Traffic Plugin

The Traffic Plugin is an optional geo plugin that is part of the project generation task-flow for new projects situated in the Netherlands. It provides the road system with traffic intensities.

The Roads tab of advanced (geo) options show when selection an area for a new project.

This Traffic Plugin is active when one or more of these source is active as a Geo Option :

• INWEVA
• NSL
• Infomil

In general, the Road's geoplugin for generated projects situated in the Netherlands, use the BGT or Top10NL to place road geometries. The NWB source is used to add the NWB ID to these roads, such that it can be used for matching traffic intensities.

The NWB id, listed as wvk_id, of a road near the city of Utrecht .

INWEVA

The Inweva excel showing multiple NWB-ids with corresponding hourly work day traffic intensities.

The INWEVA Excel is provided by an infrastructure department of the Dutch government. It contains year average hourly traffic intensities for work and weekdays per traffic group: Cars, Vans and Trucks. In the Tygron Platform the workday traffic intensities are matched to roads. Information from the INWEVA Excel can be matched to roads using the NWB id.

NSL

The NSL shown in their viewer. It contains traffic intensity information of the most important roads per jurisdiction.

The NSL can provide year-average hourly traffic intensities for work or week days. However, it only contains information on the most prominent roads. Information from the NSL can be matched to roads from the BGT and Top10NL, using the NWB id. When a match is found, the daily traffic intensities are converted to an hourly value in the following way:

$I_{d,t}=1.22\cdot I_{h,t}$

where,

$I_{d,t}$ is the daily traffic intensity for traffic type t.

$I_{h,t}$ is the estimated average hourly traffic intensity for traffic type t.

Infomil

An Infrastruction department of the Dutch government provides an Excel file, vi_lucht_geluid_v4.xls, that contains macro's to estimate traffic intensities for the road properties provided. The following properties are requested:

• The traffic speed based on the type of road. The type of road is determined by other geo plugins, generally selecting the road type based on road names, nwb data and bgt properties of the road (closed, semi closed, gravel or open).
• Single traffic direction or both ways.
• Amount of lanes on the road.
• Adjacent parking and bicycle lanes.
• Degree of urbanization, determined based on zip code or based on CBS Neighborhoods. Only two situations are considered: 5 or < 5.

This leads to the following categorization:

Each category returns daily traffic values per traffic type. These values are converted to hourly values by multiplying them with 1/24 and then stored in the corresponding function values for the road: Cars, Vans and Trucks;
