It would be desirable to use the poorEnvironmentTypeEnum within a MeasuredDataPublication (specifically to distinguish between Fog/Haze/Smoke).
Currently the only way (without using model extensions) of providing this information appears to be via a SituationPublication.
To allow Alert C Location Referencing to manage encoding to several Location Table, e.g. to allow encoding to multiple contries Location Tables or several versions in the same country for different Clients using different versions of the Location Table, it should be needed to update the molteplicity of relations among
Point and AlertCPoint
Linear and AlertCLinear
from 1 to 0..1 to 1 to 0..n
subjectTypeOfWorks misses some very relevant literals for the urban domain:
sewer
traffic lights
public transport stop (or busstop, tramstop, taxistop, ...)
public transport infrastructure
public transport information system
metro
streetparking places
parking
district heating pipe
heat transport pipe
When the laneManagementType is set to narrowLanes, it would be excpected that the residual width of the lanes could be provided as well. Proposal is to extend impact with residualLaneWidth (like RoadWidth)
Currently the placesAtWhichApplicable attribute is only available in the networkmanagement class. That is inconvenient as the enumeration values are also very usefull in area based weatherrelated roadconditions (in region x slippery roads on bridges)
It is my proposal to move this attribute to the supplementaryPositionalDescription class in groupOfLocations
The reference from one situation to another is now only feasible by refering to a version of a versioned identifiable of another situation. This is not nice as it generates a lot of traffic which does add unnecesary complexity
Using this data model traffic control strategies according to a traffic management plan can be described. They include a set of routes that can be
weighted as georeferenced objects depending on the vehicle classifications. So-called input and output
triggers can be defined for Strategies on which relevant vehicles can be filtered for the strategy.
Furthermore it is possible to describe additional capacity increasing actions, such as green waves or enabeling additional lanes.
AlbrechtConsult is a consulting company specialised on planning, realisation and operation of systems related to traffic engineering. Within the last 10 years it has developed to become the leading independent IT and organisation consultant in the segment of road traffic systems, traffic management and telematics.
I have seen several times the need to say just "road blocked" or "exit slip road blocked". This is not possible today in DATEX because road blocked is underneath the Impact class, trafficConstrictionType attribute. Which means you have to have a situationRecord. Normally this would be the source but, if you don't know the source yet?
For road closed, which is similar, this is not a problem becuase there you can create a NetworkManagement class.
If it is a bug or not I am not sure.
The component LinearAlongLinearElement resp. PointAlongLinearElement can be attached at maximum once to the component Linear resp. Point.
But there is the need of using this container multiple times to describe the same location. In Germany, for example, there is an inter-urban georeferencing method, which can be best represented with this ISO 19148 container - in addition to some edge representation, for example.
Proposal: Change upper multiplicity for this aggreagtion from 1 to *, so that the usage of this container is not longer restricted (in each case Point and Linear).
The National Traffic Information Service (NTIS) is operated by NIS Ltd on behalf of Highways England and provides up to the minute traffic information for the strategic road network in England that carries a third of all traffic and two-thirds of all freight.
Highways England is responsible for the construction and maintenance of motorways and major trunk roads in England. This is the strategic network of roads used to move people and freight around the country. The National Traffic Information Service (NTIS) is provided by Highways England and provides a range of services to help you avoid delays and plan your journeys but also makes data available to subscribers for research purposes or for developers to include it in their own applications. See the subscriber pages of Traffic England at http://www.trafficengland.com/subscribers for further details of the services available and to subscribe.
