ARC Highway Networks & Related TAZ Geometrics
• Expanded Zonal Structure from 948 internal TAZ
to 1683, maintained External Stations to 57
zones, for a grand total of 1740 TAZ, compared
to 1005 previously
• QA/QC 2000 Base Year Highway Network using
GIS-T techniques and Aerial Photography
• Revisited Centroid Connectors to accommodate
new internal TAZ geometric reconfiguration
• Refined Facility Types Definitions using ARC
CMS Strategic Arterial System Definitions
• Updated Free-Flow Speeds and Capacities
Look-Up Tables, based upon 2000-2001 travel
times and speed studies
Principles of ARC Highway Network Coding
Difference between:
the “real-world” curvilinear shape of roads/streets, such as
from GDOT’s DLGF (Digital Linear Graphic Format)
and
a “stick” highway network coded in TP+ / Viper

Interchange Coding
Interchange Coding, Another Example
Collector Distributor Roadway
•
•
•
•
A one-way road parallel to the main traffic lanes
Provides access to / from more than one ramp
Collects traffic from on-ramps or the main lanes
Distributes traffic to off-ramps or back to the
main lanes
• Minimizes interactions with thru traffic
• Serves closely spaced interchanges.
Interchange Coding, CD
Braided Ramps
• Used where hypothetically 2 nearly parallel ramps must
cross each other and use a grade separation to avoid
weaving
• Where the on-ramp from one nearby interchange is
braided to avoid interfering with the off-ramp for the next
one
• Eliminates non-acceptable weaves
• Are structures designed to separate traffic using the
same stretch of road for competing purposes
• Alleviates competition between cars trying to enter and
exit by separating each movement to a different roadway
(i.e. split diamond with braids).
Interchange Coding, braided ramps
Transition Tapers, Auxiliary Lanes,
Acceleration and Deceleration Lanes
• These are perceived as pavement
transitions.
• Transitions for lane additions, either for left
or right turns or to add a lane to a ramp,
should occur over a length of at least ¼
mile (1,320 feet) in order to warrant
detailed coding attention from the ARC
• Could be considered adding capacity,
depending upon length.
Log Files for
Network Coding Management
• Record activity in an ASCII text file which
is then saved and played later on
networks.
• Because they are based upon the base
network, logs contain same data fields and
restrictions as the network itself.
• Each highway project has its own log file,
hence facilitating coding efforts and
management of scenarios

Advanced Traffic Signal Coordination and Control
Fiber-optic Communications
Video Surveillance and Data Collection on Entire Corridors
Activity Center Surveillance at Interstate Highway Crossings, Industrial
Yards, Shopping Malls, Cross Regional Corridors
Facilities Parallel to Interstate Highways
Variable Message Signs (VMS) at Major Decision Points on Freeways
Transit Vehicle Signal Priority
Automated Vehicle Location (AVL) for Transit
Electronic Fare Payment for Transit Service
Queue Jumper Lanes for Transit
Ramp Metering on Freeways
ITS benefits expressed in terms of:
• travel time savings
• delay reductions
• free-flow speeds increases
• localized transit mode share increases
Highway ITS Strategies for Coding Future
Network Years (2030), not used for air quality
conformity determination, just a test for
aspiration plan, not the constrained plan
Highway Capacity Improvement:
Add Variable to Coded Highway Network:
Freeway capacity * 1.08 (6% increase for
surveillance & detection, 2% increase for
dynamic message signs)
Arterial capacity * 1.03 (3% increase for
surveillance & detection)
Highway Speed Improvement:
Signal system benefits only for arterials &
collectors.
Benefits apply to all ITS packages, level of benefit
dependant upon area type with higher densities
receiving greater benefits.)
CBD: speed * 1.08
High Density Urban: speed * 1.07
Medium Density Urban: speed * 1.06
Medium Density Suburban: speed * 1.05
Low Density Suburban: speed * 1.04
Exurban: speed * 1.03
Rural: speed * 1.02
ARC’s Transit Network Coding
• Developed a Bus Speed Model
– Empirical model to hook bus speeds with congested highway travel
times, reflecting mixed flow of traffic operating conditions
• Defined 3 types of transit service access
– Walk to local bus service
– Walk to premium (with local bus & rail)
– Drive to transit
• Separated walk to local from walk to premium
• Automated procedures for walk-to-transit links, with maximum length
based on area of zone
• Separated Park-And-Ride (PNR) lots by types, local VS premium
– Local, max access time = 15 minutes
– Premium, max access time = 60 minutes
• Created procedures to build drive to premium PNR lots to focus on
appropriate market, minimizing illogical paths. Maximum access
time increases as market direction is approached
• Refined mode-to-mode transfer prohibitions, improving transit paths
• Improved Bus Rapid Transit (BRT) coding methods
