1//! Traffic-flow semantics for `rustsim`.
2//!
3//! This crate provides link-level traffic-flow types (fundamental diagrams,
4//! signal timing, turn/control semantics, link properties) that sit above
5//! `rustsim-core` and `rustsim-spaces`, and can be used by multimodal
6//! simulations without pushing traffic-specific concepts into the engine
7//! core.
8//!
9//! Included concepts:
10//!
11//! - transport link/network semantics layered on top of
12//!   [`rustsim_modes::TravelMode`] and [`rustsim_modes::AllowedModes`]
13//! - [`TrafficControlType`] - signal/stop/yield/uncontrolled controls
14//! - [`TurnType`] - directional turn semantics at intersections
15//! - [`LinkClass`] - coarse transport link classification
16//! - [`FundamentalDiagram`] and [`LinkProperties`] - transport link behavior
17//! - [`TransportLinkOps`] - transport operations over generic `LinkSpace<LinkProperties>`
18//! - [`policy`] - explicit queue and control policy contracts
19//! - [`TransportLinkMetadata`] - minimal reusable link semantics
20//! - [`TransitStopMetadata`] - minimal reusable transit stop semantics
21//! - [`signal`] - signal phase timing engine
22//! - [`pedestrian_links`] - Weidmann 1993 pedestrian FD and pedestrian link properties
