Process Overview
In Tennessee, many of the City of Collierville’s traffic safety projects are often the result of concerns raised by residents or other agencies, such as the local fire department. It’s up to the traffic engineering team to investigate, validate, and find affordable ways to improve safety.
The team, which supports crash analysis and response efforts, previously requested crash data from the police department through the Tennessee Integrated Traffic Analysis Network (TITAN). This allowed them to gather basic crash report information, but identifying broader trends or answering detailed questions (such as time-of-day patterns or the prevalence of specific behaviors, like distracted driving) was difficult and time-consuming.
Since adopting AASHTOWare Safety for the team’s processes, accessing and exploring crash data for the Collierville area has become much easier.
One early use case came when the fire department approached the engineering team about a particular intersection. Previously, the team had to wait for the police department to retrieve crash reports from TITAN and then piece together a pattern. Now, a quick search in Crash Query can help determine the types of crashes occurring and whether they follow a trend, all within minutes.
One of the team’s early analyses focused on an intersection just outside the city limits of Collierville. The data revealed a pattern of distracted driving and run-off-road crashes in the area. To better understand the situation, they began pulling in additional metrics to build a clearer picture of the contributing factors. Their site investigation confirmed that distracted driving was a recurring issue at the intersection.
A subsequent speed study found that drivers were also frequently speeding through this area. Based on these findings, the team implemented targeted countermeasures, including the installation of in-line rumble strips and a “Stop Sign Ahead” sign, both of which aimed to decrease run-off road crashes and increase driver awareness to reduce the risk of crashes.
The team plans to conduct a post-study analysis to determine if the countermeasures they implemented have improved distracted and speed-related crashes in the area.
Accessing crash data directly through AASHTOWare Safety and eliminating reliance on other agencies for crash data has empowered the City of Collierville’s traffic team. Now, the traffic engineers can easily access the data to conduct the analyses involved for safety projects in their community.
