Generate scene infrastructure including road and walkway meshes for any location on earth using OpenStreetMap data, then simulate traffic and pedestrians. Bridges, tunnels, traffic lights included.

可编程渲染管线（SRP）兼容性

Unity可编程渲染管线（SRP）是让您能够通过C#脚本控制渲染的一个功能。SRP是支撑通用渲染管线（URP）和高清渲染管线（HDRP）的底层技术。

描述

This package contains a procedural mesh generator to build fully functional roads and walkways, including bridges, tunnels, roundabouts, traffic lights, etc. It is suitable for simulation games where you want to quickly produce multiple levels based closely on real places. The package allows you to specify a location box anywhere on earth, then build a detailed 3D model of all roads and walkways within that location box.

This package also contains a traffic and pedestrian simulator. Coding skils are required to use the simulator. Traffic includes cars, buses, taxis and trucks that move using industry-tested, peer-reviewed car-following and lane-changing algorithms. The package includes a code library that you can use to control the simulation, down to the level of individual vehicles and pedestrians. See API at https://vroad.uk/api

The scene generator runs on Windows/Mac/Linux, while the simulation can run on these and on Android and iOS. see our website for an example game: https://vroad.uk

An optional feature is that you can decorate the terrain by downloading terrain elevation and aerial image data from mapbox.com, if you register and create an account with them. This does not require any payment to Mapbox unless you exceed their free tier. If you do not register a Mapbox account, the only difference you will see is that the underlying terrain will be flat, and will be rendered with a plain texture of your choice.

技术细节

Features of Scene Generator

Import data from OpenStreetMap (OSM) from anywhere on earth
OSM Import includes roads, walkways, building and water outlines
Build a terrain surface with holes for tunnels
Roads fitted to terrain, terrain modified where road gradients would be excessive
All intersections created automatically, including roundabouts, at-grade (single-level) and grade-separated (multi-level)
Sidewalks, footpaths and pedestrian crossings created

Features of Simulator

Multi-threaded implementation, makes full use of multiple cores
Uses peer-reviewed car-following and lane-changing models
Realistic traffic signal logic created for all junctions tagged as signalized in OSM
Pedestrians simulated walking between points of interest
Support for two-part articulated vehicles in addition to single-part fixed vehicles
A few simple prefabs for vehicle models and a single basic animated ped are included - this tool is designed with the intention that you drop in your own models for cars, trucks, buses, and people in the simulation, to suit the style of your application

Pro Features

Create maps up to 1600 Ha in area. This is 4x4 km square, or 5.33x3 km at 16:9 aspect, or about 800 typical US city blocks
Create automated taxis that can carry people in the simulation, so that a person can walk, then ride a taxi, then walk, all as part of the same trip.
Import bus routes and bus stops from OSM and then create buses on these routes that carry people in the simulation between bus stops.

System Requirements

Scene generator runs in Unity Editor on Windows/Mac/Linux
An internet connection is required to download OSM and terrain data. No connection is required once data is downloaded and scene built.
Simulation runs locally on Windows/Mac/Linux/Android/iOS

Optional Terrain and Aerial Images from Mapbox

For maximum clarity: a MapBox account is not required to run this package. You can choose to enable this feature if you want to create a terrain based on satellite elevation data, textured with an aerial image.
If you decide to use this option to decorate the terrain, you will probably not incur any charges. At the date of this release, there is a generous free tier, a charge would be incurred only if you exceed this free tier. The relevant pricing plans are shown here: https://www.mapbox.com/pricing#maps - see the section on Raster Tile API
If you do not register a Mapbox account, the only difference you will see is that the underlying terrain will be flat, and will be rendered with a plain texture of your choice.
