Current Year Estimates
Kalibrate offers a new traffic count data product, along with some background information on why they thought it was important to develop it. Kalibrate has witnessed the following facts about the sources they depend on to collect and publish traffic count data.
There is often a one-year lag time before newly collected traffic count data is published and made available to the public which includes companies like ours.
Traffic counts are not updated on a consistent, ongoing basis as the need for the information and funding for the activity drives whether the city, state, federal or other organization will collect the data or not.
In addition, their customers have expressed a need for traffic count data that reflects current market conditions. Recognizing flaws in the frequency and currency of published traffic count data and in response to the needs of their customers for more up-to-date information, Kalibrate has met these challenges using their modeling expertise.
Spatial Insights Inc, is an authorized reseller of Kalibrate® traffic counts data. TrafficMetrix® is compiled traffic information from almost 6,000 sources, including municipalities, departments of transportation and local governments. Kalibrate® then combines the data with their own field-verified traffic data gathered from on-site surveys.
Kalibrate® has just released an update to its TrafficMetrix® product, version 11.1, containing 1,277,587 traffic count locations. Note that 30,151 data points were added or updated for this release.

503,608 of the total counts in version 11.1 are dated Year 2005 or more recent. Also note that this release contains the fifteenth group of counties that we have realigned through the TIGER® Accuracy Improvement Program (a program used to improve the alignment of traffic data to the street networks). The number of realigned counties for this release is 38, bringing the total number of counties realigned thus far to 2516.
Recognizing the need of some customers for more up-to-date information than published counts, Kalibrate employed its modeling expertise to forecast current year traffic counts.
Kalibrate conducted a series of analyses before selecting a final modeling technique for its current year traffic count projections.
The Location Insite model was used to statistically analyze a number of demographic variables by correlating each to a dependent variable, which in this case was the published traffic count. This model is widely used by Kalibrate to understand key drivers and their importance in a number of diverse industries. The demographic data used in this analysis was compiled from the census block group level versus the larger county area that had been used in prior analyses. The census block group data was allocated to a variety of different trade area radii sizes surrounding each traffic point. Eight different trade area sizes, ranging from ¼ mile to 30 miles, were tested to determine the size having the best correlation to the traffic data.
The demographic data that was compiled for each trade area size surrounding each traffic point included the following:
- Base Population Data
- Income Figures
- Employee Counts (an indicator of daytime demand)
- Auto Counts per Household
All TrafficMetrix counts dated 1998 or newer were forecasted to the current year. For locations having more than 1,000 cars per day, at least one trend year of a previously published count was incorporated into the forecasting formula. The outliers were removed from the model. In this analysis, the outliers were defined as traffic counts growing or declining by more than 10% from the previous year count to the current year count.
After compiling the data, it was segregated into ten separate models representing the type of area (urban or rural) and the road classification (5 types based on size of count). In other words, Kalibrate built five urban models and five rural models, one for each road classification. The model was initially tested on a major metropolitan area with diverse communities and then expanded to different geographic regions including a small market. At the minimum, a correlation coefficient of .75 was maintained across all markets that were used to create and validate the traffic estimate models. Thus, at least 75% of the base traffic figures could be accounted for by the modeled variables.
Due to the success of the test markets, the model was then generated for the entire U.S. Counts older than 1998 were not forecasted due to their age and the unavailability of demographics for that historical time period which are required model inputs. Counts over 1,000 with no traffic trend data were excluded because this is a required input for the model. Counts over 1,000 with previous year counts that were more than 10% different were excluded due to the unreliability of the data.
