Origin and Destination

Traffic Data Introduction

WHAT?

What is Origin-Destination data?

Origin and destination data

represents movement through a geographic space, from an origin (starting point) to a destination

(ending point). Origin and destination data is sourced from smart phones and in-vehicle navigation systems.

TxDOT does not know exactly where a trip originates or is destined to. The data is based on zones as outlined in the map within the study area. TxDOT respects the privacy of the traveling public.

Example Origin and Destination Route

WHEN?

When was this data collected?

Data was collected over a six-month period from fall 2017 to spring 2018. The data includes weekday and

weekend data, as well as daily, mid-day, morning and evening peak periods.

WHO?

Who collected this data?

TxDOT purchased the data from a company called StreetLight that

collected and analyzed the data. An interactive dashboard was developed to visualize the data.

WHY?

Why is this information important to

the I-345 Feasibility Study?

A key to evaluating the alternatives is to understand the travel patterns of current users of I-345 within the

study area, and into and out of the study area. The information is not limited to the I-345 study limits.

Changes within the I-345 study limits could potentially impact other

freeways and arterials within the study area. It is important to

understand where people are coming from and going to as the study

progresses.

With the calibrated study area,

TxDOT can analyze, visualize and compare the travel patterns in the study area. There are many points and zones within the data that can provide valuable trip information to aid the study in understanding how the public is using I-345.

Following this introduction are

representative examples of the data that can be sourced from the

dashboard tool. TxDOT is only

presenting three selection points at this public meeting; however the

study has access to hundreds of data points.

WHERE?

Where was this data collected?

The data was collected within the study area (see the green outline in the graphic to the left). It was

collected at points throughout the area along mainlanes, ramps, and cross streets. Data was collected on major freeways and arterials within the study area, not just for the limits of the I-345 Feasibility Study.
