OKI Network Consolidated model with Dayton MPO. 3200 network road miles in OKI portion (5400 total). 54 mil DVMT (OKI) ~ 1600 zones and 12000 links (OKI) 308 bus lines (OKI) No passenger rail in base year network.

Consolidated model with Dayton MPO.

3200 network road miles in OKI portion (5400 total).

54 mil DVMT (OKI)

~ 1600 zones and 12000 links (OKI)

308 bus lines (OKI)

No passenger rail in base year network.

Build Model/GIS Relationship One-to-one relationship between all highway links and GIS street centerline. Added 3 fields to street centerline: from node, to node, sequence. Moved highway network nodes to match street centerline.

Added 3 fields to street centerline: from node, to node, sequence.

Moved highway network nodes to match street centerline.

Transit Network Changes made in conjunction with highway network. Script to convert transit lines to shapefile. Text file to shape

Changes made in conjunction with highway network.

Script to convert transit lines to shapefile.

Text file to shape

Benefits No major development/redesign needed True shape display. Ability to transfer data between the Model and GIS. Modify Network and Street Centerline in one place. Eases development of simulation network (prepare for export to Dynasim)

Use of GIS data in Simulation GIS data used for: Splitting zones Modifying “stick” network to match shape Within Dynasim, use aerial photos to correct geometry, add turn lanes. GPS data used for bus stops and parking restrictions. 2d and 3d background development: Aerial photos, building footprints, edge of pavement, street labels.

2d and 3d background development:

Aerial photos, building footprints, edge of pavement, street labels.

Why use simulation? Traditional regional travel demand model is not sensitive to local improvements such as: signalization new intersection turn lanes Integration of pedestrians and transit Improved geometry Decision-makers can visualize impact; supports charts, graphs, LOS plots

Simulation Development Goals Integrate with current travel demand model and GIS data Most work done in-house; utilize skills of OKI staff Use as an outreach tool in support of OKI’s Corridor Studies or to assist member communities.

Sub-Area Model Extract sub-area and peak period trip table from regional model Refine sub-area by disaggregating zones and adding links (local streets). Distribute zonal vehicle trips to subzonal vehicle trip table. Run sub-area vehicle assignment. Export to Dynasim
