## Introduction
This library intends to provide a C++ implementation of the Responsibility Sensitive Safety model (RSS) for Automated Vehicles.
RSS is described in the following paper. Potential users of this C++ library are encouraged to read these papers in order to become familiar with the concepts and functions provided by the library.
* On a Formal Model of Safe and Scalable Self-driving Cars, S. Shalev-Shwartz, S. Shammah, A. Shashua, Mobileye, arXiv:1708.06374, [https://arxiv.org/abs/1708.06374](https://arxiv.org/abs/1708.06374)
The RSS module in this library receives (processed) sensor information as input and provides actuator command restrictions as output. The input to the RSS module is an object list, with information about all objects (road agents) in the surrounding environment of the ego vehicle. For each object, the RSS module creates a description of the object-ego vehicle pair and their properties, called a "situation". For each situation, the relevant RSS safety checks are performed and a proper response is calculated. Finally, one overall response is obtained by combining the responses calculated for each object-ego vehicle situation. The resulting actuation command restrictions, in the form of longitudinal and lateral limits on acceleration are provided as output.
The ad_rss library contains a stand-alone C++ implementation of the RSS module.
* Conversion of AV sensor data to the input object list required by the RSS module is outside the scope of the ad_rss library. This includes conversion of object location and motion in a Cartesian world coordinate system into a constellation based coordinate system.
* Conversion of the output proper response and acceleration restrictions to real AV actuation commands (enforcing the restrictions) is outside the scope of this library. This conversion depends strongly on the software and hardware setup of the actual (or simulated) vehicle.
The scope, design and architecture of this C++ library for RSS is described in more detail in the following document packaged with this release. This documentation includes guidance on the usage of the RSS library and its integration into a automated driving system. Users of this library are strongly encouraged to read this documentation prior to integration of the library.
### Integrating RSS with automated driving maps
When RSS is to be integrated into a larger system it is usually up to the user implementation to provide the required input into RSS based on the environment information
available within the system. The [*ad_rss_map_integration*](https://intel.github.io/ad-rss-lib/ad_rss_map_integration/Main/) library provides an example C++ implementation
for integrating RSS with automated driving maps.
### Usage of ad-rss-lib
If you use ad-rss-lib for any publication, please cite the IV'2019 paper:

```
#### Usage with Python
Starting with Release v1.6, it is possible to use the ad-rss-lib library also with Python.
Please see the [Documentation on the Python binding for ad_rss](https://intel.github.io/ad-rss-lib/ad_rss/ad_rss_python/index.html) or [ad_rss_map_integration_python](https://intel.github.io/ad-rss-lib/ad_rss_map_integration/ad_rss_map_integration_python/index.html) for further information.
#### Usage within CARLA
This library can be used together with the open-source driving simulator [CARLA](https://github.com/carla-simulator/carla) to investigate the behavior of RSS. A first version is shown in the following video sequence:

#### Usage within Baidu Apollo
In addition, the library is already integrated and used in Baidu's [Apollo Open Platform stack](https://github.com/ApolloAuto/apollo):

## Releases
General release notes and changes can be found in the [Changelog](https://intel.github.io/ad-rss-lib/CHANGELOG/index.html)
#### Release 4.x.x
These releases extends the 3.x version with handling of unstructured roads and pedestrians.
#### Release 3.x.x
These releases improve the 2.x version capabilities on constellation creation.
#### Release 2.x.x
These releases extend the 1.x version with map integration for extended usability.
#### Release 1.x.x
The initial release of the C++ software library for RSS implements a subset of the rules and calculations specified in the published RSS paper. This means that this release handles a subset of automated driving scenarios, described below. Scenarios other than this subset cannot be handled.
##### Features & Limitations
This release implements the RSS calculations and rules corresponding to the following scenarios:
* Multi-lane roads, i.e. longitudinal and lateral safe distance and proper response determination; and
* Intersections, i.e. two or more routes of different geometry, rules for intersections of routes, with priority/right of way, and longitudinal and lateral proper response determination. However, in the case of intersections, it is assumed that there is always a lateral conflict; and
* Unstructured roads and pedestrians.
The following parts of RSS are NOT implemented in this release of the library software:
* Occlusions;
* Longitudinal or lateral evasive maneuvers as defined by RSS; and
* Intersections without a lateral conflict.
Note: The RSS module in this library does not initiate evasive manuevers. At the same time, it would not hinder an evasive manuever being executed by the AV driving policy and planning modules, as long as it is compliant with the required RSS proper response.
#### Installation of dependencies
Currently, the focused operating systems are Ubuntu 20.04 and Ubuntu 22.04. Nevertheless, the library should work in a similar way for any other Linux OS.
To install the basic dependencies for Ubuntu 20.04/22.04 execute the following command:
```bash
user$> sudo apt-get install git build-essential cmake libboost-dev libpugixml-dev libgtest-dev libpython-dev libproj-dev

If you want to use doxygen for API documentation, please also install:
```bash
user$> sudo apt-get install doxygen graphviz

user$> cd ad-rss-lib
```
#### Supported systems
