What Happens After a Turning Movement Count Study Is Completed?
After a turning movement count study ends, the real decision-making begins. Traffic engineers and city planners review the numbers to understand actual traffic conditions at the intersection. They examine vehicle movements, delays, and conflicts during peak periods. This process helps them decide what changes are needed to improve safety and flow.
By studying the results, they can spot patterns that cause backups or crashes. The data also shows where signals, lanes, or crossings need upgrades. In simple terms, the study becomes a roadmap for smarter intersection planning. These steps help reduce congestion, shorten travel times, and make streets safer for everyone.
Understanding the Turning Count Results
After the turning movement count study, engineers convert numbers into turning movement diagrams. These diagrams show vehicle movements during morning and evening peak hours. The charts help identify long queue lengths, heavy traffic patterns, and areas with poor level of service (LOS).
This stage answers what cities do after traffic studies by translating data into clear actions. Engineers compare counts with past traffic conditions and study traffic delays. Through traffic data analysis, they create plans for intersection improvements that reduce congestion and improve intersection efficiency.
Key Data Engineers Look For After a TMC Study
Engineers focus on turning volumes, pedestrian counts, and delays. They compare turning movement diagrams with crash reports and note safety concerns during morning and evening peak hours. This helps them understand turning count results explained and prepare smarter intersection planning after TMC.
Identifying Safety Concerns
Next, engineers compare the turning movement count study results with historical crash reports. This reveals dangerous traffic patterns and risky vehicle movements. Many times, they discover conflict points where pedestrian traffic and turning vehicles meet, especially during busy peak hours.
Understanding these safety concerns shows what cities do after traffic studies to protect people. Engineers often recommend safety upgrades like protected left-turn signals or dedicated turn lanes. These changes reduce conflicts and improve intersection efficiency through better intersection planning after TMC.
Common Safety Issues Found After Traffic Studies
Typical problems include long queue lengths, rear-end crashes, and conflicts with cyclist activity. Engineers use turning count results explained and crash reports to identify these safety concerns and propose protected left-turn signal phases or a new dedicated left-turn lane.
Evaluating Level of Service
After safety checks, engineers calculate the level of service (LOS) for each approach. This rating shows how well an intersection handles traffic. Poor scores often indicate long traffic delays, low intersection efficiency, and heavy traffic conditions during peak hours.
This step plays a key role in what cities do after traffic studies. Using traffic data analysis, engineers compare LOS grades before and after proposed signal timing or dedicated turn lanes. The goal is clear: improve level of service (LOS) and support long-term congestion reduction.
LOS Grades and What They Mean
Engineers classify performance from A to F. Better grades mean smooth traffic patterns and shorter queue lengths. Poor grades show heavy traffic delays. These ratings help guide intersection planning after TMC and justify major intersection improvements.
LOS Grade Traffic Condition Typical Delay
A–B Free flow Very short delay
C–D Moderate congestion Noticeable delay
E–F Heavy congestion Long queues
Developing Improvement Options
Once engineers understand the data, they design solutions. This stage shows what cities do after traffic studies in real life. They use turning count results explained to choose options like signal timing adjustments, dedicated turn lanes, or protected left-turn signals.
Some locations need bigger infrastructure changes. Engineers may suggest roundabout conversions or road widening. These actions improve intersection efficiency, reduce traffic delays, and support safer vehicle movements and pedestrian traffic through smart intersection planning after TMC.
Typical Improvements After Turning Count Results Explained
Cities often start with signal timing changes. If problems continue, they add a dedicated left-turn lane or install protected left-turn signal phases. These steps improve traffic conditions and support long-term congestion reduction.
Improvement Type Main Benefit
Signal timing adjustments Shorter delays
Dedicated turn lanes Reduced queues
Protected signals Fewer crashes
Roundabout conversions Continuous flow
Public Review and Approval
After engineers prepare solutions, the project enters the public review process. This step shows what cities do after traffic studies before construction. City planners present intersection planning after TMC results to the community and explain the turning count results explained.
During the public review process, residents review plans, ask questions, and suggest changes. Officials consider costs, safety, and future growth. Approved projects move forward as intersection improvements or major infrastructure changes designed to improve level of service (LOS) and overall safety.
From Study Results to Construction
Once approved, engineers finalize designs and budgets. The project moves from traffic data analysis to real-world upgrades. Many projects add protected left-turn signals, improve signal timing, or build dedicated turn lanes to reduce traffic delays and boost intersection efficiency.
Conclusion
A turning movement count study is only the beginning. The real value comes from turning count results explained and careful intersection planning after TMC. This process shows what cities do after traffic studies to improve safety and efficiency.
Through traffic data analysis, better signal timing, and targeted intersection improvements, cities reduce crashes and delays. These actions lead to smoother traffic, safer crossings, and smarter streets designed for future growth.
