TRANSIMS Version 5Program Controls

January 20, 2011David Roden – AECOM

Chicago RTSTEP TRANSIMS Model2

Topics Goals and objectives Key program changes

– NetPrep– TransimsNet– Router– PathSkim– PlanPrep– SimSubarea– Microsimulator

1/20/2011


Goals and Objectives Refinements based on user-feedback Make key names more user-friendly and obvious

– Clearly distinguish input and output files– The print file always writes the text of the key name– Simple group keys keys with multiple fields

Programs with common key names have the same meaning and behavior

Reduce documentation lookup for new users Project-specific or user-specific global control keys

Spatial Refinements Keep/Delete Elements


NetPrep – New Concepts Local-Thru segment length

– Assigns local streets to the new Local-Thru facility type based on the length of a series of local links

Local selection spacing– Selects representative local streets from an all-streets network for

inclusion in the TRANSIMS network

Drop dead end and short links– Links less than length value are dropped

Split large loops– Loops (anode=bnode) will be split into two links to permit loading

1/20/2011


Collapse Divided Arterials GIS often includes parallel links for divided arterials Complicates TRANSIMS coding and simulation of

signalized intersections– Version 5 can model multi-node signals, but the network will be easier

to edit and the simulate if a single node is used• The DIVIDED field in the link file models link access like parallel roadways

1/20/2011


New Group Concepts LOCAL_SELECTION_SPACING_*

– * is the first area type value in the list• It is optional, defaults to 1• Supports up to 100 area types

Application options– LOCAL_SELECTION_SPACING = 100, 200, 300, 400– LOCAL_SELECTION_SPACING_1 = 100, 200, 300, 400– LOCAL_SELECTION_SPACING_2 = 200– LOCAL_SELECTION_SPACING_10 = 1000, 1100, 1200

• Result = 100, 200, 300, 400, 400, 400, 400, 400, 400, 1000, 1100, 1200

1/20/2011


TransimsNet Network node and link selecting and collapsing

moved to NetPrep Primary function is to synthesize additional data

required for dynamic network modeling– Pocket lanes, link connections, activity locations, parking lots, and

traffic control warrants

Includes much finer control over the synthetic data generation logic– Pocket lane, facility access, and traffic control warrants– Adds parking lot processing time and cost by time of day

Router

Version 4 Router Router and PathSkim– Router build travel plans from a trip file– PathSkim build travel skims from a user-specified O-D-T list

• Replaces Router PlanSum process

Version 5 path building is a SysLib service– Path Builder classes support multiple threads and DLL integration with

other software– Also supports on-the-fly path building within the Microsimulator

1/20/2011


Version 5 Router New features

– Forward and backward paths based on time constraints– Builds paths with or without access links– Uses impedance sorting to minimize transit transfer problems– Models parking time and cost by time of day– Lane use rather than link use restrictions

• Includes tolls and random processing rates (toll plaza, security gate, etc.)– Uses consistent mode codes for all TRANSIMS modules– Outputs link-based plans for complete trips

• No traveler scaling, link vs. node files, walk-leg-only trip problems– Cumulates flows and updates link delay files– Updates existing plan records with latest link delays

PathSkim Specifies a set of origin-destination-times-mode for

one-to-many path building and skimming– Multiple methods for selecting OD locations within zones

• Random, centroid, distribute– Location, zone or district-based skims

Microsimulator New design

– Vehicle processing is split into geographic subareas for multi-core processing (threads or MPI)

– Each subarea can be modeled at a different level of detail• None, macro, meso, micro• Version 4 cellular automata meso scale

– Multi-node signal coordination and vehicle detection– Multiple traveler types with different simulation sensitivities– Inherits from Router services to enable on-the-fly re-routing

• Wait time problems can trigger route adjustments– Integrated multi-modal trip plans

• Critical for coordinating transit trip legs
