2.4.1.3. Transportation Network Source File Option 1

A JSON file containing highway transportation roadways, bridges, and tunnels for the response simulation and damage/loss estimation steps of the workflow. This file contains all the information necessary for constructing AIM files for each bridge, tunnel, and roadway. The JSON file must contain the “nodes” object and at least one of the “hwy_bridges”, “hwy_tunnels”, and “roadways” objects. Involved key-item pairs are:

• “hwy_bridges”: A JSON array of JSON Objects, each containing the following key/item pairs

	Earthquake Required	Earthquake Required	Earthquake Required	Earthquake Required	Basic	Basic	Basic	*OptionalInputs
Key	ID	location	bridge_class	year_built	state_code	nspans	lmaxspan
Item	A string of the bridge ID.	An integer of the ID of the node that describes the location of the bridge.	A three-digit integer describes the bridge class as defined in the HAZUS Inventory Technical Manual (FEMA 2022).	A four-digit interger describes the built year of the bridge.	A two-digit string of the FIPS Code of the state that the bridge is located in.	An integer describes the number of spans, as defined in the HAZUS Inventory Technical Manual (FEMA 2022).	A floating point number describes the length of the longest span of the bridge, as defined in the HAZUS Inventory Technical Manual (FEMA 2022).	(Optional) Additional items which may be included for custom bridge definitions.
Example	“ID”: “330086”	“location”: 6	“bridge_class”: 316	“year_built”: 1953	“state_code”: “06”	“nspans”: 1	“lmaxspan”: 31.9

• “hwy_tunnels”: A JSON array of JSON Objects, each containing the following key/item pairs

	Earthquake Required	Earthquake Required	Earthquake Required	*OptionalInputs
Key	ID	location	cons_type
Item	A string of the tunnel ID.	An integer of the ID of the node that describes the location of the tunnel.	A string describes the construction type as defined in HAZUS Earthquake Model Technical Manual (FEMA 2022). Values allowed are ‘Bored’, ‘Cut’, or ‘unclassified’.	(Optional) Additional items which may be included for custom tunnel definitions.
Example	“ID”: “330106L”	“location”: 8	“cons_type”: “unclassified”
