Road Pack Configuration

Scroll Prev Top Next More

Press the Edit Config button on the main Ultra Pre-Processor's main dialog box to set the configuration settings for the new road pack. This displays the Configuration dialog box:




The list in the middle, lists the different road types in the input road data and their road speeds. Other settings allow you to set a description for the road pack, set the default road speed units, and the route types to optimize for.


There are quite a few things to set. You can initialize the settings from an existing UMG road pack by pressing the Load Config button. Alternatively, you can load just the road speed definitions from a UMG road pack file by pressing the Load Speeds button.


A Description can be added to the road pack. This is displayed in Ultra MileCharter or Ultra One2OneMileage when you select the road pack. This is for your own reference, so you can enter whatever information you wish.


Pre-processing optimizes the road network for the specified road speeds and route types. Use the Route Types box to choose the type of route to optimize for. Fastest Routes will optimize for the shortest travel time; whilst Shortest Routes will optimize for the shortest distances.


The road speeds are displayed using the specified Road Speed Units. A range of units are supported although most users will typically use Miles or Kilometers. The choice of units does not affect the optimization, and only specifies how you would like the speeds to be displayed. You can select a different distance unit in Ultra MileCharter or Ultra One2OneMileage if you wish.


Each road type is listed in the list of road speeds. These are the road types used in the OpenStreetMap data, and follow standard OpenStreetMap conventions. The Pre-Processor will ignore all road types that are not in this list.


To change a road's speed, click on the road type's Speed cell, and then enter a new speed. You can also change a road type's name by clicking on the name and editing it.


You can tell the Pre-Processor to ignore a specific road type by clearing the check box in the Enabled column.


For example, the following configuration will ignore all roads marked as bus_guideway, raceway, pedestrian, footway, bridleway, or steps :




By changing these selections, you could create a road pack for cyclists or pedestrians instead of cars and other road vehicles.


You can add a new road type by pressing the Add Road button. This will create a new road with a default name of "new road type" with a speed of 30mph. Edit these to your required settings.


A road type can also be deleted. Do this by selecting the entire road type row (click on the gray rectangle on the far left of the row), and press the Delete key.


Some roads are marked in the OpenStreetMap database with minspeed and/or maxspeed tags. You can tell the Ultra Pre-Processor to either use these or ignore them. These work as min/max range limits. For example, if you have defined a road type to have a speed of 70mph, but a section of that road has a maxspeed of 55mph, then Ultra Pre-Processor will use the 55mph speed. The Use Min/Max Speed Limits (if defined) check box is used to switch these limits on (the default) or off.


The Optimization box includes a number of settings for road pack optimization and filtering. These are explained in further detail on the Road Pack Optimization Options page.


After all settings have been edited, press OK to save them and return back to the main Pre-Processor dialog box.
