Struct LinkProperties 

pub struct LinkProperties {
    pub free_flow_speed: f64,
    pub capacity: f64,
    pub lanes: u32,
    pub jam_density: f64,
    pub diagram: FundamentalDiagram,
}

Transport-specific physical properties of a link.

This type stores the transport behavior parameters attached to a LinkSpace<LinkProperties> link.

The associated constructors such as LinkProperties::urban, LinkProperties::freeway, and LinkProperties::pedestrian are convenience presets for common real-world link types. They are not a fixed catalog enforced by the engine - users can either use these helpers as starting points or construct/customize values directly.

Fields

free_flow_speed: f64

Free-flow speed in m/s.

capacity: f64

Capacity in units/hour across all lanes.

lanes: u32

Number of lanes or effective parallel channels.

jam_density: f64

Jam density in units/km/lane.

diagram: FundamentalDiagram

Speed-density relationship applied to the link.

Implementations

impl LinkProperties

pub fn urban( length: f64, speed_kmh: f64, lanes: u32, ) -> Result<(LinkGeometry, Self), LinkGeometryError>

Convenience preset for a typical urban road segment.

Returns (LinkGeometry, LinkProperties) so the result can be passed directly into LinkSpace<LinkProperties>::add_link(...).

Arguments:

• length: link length in meters
• speed_kmh: free-flow speed in km/h
• lanes: number of lanes

This is an example/default profile, not a mandatory schema.

pub fn freeway( length: f64, speed_kmh: f64, lanes: u32, ) -> Result<(LinkGeometry, Self), LinkGeometryError>

Convenience preset for a typical freeway segment.

Returns (LinkGeometry, LinkProperties) so the result can be passed directly into LinkSpace<LinkProperties>::add_link(...).

Arguments:

• length: link length in meters
• speed_kmh: free-flow speed in km/h
• lanes: number of lanes

This is an example/default profile, not a mandatory schema.

pub fn pedestrian( length: f64, width: f64, ) -> Result<(LinkGeometry, Self), LinkGeometryError>

Convenience preset for a pedestrian corridor or walkway.

Returns (LinkGeometry, LinkProperties) so the result can be passed directly into LinkSpace<LinkProperties>::add_link(...).

Arguments:

• length: link length in meters
• width: effective corridor width in meters

Width is converted into an approximate number of parallel channels. This is an example/default profile, not a mandatory schema.

Trait Implementations

impl Clone for LinkProperties

fn clone(&self) -> LinkProperties

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LinkProperties

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for LinkProperties

fn eq(&self, other: &LinkProperties) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
