iduedu.TransportSpec¶

class iduedu.TransportSpec(name, vmax_tech_kmh, accel_dist_m, brake_dist_m, traffic_coef=1.0)[source]¶

Configuration of a single public-transport mode used to estimate travel time on graph edges.

Each transport specification defines technical and operational characteristics of a mode (e.g. bus, tram, subway) that are used to compute per-edge travel time based on segment length, road speed limits, acceleration/braking behavior, and traffic conditions.

Parameters:

name (str)
vmax_tech_kmh (float)
accel_dist_m (float)
brake_dist_m (float)
traffic_coef (float)

name¶

Transport type identifier, usually matching the OSM route=* value (e.g. "bus", "tram", "subway").

Type:: str

vmax_tech_kmh¶

Technical maximum speed of the vehicle in kilometers per hour.

Type:: float

accel_dist_m¶

Typical distance (meters) required to accelerate from standstill to cruising speed.

Type:: float

brake_dist_m¶

Typical distance (meters) required to decelerate from cruising speed to standstill.

Type:: float

traffic_coef¶

Traffic slowdown coefficient. Values below 1.0 reduce effective speed due to congestion, values close to 1.0 indicate free-flow or priority operation.

Type:: float

__init__(name, vmax_tech_kmh, accel_dist_m, brake_dist_m, traffic_coef=1.0)¶

Parameters:

name (str)

traffic_coef (float)

Return type:

None
