Using this website you can download traffic pattern data of the area displayed on the map, as well as the topological data of how the links are connected to each other and their attributes (length, latitude, longitude, etc.).
Simply move the map to the desired area and push the "Request Data" button. Once the data is loaded, you can download it by pushing the "Download Map Data" and "Download Speed Data" buttons. You also need to download the "Traffic Pattern Table" data to trabslate speed pattern data into actual speed values in kph.
You can search for different locations and then drag corners of the blue rectangle on the map to download data of the selected area.
| Geographical Data Description | |
|---|---|
| Attribute | Description |
| LINK_ID | Permanent link ID. Positive 64 bit Integer that globally identifies the road, carto or building footprint link, also across map releases. Link IDs are never reused. |
| REF_NODE_ID | ID for the reference node of the link. The reference node is the node with the lower left latitude (and z level). |
| NONREF_NODE_ID | ID for the non reference node of the link. The non reference node is the node with the upper right latitude. |
| LAT | Latitude coordinates [10^-5 degree WGS84] of the reference node and the non reference node. Comma separated. Each value is relative to the previous. |
| LON | Longitude coordinates [10^-5 degree WGS84] of the reference node and the non reference node. Comma separated. Each value is relative to the previous. |
| ZLEVEL | (-4 ... 11) indicates the height of the point relative to another point on a grade separated crossing with any other line. Comma separated. If z-level is null then the value '0' is left out. |
| ENTER_ANGLE | Heading when entering the link at the reference node, degree clockwise from North.This value is not map content, but computed from the link geometry (the heading of the straight line between the node and the subsequent shape point). |
| LEAVE_ANGLE | Heading when leaving the link at the non-reference node, degree clockwise from North.This value is not map content, but computed from the link geometry (the heading of the straight line between the node and the subsequent shape point). |
| LINK_LENGTH | The link length in meter. This attribute publishes the whole link length, no matter whether the link spans across several tiles. The link length is computed by straight lines between subsequent shape points, no splines or other smoothing functions or geodesoc computations are used. |
| REF_NODE_NEIGHBOR_LINKS | Comma seperated list of LINK_IDs that are connected to this link via the reference node. If a LINK_ID is negative ('-') then this link is connected via it's non reference node. |
| NONREF_NODE_NEIGHBOR_LINKS | Comma seperated list of LINK_IDs that are connected to this link via the non reference node. If a LINK_ID is negative ('-') then this link is connected via it's non reference node. |
| Speed Data Description | |
| Attribute | Description |
| FUNCTIONAL_CLASS | Defines a hierarchical network used to determine a logical and efficient route. 1 : LEVEL 1 2 : LEVEL 2 3 : LEVEL 3 4 : LEVEL 4 5 : LEVEL 5 |
| AVG_SPEED | An static average travel speed value for the link in km/h. It is derived from the static SPEED_CATEGORY link attribute: 1->131, 2->115, 3->95, 4->80, 5->60, 6->40, 7->20, 8->8 else 0. Applications can use this attribute to relate the traffic pattern values against the default speed used by routing. AVG_SPEED attribute is deprecated please use FREE_FLOW_SPEED attribute instead. |
| LINK_ID | Permanent link ID. Positive 64 bit Integer that globally identifies the road, carto or building footprint link, also across map releases. Link IDs are never reused. |
| TRAVEL_DIRECTION | Identifies the general direction that vehicles are allowed to travel on a link or lane. B : BOTH DIRECTIONS F : FROM REFERENCE NODE T : TO REFERENCE NODE |
| F_WEEKDAY | Comma separated list of 7 pattern IDs (Sun,Mon,Tue,Wed,Thu,Fri,Sat) when driving from reference node. The static table {TRAFFIC_PATTERN} contains 4 * 24 speed values for each Pattern ID. |
| T_WEEKDAY | Comma separated list of 7 pattern IDs (Sun,Mon,Tue,Wed,Thu,Fri,Sat) when driving to reference node. The static table {TRAFFIC_PATTERN} contains 4 * 24 speed values for each Pattern ID. |
| FREE_FLOW_SPEED | A free flow speed value of the link in km/h. A NULL value in this attribute means no free flow speed information is available for that link. |
