Detailed Description

Data for segments affected by a traffic message.

Speed can be specified in three different ways:

• speed replaces the maximum speed of the segment, if lower
• speed_penalty subtracts the specified amount from the maximum speed of the segment
• speed_factor is the percentage of the maximum speed of the segment to be assumed

Where more than one of these values is set, the lowest speed applies.

Field Documentation

attrs

struct attr** seg_data::attrs

Additional attributes to add to the segments

delay

int seg_data::delay

Expected delay for all segments combined, in 1/10 s

Referenced by seg_data_equals(), and traffic_message_parse_events().

dir

enum location_dir seg_data::dir

Directionality

flags

int seg_data::flags

Access flags (modes of transportation to which the message applies)

Referenced by seg_data_equals(), and traffic_message_parse_events().

speed

int seg_data::speed

The expected speed in km/h (INT_MAX for unlimited, 0 indicates that the road is closed)

Referenced by seg_data_equals(), seg_data_new(), and traffic_message_parse_events().

speed_factor

int seg_data::speed_factor

Expected speed expressed as a percentage of the posted limit (100 for full speed)

Referenced by seg_data_equals(), seg_data_new(), and traffic_message_parse_events().

speed_penalty

int seg_data::speed_penalty

Difference between expected speed and the posted speed limit of the segment (0 for none); the resulting maximum speed is never less than 5 km/h

Referenced by seg_data_equals(), and traffic_message_parse_events().

type

enum item_type seg_data::type

The item type; currently only type_traffic_distortion is supported
