12. Interchange Coding

13. Interchange Coding, Another Example

14. 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.

15. Interchange Coding, CD

16. 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).

17. Interchange Coding, braided ramps

18. 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.

19. 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

30. ARC-Coded ITS Strategies for Future Network Years (2030) 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

31. 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)

32. 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

33. 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
