Basic information includes Beginning and End descriptions. Road names, Type of data (Volume, Class, Speed). The layer also includes AADT and truck percentage.

Couldn’t include any stations that didn’t have coordinates because the short count layer is dependent on them. Examples of such stations would be ones collected by the county/ This data will be included in the AADT layer since that is not dependent on coordinates

The location for 9000’s stations are temporary, and often taken where we don’t normally count. We process these counts on request from the contractor, MPO or anyone else that requests it. So even if they have a coordinate, they are not saved. 

Some reasons for this type of count would be because it was taken during a holiday (which is off limit for data collection) or taken during the school year. Since the data is not representative of the station we don’t want to keep that data.

In the second example, the data collected is representative of the station and so we’ve decided to keep it.

Usually we don’t accept data that wasn’t taken in the assigned station, but we do make an exception if our coordinate wasn’t in the correct station.

Some reasons for a retiring station‐ Same data as another station so it’s being combined into one station‐ Town is no longer maintaining to road

Since the date taken and the zipfile are not included in the final product, they do not need to match. They are merely there to help eliminate duplicates

The different coordinates were a bit more tricky and took some time. If the zipfile and date were different, we could simply compare it to the report to see which one to keep.

If they were the same, we had to track down the GPS log to see which is the correct coordinate. We’re not too sure how multiple GPS coordinates were entered into our database, but we only care about the that is in the GPS log. 

11

Page 12: 2019 Traf Mon 10 - Traffic Data Viewer · Microsoft PowerPoint - 2019 Traf Mon 10 - Traffic Data Viewer.pptx Author: MFAY Created Date: 4/4/2019 7:55:41 AM

Since this station was saved as NB/SB we cannot rely on the GPS log, since both these stations (26_9163 and 26_9172) are in the GPS log. Using our Count Tracking System (Access database) we searched for 26_0114. In this case we learned that this station’s data was also collected in Work Week 41 (in October). Now we knew to keep the GPS coordinates that matched this zipfile (R02V41a). 

We deleted the split stations (26_9163 and 26_9172) since we now have coordinates for the non split station 26_0114

NOTE: If the GPS coordinates still didn’t match, we would change them so that they do.

Possible reasons for multiple reports:‐ Taken by multiple crews (Ex. Contractor and County)‐ Counts taken in different months. ‐Multiple counts in same work week. 

NOTE: We currently can only include the report without the parenthesis. We hope to have this fixed for 2017 Short Count Layer

All of these fields help identify the location of the short count. This also helps us determine if any counts were taken outside to the station or whether the station limits need to be changed for clarification. This is explained later in the presentation.

Stations are only supposed to have one beg/end description, but if multiple entries are present, we used ArcMap to see where it fell within the station. Any multiples were corrected and will be updated on the next short count layer.

In this example, we can see that 04_2061 has two segments. Since this coordinate fell between Spring Street and East 8th Street this is the one we kept. The other description (Spring St to Grand St) was deleted.

This station was a bit more tricky. In the left picture you can see that station stretched over multiple roads. This is because this station follows a County Route. Stations that don’t follow a County Road tend to stay on the same road. The right picture shows the station broken up into the three descriptions. 

Even though the station followed multiple roads, our system picked the longest segment and choose that as the road name. So even if the count fell on a different road, it will still be listed as South Main St. Of course this doesn’t help us determine where the count was taken. 

17

Page 18: 2019 Traf Mon 10 - Traffic Data Viewer · Microsoft PowerPoint - 2019 Traf Mon 10 - Traffic Data Viewer.pptx Author: MFAY Created Date: 4/4/2019 7:55:41 AM

Following the same process as the first example, we changed the description to match where the count actually took place. South Main Street was changed to Park Ave. The beginning description was changed to School St and the end description changed to South Main Street. All other entries were deleted. 

NOTE: The AADT layer has to follow the station header, therefore you may find that the descriptions between this and the short count layer to be slightly different. They might even be different between different years for the same station.

We want the full municipality name, so we use their corresponding geocodes to fill in the missing pieces. 

