A permanent object is created with a reference count of one, so it is not deleted when the driver dereferences it. A driver can only delete a permanent object it created by using the ZwMakeTemporaryObject routine to make it temporary. Use the following steps to delete a permanent object that you created: Call ObDereferenceObject. If the driver has a driver's license from any nation except Canada, they must pass a written test, complete a 5-hour pre-licensing course, and pass a road test to qualify for a driver's license. 85 Texas does not require drivers from Canada, France, Germany, or Taiwan to take the written and practical tests, but drivers must agree to a vision.

PTV Vissim is a microscopic multi-modal traffic flow simulation software package developed by PTV Planung Transport Verkehr AG in Karlsruhe, Germany. The name is derived from 'Verkehr In Städten - SIMulationsmodell' (German for 'Traffic in cities - simulation model'). PTV Vissim was first developed in 1992 and is today a global market leader.
Scope of application[edit]
The scope of application ranges from various issues of traffic engineering (transport engineering,[1]transportation planning, signal timing), public transport, urban planning over fire protection (evacuation simulation) to 3d visualization (computer animation, architectural animation) for illustrative purpose and communication to the general public.
PTV Vissim is part of the PTV Vision Traffic Suite which also includes PTV Visum (traffic analysis and forecasting) and PTV Vistro (signal optimisation and traffic impact).
Modelling[edit]
Microscopic simulation[edit]
The basic traffic model ruling the movement of vehicles was developed by Rainer Wiedemann in 1974 at Karlsruhe University.[2] It is a car-following model that considers physical and psychological aspects of the drivers.
The model underlying pedestrian dynamics is the Social Force Model by Dirk Helbing et al. from 1995.[3]
'Microscopic simulation', sometimes called microsimulation, means each entity (car, train, person) of reality is simulated individually, i.e. it is represented by a corresponding entity in the simulation, thereby considering all relevant properties. The same holds for the interactions between the entities. The opposite would be a 'macroscopic simulation', in which the description of reality is shifted from individuals to 'averaged' variables like flow and density. The corresponding product from the same manufacturer is called Visum.
Transport modes[edit]
In Vissim the following types of traffic can be simulated, and mutually interact:
- Vehicles (cars, buses, and trucks)
- Public transport (trams, buses)
- Cycles (bicycles, motorcycles)
Vehicle interactions[edit]
In VISSIM, vehicle conflict points can be modelled using Priority Rules, Conflict Areas[4] or Signal Heads.[5]
Signals can be modelled with fixed-time plans, or various modules such as VAP (Vehicle Actuated Programming) are available to model on-demand signals and other types of control and coordination.
Versions and associated files[edit]
Versions up to 5.40 created .INP files which used a proprietary language. Versions 6 and later created .INPX files which use an XML-based language. Both produce human-readable code:

This document details how to upload drivers into SCCM, create driver packages and keep everything organised.
Driver packages in SCCM 2012 are used for installing device drivers. Drivers uploaded into SCCM can be bundled together into a single package for a specific device. Driver packages are most commonly installed through a task sequence whilst building a new computer.
30 Steps total
Step 1: Preparation
Before creating a driver package you must first upload all the drivers that you need to the configuration manager content source location. In this example ours is servercm-sources.
Create two folders on the share where you keep configuration manager content – one called ‘Drivers’ and one called ‘Driver_Packages’. The drivers folder will be where we upload drivers to and the driver packages folder is where SCCM will store content for driver packages. You should not manually upload anything into the driver packages folder.
Step 2: Create subfolders for different Manufacturers and Models in Drivers and Driver_Packages
You should keep all device drivers organised by manufacturer. You should then create sub folders within these folders for each model.
In this example I am going to upload drivers for a Dell E7240. Therefore my folder structures looks like this:
Servercm-sourcesDriversDellE7240
Servercm-sourcesDriver_PackagesDellE7240
Step 3: Download the relevant device drivers directly from the Manufacturer
In this case we have downloaded the drivers from the Dell website.
Step 4: Copy the drivers into the drivers folder
In this case we have copied the drivers to Servercm-sourcesDriversDellE7240. Do not copy them into the driver packages folder.
Step 5: Open Configuration Manager Console
Navigate to Software Library > Operating Systems > Drivers
Step 6: Create a folder for the manufacturer
Right click drivers and click Folder > Create Folder.
In this case we are going to call the folder ‘Dell’.
Step 7: Create a subfolder within the manufacturer folder for the model
Right click the manufacturer folder, click Folder > Create folder
In this case we are going to call the subfolder ‘E7240’.
Step 8: Uploading drivers and creating a driver package
Right click Drivers and click Import Driver.
Step 9: Select Import all drivers in the following network path (UNC)
Enter the UNC path for ServerCM-SourcesDriversManufacturerModel. In our case the UNC path is ServerCM-SourcesDriversDellE7240.
Step 10: Click Next.
Drivers Created By Y.k Serial
Step 11: Assign the drivers to a category
Check the box for ‘Enable these drivers and allow computers to install them’ and then click Categories > Create and enter a name (e.g. Manufacturer and Model). In this case we have named the category Dell E7240
Step 12: Ensure the new category is checked and click OK and then Next.
Step 13: Click New Package and enter the details for the new package
Ensure‘Update distribution points when finished is’ checked and then click New Package.
Step 14: Name the driver package and enter the UNC path where you want Configuration Manager to store drivers added to the package
We are using the naming convention [Manufacturer] [Model] Driver Package.
This time the UNC path will be for the model folder you created in the Driver_Packages folder. In this example our UNC path is SERVERCMSourcesDriver_PackagesDellE7240.
Click OK.
Step 15: Ensure the new package is checked and click next.
Step 16: Do not select any boot images and click next.
Step 17: Click next on the summary window and then wait for the drivers to import.
Step 18: Review any failed driver imports and then click close.
Step 19: Move drivers and driver packages into folders
We now want to move the drivers into the correct folder to keep everything organised.
Drivers Created By Y.k Vin
Click on Drivers and then Categories to sort all drivers by categories.
Step 20: Select all the Drivers that need to be moved.
In this case we are selecting every driver assigned to the Dell E7240 category.
Step 21: Right click the selected drivers and click move.
Step 22: Select the folder for the model and then click OK.
Step 23: We now want to move the newly created driver package.
Drivers Created By Y.k C.
Click on Driver Packages in SCCM.
Step 24: You will see the newly created driver package here.
Step 25: Right click Driver Packages and click Folder > Create Folder
Step 26: Create a folder for the manufacturer – In this case we have named it Dell.
In this case we have named it Dell.
Step 27: Create a sub folder for the model
Right click the manufacturer folder and click Folder > Create Folder.
Step 28: Click on Driver Packages, right click the driver package which needs to be moved and click move.
Step 29: Select the folder for the model and click OK.
Step 30: The driver package will now be in the Driver Packages > Manufacturer > Model folder.
We have now uploaded drivers, created a driver package and organised everything so that it is easy to find.
