote.

 

Here's a video of it in use.

 

Testing out the pedestrian simulation.

 

Bump. Whatcha guys think?

 

I like it alot Keep it up, the only thing i don't like is the pedestrains because they all go the same path, but that can probably be changed, not sure but i bet it is a work in progress

 

More variation in pedestrians moving, also maybe more realistic car physics? Pretty hard I know.

 

Some things I'm planning:

-Taxis with stops
-Buses with stops
-Peds sitting on benches
-Peds standing around, talking

Thanks for your comments, guys.

 

This system looks great.

Is it already available. If so where can I get it?

 

It's for sale. You can PM me for any questions.

 

Ive seen this in action, and i definitly recommend buying this!

 

Hey I am currently using this, is there anyways to loop paths and/or delete at the end of the path?

 

The paths currently do not loop, but I have a AI code that does, or you can just set the PathSelector at the end and begin the path again. And you can make it delete your car at the end if you need.

Ohh, if the end of the path is at the beginning (path selector) They will not wander off, but go back to the beginning of the path?

 

Yes, just add the path selector trigger and script on it. Check out the intersections, as they have them.

 

Hmm, Ill try that, last time I tried to do something with the path selector I clicked it on the UI and nothing happened, and which script are you referring to. Sorry, still trying to get the ropes

 

Looks pretty good

 

Hello, here's an image of what you could do. Go to the objects inside the traffic light object with this script, "GetThePoints". This script allows you to assign a path to which the traffic in that lane will go to. Simply make the path almost closed, and put one of these triggers with the script(assigned to the path), at the end. It will then simply go to the same path over and over without stopping.

 

Whats the latest version? I tried that last night but even in the demo after the first trigger all the cars just veer off onto the sidewalks or into each other. Is it possible you can send me an updated version?

 

The demo scene isn't really much of anything. It's a few roads not even connected. I should redo it.

 

Ok I will try what you said, and let you know.

 

Ok I have been trying all day to get the cars to get on a path from the trigger like you showed buts its simply not working everytime. This is the result everytime :







I did both the first point on the path in the get points variable and the whole path itself, I also checked, unchecked navigate and get points and still the same thing. Please let me know if you see something Im doing wrong

 

Can you show a video on what you're doing? You don't set the first point. You set the whole path object, the parent of the path.

 

Ive sent you a PM with the video link.

 

Still looking great! One thing I would suggest is to make a naming convention for the "paths" and "intersections" objects, so they follow a scheme like Path_001, Path_002, Intersection_001 and so forth. Other than that I am really impressed how far you have taken this project! Could I ask publicly what the price of the asset is? And are all the models and scenes in the video demos available when you purchase?

 

I've sent you a pm.

 

Hi, when i switch the project to Android, i get this error;
AICar_ScriptTr.js(50,28): BCE0019: 'transform' is not a member of 'Object'.
AICar_ScriptTr.js(51,45): BCE0019: 'transform' is not a member of 'Object'.

 

Replace line 18 in the AI_CarScriptTr code with:

Code (JavaScript):

1. private var waypoints : Transform[];

 

this time another error;
IndexOutOfRangeException: Array index is out of range.
(wrapper stelemref) object:stelemref (object,intptr,object)
AICar_ScriptTr.GetWaypoints () (at Assets/Scripts/Car Control/AICar_ScriptTr.js:101)
AICar_ScriptTr.FixedUpdate () (at Assets/Scripts/Car Control/AICar_ScriptTr.js:49)

 

Odd. Let me check this.

 

any solution for this?

 

Still trying to figure out a workaround for it. I had fixed it for a past buyer, but don't have the exact code anymore. I'm looking for a fix.

 

we need in a mobile project, i sent you email, It would be great if you could go back

 

I'm still working out the bug. Taking some recoding.

 

still does not? I think we have to look to other projects, thanks anyway

 

Hello Carking - any updates from you on this project? Wish I saw this 2 years ago
