Using stop bar detector information to determine turning movement proportions in shared lanes
Turning vehicle volumes at signalized intersections are critical inputs for various transportation studies such as level of service, signal timing, and traffic safety analysis. There are various types of detectors installed ...
A signal timing assignment proposal for urban multi lane staged controlled signalised roundabouts
The relationship between the left-turning traffic volume and the storage area at signalised roundabouts is investigated, and a calculation procedure for signal timing is proposed in this paper. The parameters associated ...
Estimating intersection turning volumes from actuated traffic signal information
Actuated traffic signals usually use loop detectors. The current practice in many cities is to install four consecutive loop detectors in each lane to reduce the chance of undetected vehicles. Due to practical reasons, all ...
An offset optimization approach for coordinated signal systems with preferred measure considerations
By analyzing the limitations of existing offset optimization models about coordinated signal systems and considering the random distribution of road travel speed, we obtain an offset optimization algorithm based on the ...
Innovative detector layout for automated traffic turning volume counting
Because of many advantages, loop detectors are the most common practice for obtaining data to control intersections. However, they have some drawbacks, including the fact that multiple detectors are usually required to ...
Microsimulation Analysis of Traffic Operations at Two Diamond Interchange Types
The operational performance of standard Single Point Urban Interchange (SPUI) and Tight Diamond Interchange (TDI) has already been widely studied. In general, SPUI is more efficient than a TDI in terms of increased capacity ...
