The goal of this project is to create a mobile radar surveillance solution that can be placed temporarily at problem intersections throughout the state and is provided as a service with no need for agencies to purchase the equipment. From the proposed project, the information needs will be determined along with the optimal equipment including CCTV and ultimately creating an “Intersection Conflict Warning Service” where alerts, alarms and information is configured into a modular solution that is close to “plug and play” making it a very cost effective service. Another goal is to have multiple applications included in a single system to understand if there is a problem, perform studies, alert state patrol, perform crash re-creation, and provide real-time alerts and incident detection.
12 month study at several intersections or roadway locations to measure driver behavior and as necessary, develop plans for the deployment of countermeasures to address any operational challenges. This project will perform data collection activities using the Navtech Radar system and will provide a detailed summary of driver behavior at the sites and on all approaches based on day of week, time of day, weather conditions, etc. Any crashes would also be captured as well as near miss events. Possible applications and information to be collected, determined or assessed include:
1. Speed of vehicles going through intersection.
2. Speed change measurements when there is a vehicle waiting at intersection.
3. Driving behavior and stop signs by time of day:
a. Number of vehicles stopping completely (this information could help with targeted police enforcement).
b. Rolling stop speeds.
c. Blowing through stop sign. (Potential countermeasure could be the installation of an LED sign downstream that lights up with a message “Don’t Do That!!!!!”)
4. General driver behavior:
a. Does it change when someone is waiting to go through the intersection?
b. For drivers who decelerate 2 to 3 mph coming to an intersection when someone is waiting, do they exhibit more cautious behavior?
5. What is normal behavior and what is an expected baseline for typical intersections? (For example, look at % of vehicles that may “blow thru” a typical intersection but is still considered safe)
6. Mix and volume of vehicles (time stamped).
7. Turning movement counts by lane and time of day – (This could be automated by the system and would not require someone to sit at an intersection and count vehicles turning left/right or into appropriate lanes).
8. Warrants for a stop sign or traffic signal – hourly volume, turning etc. helps make a decision whether to install a stop sign, stop light or leave as is. The data collected will help to make decisions on traffic control to be deployed.
