PIC 18F series microcontroller is used for control of signals to a specific time using port lines. In this contest we choose the Bicolor LEDs with Red and Green. The colors of the signals are illuminated by programming in the microcontroller. The aim of this paper is to generate three colors on a single traffic light instead of using three different color traffic signal lights. The purpose of t...

Delay at traffic lights is a real life problem that each of us has ever encountered. Therefore it is an ideal example for the promotion of the applicability and usefulness of mathematics. As delay is to be avoided, an optimization problem arises as a function of the time period of green lights. The function to be minimized is also another interesting discussion item. Queues at fixed-cycle traff...

In the absence of pedestrian crossing lights, finding a safe moment to cross the road is often hazardous and challenging, especially for people with visual impairments. We present a reliable low-cost solution, an Android device attached to a traffic sign or lighting pole near the crossing, indicating whether it is safe to cross the road. The indication can be by sound, display, vibration, and v...

Traffic-light labelling has been proposed as a public health intervention to improve the dietary intakes of consumers. OBJECTIVES to model the potential impact of avoiding foods with red traffic lights on the label on the energy, total fat, saturated fat, sodium, and sugars intakes of Canadian adults. METHODS Canadian adults aged 19 and older (n = 19,915) who responded to the Canadian Commu...

The problem of traffic light optimization has been studied in the past twenty years. Since too many factors in the real traffic could be involved, lots of researchers proposed different kinds of models with various assumptions. In this paper, we propose a PSO algorithm based model to investigate how to set the given traffic lights such as that the total waiting time of roads is minimized. We de...

It is becoming increasingly likely that in the future most vehicles will be semi-autonomous with communication capabilities and will possess diverse speed capabilities. The aim of this paper is to describe the creation of an integrated traffic simulation system for such settings. While behaviours such as crossing, overtaking, etc. are trivially exhibited, the implemented system includes an inte...

Populational growth increases the number of cars and makes transport infrastructure increasingly saturated. The control traffic lights by intelligent software is a promising way to solve problem caused this situation. This article addresses that occurs in urban traffic. An agent-based simulation an system proposed. solution offered as agents alleviate congestion at given location. Each agent co...

This paper presents a novel method for automatic red light runner detection on a video, which is fundamentally different from the concept of conventional red light camera systems. In principle, it extracts the state of the traffic lights and vehicle motions without any physical or electronic interconnections to the traffic light control system or the buried loop detectors. Purely from the video...

According to the forensic statistics, in Iran, 26 percent of those killed in traffic accidents are motorcyclists in recent years. Thus, it is necessary to investigate the causes of motorcycle accidents because of the high number of motorcyclist casualties. Motorcyclists' dangerous behaviors are among the causes of events that are discussed in this study. Traffic signs have the important role of...
