The conflict between the mainline and incoming traffic flow in merging area of an urban expressway makes it easier to form a bottleneck than basic road section. When occurs, overall efficiency is affected. This paper establishes improved Cell Transmission Model (CTM) using Genetic Algorithms (GA) Mean Absolute Percentage Error (MAPE) for parameter calibration validation. Based on joint optimiza...

Quantum dots (QDs) have attracted tremendous interest over the last few years for a large variety of applications ranging from optoelectronic through photocatalytic to biomedical, including applications as nanophosphors in light emitting diodes LEDs [1]. QDs have been suggested as scintillators for detection of alpha particles and gamma-rays [1-4]. Quantum dots offer an improvement on scintilla...

The present article contains a microsimulation analysis of the impact number pedestrians on pedestrian crossings controlled by traffic lights. To analyze level freedom movement using HCM 2010 method based service (LOS) implemented in PTV VISSIM tool, simulation two interconnected intersections is performed. These differ inlets as well intensity vehicles at each inlets. model was real data from ...

The congestion at the PLN intersection Kaliurang street Km 8 is reason of Unofficial Officers or so-called "Pak Ogah" act as traffic regulators assist in movement driving from minor roads to major roads. Therefore, objective study was determine impact on performance intersections. survey conducted for 3 days which were volume survey, a vehicle speed, behavior, and length queue. VISSIM modeling ...

As the main road type in an urban traffic system, increasingly severe congestion of expressway restricts social and economic development. It is essential to explore evolution law dissipation ensure efficient operation expressway. In order accurately grasp flow state, this paper selects weaving section, which a frequency-changing area, study change process, law, determine state discrimination st...

In order to alleviate the influence of low-speed vehicles on tunnel safety, this paper discusses setting method variable lane boundaries in urban tunnels. VISSIM simulation software is used analyze traffic flow when changes are allowed and prohibited. The results show that average speed tunnels greatest, can be significantly alleviated dividing line. When 40 km/h set, delay time reduced by 30–5...
