HERE Lanes Data Specification

Conditional Attributes

The conditional attributes in HERE Lanes can have additional characteristics beyond those of other attributes. For example, conditional attributes can be used to limit other attributes to specific days/times or a subset of vehicle types.

Date-Time Modifiers

Format Reference: Date-Time Modifiers (Condition)

A Condition can have any number of Date-Time Modifiers indicating the temporal periods at which the Condition applies. (Not all Conditions can bear Date-Time Modifiers, but most do. For example, a speed bump, coded as Traffic Calming Measures on Conditional Speed Situation, is applicable at all dates and times.)

Most typical Conditions are applied to specific days of the week (e.g., Monday through Friday), but can also be applied to other situations such as "First Monday of every month," "Every August," "First day of the month" and similar temporal ranges. There can even be an indication that the restriction is "approximately seasonal."

Date-Time modifiers can also indicate specific times of day (e.g. "5:00 A.M. to 9:00 A.M."), or approximate times of day such as "dusk to dawn" and "dawn to dusk."

Access Characteristics

Format Reference: Access Characteristics (Condition)

Any Condition can have Access Characteristics to indicate the types of traffic to which the Condition applies. This can be a subset of the Access Characteristics of the underlying Link in situations where the Condition does not apply to all traffic types. The list of traffic types is the same as with Access Characteristics attribute for Links, which are true/false values.

Values (boolean):

Autos
Buses
Carpools (High-Occupancy Vehicles)
Deliveries
Emergency Vehicles
Motorcycles
Pedestrians
Taxis
Through Traffic
Trucks
Bicycles

Lane Direction of Travel Condition

Format Reference: Lane Direction of Travel Condition

The Lane Direction of Travel Condition describes the direction of travel on a lane for specific time periods defined by Date-Time Modifiers and/or specific Access Characteristics. The Lane Direction of Travel Condition overrides the Direction of Travel attribute on the lane.

Lane Access Restriction Condition

Format Reference: Lane Access Restriction Condition

The Lane Access Restriction condition identifies situations where specified types of access characteristics are prohibited from traveling on the road at specific times. Lane Access Restriction is included only when there are Access Characteristics restrictions applicable to a subset of the lanes of a link, and date/time modifiers are present. (Full-time Lane Access Restrictions are managed by the Lane Access Characteristics attribute.)

Lane Transport Access Restriction

Topology Reference Type: Lane Parametric Range

Format Reference: Lane Transport Access Restriction Condition

The Lane Transport Access Restriction Condition is applicable to any vehicle type that is large enough to meet restrictions (trucks, non-city buses) limiting Weight, Weight per Axle(s) and Length that apply to a lane.

The following conditions are supported:

Conditional Access Restriction (Road Users, Date-Time Modifier, Dependent Access Type)
Weather Type
Physical Structure Type
Hazardous Material Type
Truck Type Restriction
Transport Restriction

Lane-Level Toll Structure

Format Reference: Lane-Level Toll Structure

Lane-Level Toll Structure identifies the presence of physical toll structures or automatic controls at entry and exit points along a toll road that require payment or ticket retrieval for passage. This Condition also identifies (per lane) the Toll Structure Type and the Method of Payment.

Specifically, the Lane-Level Toll Structure condition identifies lanes that have a different condition than the road attribute. This includes the presence of physical toll structures at any locations (except ferry terminals), and automatic controls at entry and exit points along a toll road, that require payment or ticket retrieval for passage, per lane.
