Traffic Operations (TOS)

TOS	Definition
0	Freeway is not managed with ramp metering infrastructure
1	Freeway is managed with ramp metering infrastructure
2	Freeway is managed with ramp metering and other (tbd) infrastructure. Note that setting this does not trigger anything, but setting FT=8 will automatically set this in set_capclass.job

SIGCOR	Definition
0	Signals on the roadway segment are not coordinated
1	Signals on the roadway segment are coordinated

Vehicle Restrictions (USE)

USE	Definition
1	All vehicles may use the roadway

3	High-occupancy vehicle (HOV) lane with a minimum of three persons per vehicle; combination trucks prohibited
4	Combination trucks prohibited (used for Express Lanes)

Toll Code (TOLLCLASS)

7	Code specific to the Dumbarton Bridge	1927	2015 Base
8	Code specific to the Antioch Bridge	1978	2015 Base
9	Code specific to the Treasure Island Congestion Pricing. See detail on cordon toll implementation in Implement means-based cordon discounts (for tolls and transit fares)	2035	SF_110049_Treasure_Island_Congestion_Pricing
10	Code specific to the San Francisco Congestion Pricing (Cordon Toll). See detail on cordon toll implementation in Implement means-based cordon discounts (for tolls and transit fares)	2025	SF_130017_SF_Congestion_Pricing
11	Code specific to Oakland Congestion Pricing (Cordon Toll)	N/A	NGFS
12	Code specific to San Jose Congestion Pricing (Cordon Toll)	N/A	NGFS
31 and higher	Codes specific to "value tolls" which can only be assessed for tolled paths in mode choice (e.g. they are not allowed for free paths )
231	SR-237 Express Lanes Phase 1 - SR237 - US101 Interchange to I-880 Interchange - EB	Mar 2012	2015 Base
232	SR-237 Express Lanes Phase 1 - SR237 - US101 Interchange to I-880 Interchange - WB	Mar 2012	2015 Base
690	I-680 Sunol Express Lane - I-680 ALA - SCL County Line to SR84 - SB	Sep 2010	2015 Base
887	SR-237 Express Lanes Phase 1 - I-880 SCL - SR237 to SR262 Mission Blvd - NB (last segment after TOLLCLASS 231)	Mar 2012	2015 Base
888	SR-237 Express Lanes Phase 1 - I-880 SCL - SR237 to SR262 Mission Blvd - SB (first segment before TOLLCLASS 232)	Mar 2012	2015 Base

Facility Type (FT)

FT	Definition
1	Freeway-to-freeway connector
2	Freeway
3	Expressway
4	Collector
5	Freeway ramp
6	Dummy link
7	Major arterial
8	ITS-managed Freeway (not relevant to pricing or tolling)
9	Special facility
10	Toll plaza

Area Type (AT)

The formula is as follows:  (total population + 2.5 * total employment) / (developed residential acres + developed commercial acres)

AT	Label	Range
0	Regional core	> 300
1	Central business district	100 to 300
2	Urban business	55 to 100
3	Urban	30 to 55
4	Suburban	6 to 30
5	Rural	< 6
6	Not an area type, this is added to enable a special capclass 62 for I280 in TM1.5	NA

Capacity Class (CAPCLASS)

CAPCLASS determines the capacity (CAP), free flow speed (FFS), and critical speed (CritSpd) of the link.

CAPCLASS itself is determined by the following factors:

• Area Type (AT)
• Facility Type (FT)
• Traffic Operations (TOS)
• Signal Coordination (SIGCOR)
• Route Number (ROUTENUM)

In the script set_capclass.job, CAPCLASS is calculated using the formula: CAPCLASS = (AT * 10) + FT. However, overrides apply when:

• the freeway is managed with ramp metering infrastructure i.e. Traffic Operations (TOS) = 1, or
• signals on the roadway segment are coordinated i.e. Signal Coordination (SIGCOR) = 1, or
• the link is part of the I-280 freeway i.e. Route Number (ROUTENUM) = 280 (to enable a special setting for the free flow speed on I-280, which was observed to have a higher free flow speed than other freeways in the region)

The spreadsheet Capclass_Speed_Capacity.xlsx illustrates how CAPCLASS is calculated in set_capclass.job.

The relationships between CAPCLASS, capacity (CAP), and free flow speed (FFS) are specified in set_capclass.job. The relationship between CAPCLASS and critical speed (CritSpd) is defined in FreeFlowSpeed.block.

 

Bus Rapid Transit (BRT)

BRT	Definition
0	Roadway segment does not include a dedicated bus lane with full BRT treatments
1	Roadway segment includes a dedicated bus lane with full BRT treatments
2	Roadway segment includes reduced bus delays (e.g. transit signal priority)
3	Roadway segment (freeway) allows for buses to travel on the shoulder

The BRT attribute is used in PrepHwyNet.job
