# How to run a simulation with shared AVs
Shared AVs can be activated via the `shared_av` config group:
```xml
<module name="shared_avs">
<!-- Defines whather shared AVs are active or not -->
<param name="useSharedAVs" value="true" />
<!-- Defines the fleet sizes of both services -->
<param name="taxiFleetSize" value="100" />
<param name="pooledFleetSize" value="100" />
<!-- Define a shape file for the operating area and zones for waiting time measurement therein -->
<param name="serviceAreaShapefile" value="path/to/service_areas.shp" />
<param name="waitingTimeZoneShapefile" value="path/to/waiting_time_zones.shp" />
<!-- Defines the relevant attribute names of the shapes in these shape files -->
<param name="serviceAreaAttribute" value="SAREA" />
<param name="waitingTimeZoneAttribute" value="WZONE" />
<!-- Defines which operating area is active -->
<param name="activeServiceArea" value="true" />
</module>
```
To run such a simulation, two shape files must be provided. The first is a file containing all the service areas for the scenarios (probably there will be exactly one per scenario). The path to that file must be given as the `serviceAreaShapefile` option. The shapes for these service areas must contain an attribute that can be configured via the `serviceAreaAttribute`. Finally, via config one can choose which of these areas is used in the next run by setting `activeServiceArea` to one of the possible values of that attribute, i.e. one selects one service area from this service area file.
Second, a file containing a segmentation of space for waiting time calculation must be given as `waitingTimeZoneShapefile`. Waiting times for the AV services are measured and predicted, for instance, in a grid. If the whole service area is one of these "waiting time zones", all waiting times in the service area will be averaged when predicting waiting times. The format of the shape file is again that each shape should contain an attribute that corresponds to `serviceAreaAttribute`. Only those shapes that correspond to the `selectedServiceArea` will be considered for estimation. The number of shapes for each service area is arbitrary. In any case, each of these waiting time zones gets a unique identifier. The attribute for that identifier is specified in the `waitingTimeZoneAttribute` option.
For the waiting time zones we usually just want some grid-like structure that is covering the service area. For that there is a script in `gis/create_hexagon_grid.py`. It takes a number of command line arguments:
- A path to the shape file containing the actual service areas
- An output path for the new shape file with the waiting time zones
- The name of the attribute that distinguishes between service areas
- The new name of the attribute that distinguishes between waiting time zones
- The horizontal width of the hexagon grid
Example:
```sh
python3 create_hexagon_grid.py path/to/service_areas.shp path/to/waiting_time_zones.shp SAREA WZONE 1000
```
# How to create the partial scenarios
This repository only contains code to run the requested scenarios in the ASTRA 2018/002 project. For the sake of avoiding code duplication, the scenario cutting code is still located in the [baseline_scenario](https://github.com/matsim-eth/baseline_scenario) repository, specifically in the (synpop)[https://github.com/matsim-eth/baseline_scenario/tree/synpop] branch.