NOTE: Since New York city is split into boroughs, we combined them all into one municipality, which is why all of them have a geocode of 2034. In the end it doesn’t matter which borough the count falls in, the municipality will always be City of New York.

Signing field represents route sign you might see while driving. Using the signing field, we combined the I (Interstate) with the route number (87) to create I87

TDV Route is the field name that is used in the shapefile. One the TDV website, the route number will be combined with the road name. Similar to what you see with the #5 signing.

Many roads have two routes on them, so the overlap rank and the signing determines which one will be listed on the TDV.  Ex. If a station has both a US and a NY route, only the US route to be shown because it has a higher hierarchy 

22

First: Route is more important in the first one. We’d rather have the route number displayed rather than the road name. Second: Since both of routes, we want the one with the smaller signing number. Smaller numbers are more important that larger ones. (US routes are more important than NY routes)Third: If the same signing, use route

Short count layer only has actual data, since all the data represents that specific location for that specific dateBoth actual and forecasted fields will appear in the shapefile, but their values will be the same. 

AADT layer can include both Actual or Forecasted data. This is because we can calculate the predicted AADT for counts that weren’t taken in 2016. 

24

We only want to display the full AADT (both directions) on the TDV. We used the directional codes to isolate those values. Reports will show both directions. 

25

We only ran the calculations for 2016 data, so any count that was taken in a previous year will have the field but will not have a value. It will also only be for a class count, since we wouldn’t have truck data without it.  

NOTICE: Technically it’s listed under the % HEAVY VEHICLES but it’ll be listed as Percent Truck for shapefile and TDV

We had to create separate fields so that users will see text rather than just the hyperlink. 

27

Page 28: 2019 Traf Mon 10 - Traffic Data Viewer · Microsoft PowerPoint - 2019 Traf Mon 10 - Traffic Data Viewer.pptx Author: MFAY Created Date: 4/4/2019 7:55:41 AM

We originally created some of the number fields to be text fields instead. However these needed to be changed to numeric so that it would join with the preexisting short count layer. There are many more fields listed in the shapefile, but we only chose the most important ones to display on the TDV. 

For example, it was not necessary to include the AADT Type since all the data is Actual (For the short count layer)

28

Not entirely sure what happened to have these counts map outside of the state. It's something to be looked into for the 2017 short count layer

As mentioned earlier, the shapefile will include more information than what will be shown on the TDV. Count AADT= Current AADT (because no forecasted data)Count Type = Actual (No forecasted data)

Also note, that since the current year is 2014, the truck percentage will be 0%. NOTE: Even if this were a 2016 count, the truck percentage would still be 0% because the data type is Volume only

30

NOTE: There is forecasted data because this the AADT layer. This is includes entire AADT as well as truck data (both AADT and percentages)

31

If there class data collected from previous years, that will be used as the forecasted data. If not, these values were calculated using both the Region and Functional class of the station.If that data is not available either, then the Statewide Functional Class was used instead.

SU_AADT contains the AADT for Single Unit Trucks. These don’t have trailers (hence single unit). These

include delivery and dump trucks.

CU_AADT contains AADT for Combined Unit Trucks. These do have trailers (combined units). These

include Single Trailers (F8-F10) and Multi-Trailers (F11-F13)

The final product is still in production, so the end result might be slightly different

Page 35: 2019 Traf Mon 10 - Traffic Data Viewer · Microsoft PowerPoint - 2019 Traf Mon 10 - Traffic Data Viewer.pptx Author: MFAY Created Date: 4/4/2019 7:55:41 AM

Current is on left, proposed new one is on right.

The new one has been reordered to make it easier to read. It also includes the GIS ID, Functional class in

addition to the truck data. The current one is missing the roadway name. This will be corrected in the

final product.

Also notice, that the report links have been moved to the bottom. A side panel will open to show reports

for multiple years (if available). This still has the problem of only showing one report per year. This issue

is being worked on and will hopefully be included in the 2017 TDV layers.

This is an example of the data that will be included in the AADT side panel. These reports will only be

listed if we have previous data for the station.
