dict with a bridge_key that ranges from 1 to 1889 and then the value is another dictionary with the following keys:
loren_row_number: the row number in Loren Turner's table that has info on all CA bridges (where the header line is row 0)
original_id: the original id (1-1889)
new_id: the new id that excludes filtered out bridges (1-1743). Bridges are filtered out if a.) no seismic capacity data AND non-transbay bridge or b.) not located by Jessica (no edge list). this id is the new value that is the column number for the lnsa simulations.
jessica_id: the id number jessica used. it's also the number in arcgis.
a_b_pairs_direct: list of (a,b) tuples that would be directly impacted by bridge damage (bridge is carrying these roads)
a_b_pairs_indirect: ditto but roads under the indirectly impacted bridges
edge_ids_direct: edge object IDS for edges that would be directly impacted by bridge damage
edge_ids_indirect: ditto but roads under the indirectly impacted bridges
mod_lnSa: median lnSa for the moderate damage state. the dispersion (beta) for the lognormal distribution is 0.6. (See hazus/mceer method)
ext_lnSa: median lnSa for the extensive damage state. the dispersion (beta) for the lognormal distribution is 0.6. (See hazus/mceer method)

dict where the keyranges from 1 to 1889 and then the value is another dictionary with the following keys:
loren_row_number: the row number in the original table that has info on all CA bridges (where the header line is row 0)
original_id: the original id (1-1889)
new_id: the new id that excludes filtered out bridges (1-1743). Bridges are filtered out if a.) no seismic capacity data AND non-transbay bridge or b.) not located by Jessica (no edge list). this id is the new value that is the column number for the lnsa simulations.
jessica_id: the id number jessica used. it's also the number in arcgis.
a_b_pairs_direct: list of (a,b) tuples that would be directly impacted by bridge damage (bridge is carrying these roads)
a_b_pairs_indirect: ditto but roads under the indirectly impacted bridges
edge_ids_direct: edge object IDS for edges that would be directly impacted by bridge damage
edge_ids_indirect: ditto but roads under the indirectly impacted bridges
mod_lnSa: median Sa for the moderate damage state. the dispersion (beta) for the lognormal distribution is 0.6. (See hazus/mceer method)
ext_lnSa: median Sa for the extensive damage state. the dispersion (beta) for the lognormal distribution is 0.6. (See hazus/mceer method)
com_lnSa: median Sa for the complete damage state. the dispersion (beta) for the lognormal distribution is 0.6. (See hazus/mceer method)
