A deadhead is a distance a revenue-gaining vehicle makes without carrying any passengers.
For example, the distance it makes from the depot to its first trip of the day is considered a deadhead.
The deadhead catalog stores the travel times between all stops. During optimization, the catalog is used to determine the best way to link trips. In this article, you will learn how to view the deadhead catalog, how it is structured and used.
Downloading the deadhead catalog
You can view your project’s deadhead catalog in two ways: by downloading through the side menu or through the Preferences menu.
Side panel
To download your catalog through the side panel, follow these steps:
Open the side panel by clicking the hamburger icon in the top-left corner of the screen:
Click Catalogs.
Click on the catalog you want to download.
Click Download.
Preferences
To download the deadhead catalog through the Preferences menu, follow these steps:
While in Planning or Scheduling, open Preferences:
Find and click Deadhead Catalog in the MISC section.
The preference will display the catalog currently used by the project. To download it, click the Ct button, then click Download.
Structure
Column | Description | Notes | Input example |
Origin Stop Id/Destination Stop Id | The IDs of stops between which the deadhead exists. |
| 1027 |
Travel Time | The time it takes to get from the origin stop to the destination stop (in minutes) |
| 3 |
Distance | The distance between the origin and destination stops |
| 12.2 |
Start Time Range/End Time Range | The time range where the deadhead applies. This can be used to create multiple instances of a deadhead where travel time varies throughout the day | In pull-outs, the time range of the arrival time defines the applied deadhead. In pull-ins, it’s the range that the starting time falls into. | 02:07 |
Origin Stop Name/Destination Stop Name | The names of stops between which the deadhead exists. |
| Quickborner Str. |
Days Of Week | The days the deadhead applies to, specified as numbers. | 1 is Sunday, 23456 is Monday to Friday and 7 is Saturday. If the cell is left blank for the deadhead, it applies to all days of the week. | 2345 |
Direction | Not relevant |

Purpose | Not relevant |

|
Alignment | Whether the deadhead should be added immediately after the trip or the latest after. | The input must be either earliest or latest | earliest |
Pre-Layover Time/Post-Layover Time | How much buffer time (in minutes) is added before or after the deadhead. | See examples of different buffer time configurations in the note below the table | 5 |
Note:
Here is how layovers or lack thereof would look in the Gantt view:
No pre-layover:
Pre-layover of 5 min:
No post-layover (first trip of the block):
Post-layover of 5 min:
Managing deadhead catalogs
You can update or replace your deadhead catalog.
If you want to modify some deadheads and add new ones without deleting the existing ones, you can update the catalog.
If you want to change the catalog completely, including deletion of stops, you can go with the Replace option.
To update or replace your catalog, follow these steps:
Find the catalog as described in the Downloading catalogs paragraph.
If needed, download the current catalog and make the necessary changes in it.
Click the Replace or Update button and select the updated or new catalog.
Click Open.
