  1. TRANSIMS Version 5Program Controls January 20, 2011 David Roden – AECOM

  2. Topics • Goals and objectives • Key program changes • NetPrep • TransimsNet • Router • PathSkim • PlanPrep • SimSubarea • Microsimulator Chicago RTSTEP TRANSIMS Model

  3. 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 Chicago RTSTEP TRANSIMS Model

  4. NetPrep (new program) • Key Features • Combines GISNet, TPPlusNet, and EMME2Net features • Performs TransimsNet functions related to link and node selection • New spatial network manipulation controls • Merge networks • User-scripts supported • Can be run iteratively Chicago RTSTEP TRANSIMS Model

  5. NetPrep Control Keys NetPrep Merge Networks Spatial Refinements Keep/Delete Elements LINK_FILE INPUT_LINK_FILE NODE_FILE INPUT_NODE_FILE ZONE_FILE INPUT_ZONE_FILE SHAPE_FILE INPUT_SPDCAP_FILE INPUT_UNITS_OF_MEASURE FACILITY_INDEX_FIELD AREA_TYPE_INDEX_FIELD CONVERSION_SCRIPT INTERNAL_ZONE_RANGE SPEED_FACTOR_BY_FACILITY SPEED_ROUNDING_INCREMENT MAXIMUM_LENGTH_TO_XY_RATIO MAXIMUM_SHAPE_ANGLE MINIMUM_SHAPE_LENGTH DROP_DEAD_END_LINKS DROP_SHORT_LINKS SPLIT_LARGE_LOOPS COLLAPSE_SHAPE_NODES COLLAPSE_DIVIDED_ARTERIALS LOCAL_THRU_SEGMENT_LENGTHS_* LOCAL_SELECTION_SPACING_* KEEP_NODE_RANGE KEEP_NODE_FILE KEEP_LINK_RANGE KEEP_LINK_FILE DELETE_NODE_RANGE DELETE_NODE_FILE DELETE_LINK_RANGE DELETE_LINK_FILE Chicago RTSTEP TRANSIMS Model

  6. 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 Chicago RTSTEP TRANSIMS Model

  7. 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  Chicago RTSTEP TRANSIMS Model

  8. 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 Chicago RTSTEP TRANSIMS Model

  9. 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 Chicago RTSTEP TRANSIMS Model
