About this Guide
PASS Schedule Server Switches Reference Guide provides information for different types of switches in Schedule Server.
About Schedule Server
Schedule Server is a server application that facilitates updating, scheduling, and checking of scheduling information in the Trapeze4 Workstation.
Schedule Server switches are settings that can enable, disable, or set limits for scheduling information from Schedule Server.
About Configuring Switches
Schedule Server switches are configured in the Trace Options dialog box accessed through the Schedule Server (SchedSrv) application by clicking View > Switches.
Triangulation Speed Factors requires PASS "triangulation" distance calculation and speed factor calculations to calculate estimated trip times.
About Triangulation
Triangulation is a way of figuring out the distance from three separate locations.
Distance and time speed factors are configured in the Speed Factors screen in the Schedule Administrator application. Speed factors can be defined for weekdays (Monday to Friday) or weekend days (Saturday and Sunday).
Adding Distance-Dependent Speed Factors
You can add a speed factor for distance in Schedule Administrator.
Adding Time-Dependent Speed Factors
You can add the triangulation speed factor.
Modifying Speed Factors
You can modify speed factors in the Speed Factors screen.
Specifying Speed Factors
A speed factor is a number that represents a percentage with which to calculate estimated travel times for events on runs.
About Calculating Trip Costs
All scheduling decisions are performed based on the “cost” of a trip.
The Bad Trip Locator (BTL) is an automated process that finds “bad” trips on runs and moves them to better runs.
Configuring Bad Trip Locator Switches
The Bad Trip Locator (BTL) switches are configuration settings for Bad Trip Locator.
Batch scheduling or batching is the automated process of selecting a bunch of trips.
Configuring Batch Switches
Batch switches are configuration settings for batch scheduling. Batch switches are configured in the Trace Options dialog box of the Schedule Server application.
The PASS scheduling algorithm has been enhanced with capacity type swapping that enables the ability to be used on a run that is more suitable to transport a group of clients.
Configuring CapType Switches
Capacity Type switches are configured in the Trace Options dialog box of the Schedule Server application window.
About the Working of Capacity Type Swapping
Each run has an EligibleForSwapping field in the Run Info step of the Manage Runs screen that indicates whether capacity type (CapType) swapping is allowed to be applied to it. Assigning a vehicle to a run effectively locks its capacity type.
CapType Switches and Descriptions
The following switches are found in the Trace Options dialog box in the Schedule Server application expanding the Switches > PASS > SchedSrv > Cap Type Swapping folder.
Deadhead occurs when you travel in a schedule or run itinerary from one event or location to another during which there are no passengers on board the vehicle (for example, a garage to a pick-up location, or from a drop-off location to the next pick-up location); therefore, no revenue is generated during such periods.
Configuring Deadhead Switches
Deadhead switches are configured in the Trace Options dialog box of the Schedule Server application window.
About Deadhead Cost Calculation
Deadhead calculations are used to help determine how desirable a trip solution is when searching for scheduling solutions. The selected formula is applied only to an event with deadhead time before it, and the sum of these calculations determines the total deadhead cost for an entire run for the day.
About Deadhead Calculation Formulas
There are four formulas that Schedule Server can use to calculate trip costs for deadhead:
Deadhead Switches and Descriptions
The following switches are found in the Trace Options dialog box in the Schedule Server application by expanding the Switches > PASS > SchedSrv > Deadhead folder:
Fast Costing is performed by the Schedule Server to quickly evaluate a group of candidate solutions and select the best ones to present to the user when scheduling a client trip.
Configuring Fast Costing Switches
Fast Costing switches are configured in the Trace Options dialog box of the Schedule Server application window.
Performing Fast Costing
When Schedule Server performs Fast Costing on a candidate solution, it performs the following procedure:
FastCost Switches and Descriptions
The following switches are found in the Trace Options dialog box in the Schedule Server application expanding the Switches > PASS > SchedSrv > Deadhead folder.
Backtracking occurs when a vehicle with a passenger on board returns to or close to a location where the passenger was picked up, or passes by a destination area and leaves without dropping off the client, resulting in a Backtracking violation (BT).
Configuring Backtracking Switches
Backtracking switches are configured in the Trace Options dialog box of the Schedule Server application window.
About the Working of Backtracking
Backtracking is checked for every booking between its origin and destination. BT violations are calculated and considered only if the Use Angular Backtrack Check switch is enabled.
Backtracking Switches and Descriptions
The following switches are found in the Trace Options dialog box in the Schedule Server application expanding the Switches > PASS > SchedSrv > Violations > Backtracking folder.
