Data and standards
Gouvernance des données
Data governance is the allocation of responsibilities and rules for creating, maintaining, using, and sharing data. In curb programs, governance connects legal records, operational observations, privacy controls, and public information, identifying who approves changes, resolves conflicts, grants access, and remains accountable when data affects real street access.
Data and standards
Interopérabilité des données
Data interoperability is the ability of systems to exchange information and use it with consistent meaning. For curb management, interoperability involves identifiers, locations, time conventions, activity categories, permissions, and versions, so matching file formats alone does not ensure that two organizations interpret a curb rule in the same way.
Sensing and privacy
Latence des données
Data latency is the delay between an event or observation and the time its information becomes available for use. Curb information can accumulate delay through sensing, communication, processing, and publication, so a recent request timestamp does not necessarily mean that the underlying vehicle observation is equally recent.
Sensing and privacy
Minimisation des données
Data minimization is the practice of limiting collected and retained information to what is necessary for a defined purpose. Curb programs can apply it by reducing identifiers, spatial detail, collection frequency, or retention, while documenting why each remaining field is required and who is authorized to access it.
Measurement and evaluation
Qualité des données
Data quality is the fitness of data for an intended use, considering dimensions such as accuracy, completeness, timeliness, consistency, and documented meaning. In curb management, quality depends on both location and rules, so a current sensor feed cannot compensate for incorrect zone boundaries or obsolete regulatory information.
Sensing and privacy
Durée de conservation des données
Data retention period is the length of time information is kept before deletion, aggregation, or another approved disposition. For curb systems, retention should match a documented operational or legal purpose, with separate treatment of raw images, identifiers, event records, and aggregate statistics rather than one indefinite default.
Street design
Dégagement de visibilité aux intersections
Daylighting is the removal or prevention of visual obstructions near an intersection or crossing. By keeping selected curb areas clear of parked vehicles or other objects, it helps people approaching a crossing see one another sooner, with the required extent determined by street conditions.
Curbside electrification
Recharge rapide en courant continu
DC fast charging is electric-vehicle charging that supplies direct current to the vehicle using conversion equipment outside the vehicle. It can support shorter energy stops than lower-power arrangements under suitable conditions, while actual charging performance depends on vehicle limits, battery state, temperature, equipment capability, and available electrical supply.
Urban logistics
Densité des livraisons
Delivery density is the concentration of delivery activity within a defined area or route, expressed using an explicitly stated unit. It may describe stops, parcels, or recipients per distance or area, so comparisons require consistent geography, time periods, and definitions rather than an unqualified density value.
Urban logistics
Optimisation des tournées de livraison
Delivery route optimization is the planning of stop sequences and routes to meet defined logistics objectives under operational constraints. Curb legality, loading access, time windows, vehicle restrictions, and service duration can all affect feasibility, so the shortest road distance is not necessarily the most workable or responsible delivery route.
Loading and passenger access
Créneau de livraison
Delivery time window is a defined period during which a delivery may occur under a regulation, contract, or appointment. Windows coordinate access to streets or premises, but their practical effect depends on travel reliability, recipient availability, unloading duration, and whether several destinations impose overlapping arrival requirements.
Logistics
Delivery Window
Créneau de Livraison
A specified time period during which deliveries are permitted or scheduled, often used to manage curb congestion and reduce conflicts.
Parking and pricing
Tarification du stationnement selon la demande
Demand-responsive parking pricing is the adjustment of parking prices using observed demand or availability under a stated policy. The aim is generally to influence use and maintain access, while effective operation requires transparent adjustment intervals, meaningful observation periods, and attention to neighboring areas and users with limited alternatives.
Policy
Demand-Responsive Pricing
Tarification Responsive à la Demande
A pricing approach that automatically adjusts rates based on real-time demand data to maintain optimal occupancy levels.
Accessibility
Surface d’éveil de vigilance
Detectable warning surface is a surface treatment designed to provide a tactile warning of a boundary or hazard to pedestrians, particularly people with vision impairments. Its required location, pattern, and contrast depend on applicable accessibility standards and should be coordinated with the surrounding curb and crossing design.
Curb management
Curb numérique
Digital curb is a machine-readable representation of curb locations, rules, and sometimes observed activity. It enables maps and information systems to describe street-edge access consistently, but its usefulness depends on accurate geometry, current regulations, clear ownership, and documented limits on what the data can establish.
Curb
Digital Curb Permit
Permis de Voirie Numérique
Electronic authorization system allowing vehicles to access specific curb zones for loading, delivery, or passenger services.
Data and standards
Arrêté de circulation numérique
Digital traffic regulation order is a machine-readable representation of a traffic regulation order, commonly called D-TRO in the United Kingdom. It makes structured restrictions available to information systems, while legal status, publication duties, data fields, and coverage depend on the relevant jurisdiction and the service implementing the digital order.
Loading and passenger access
Stationnement en double file
Double parking is the occupation of roadway space beside an already parked vehicle or curbside parking lane. It can arise from unmet loading demand or other stopping behavior, obstruct traffic and cycling, and must be distinguished from legal loading arrangements rather than treated as an inevitable delivery practice.
Measurement and evaluation
Durée de présence
Dwell time is the elapsed time that a vehicle or other observed user remains within a defined location or activity state. Curb studies must state the arrival and departure events used, because a loading session, a parking visit, and time spent waiting can produce different durations.
Curb management
Gestion dynamique du curb
Dynamic curb management is the adjustment of curb rules or allocations in response to changing conditions or observed demand. Changes can follow published decision rules rather than fixed daily schedules, so operational transparency, legal authority, understandable information, and reliable updates are central to implementation.
Parking and pricing
Tarification dynamique du stationnement
Dynamic parking pricing is parking pricing that changes according to time, demand, or other defined conditions. The term covers several operating models, so a scheme should state whether prices follow a fixed schedule, periodic reviews, or more frequent updates and how drivers learn the applicable rate before committing.
Parking
Dynamic Pricing
Tarification Dynamique
A pricing strategy that adjusts parking rates based on real-time demand, time of day, or occupancy levels to optimize space utilization and reduce congestion.
