In most of the developing countries, the metropolitan organizations do not assess the safety consequences of alternative transportation systems and one of the reasons is the lack of suitable methodology. The goal of this paper is to develop practical tools for assessing safety consequences of arterial roads in the context of long-term urban transportation plans in Dhaka city, the capital of Ban...

Nowadays, because of the growing numbers of vehicles on streets and roads, the use of intelligent controlsystems to improve driving safety and health has become a necessity. To design and implement suchcontrol systems, having information about traffic light colors is essential. There are the wide variety oftraffic lights in terms of light intensity and color. Therefore it seems that design and ...

Recently, there has been a growing demand and interest in developing methods for analyzing smartphone logs to extract traffic safety information. Because the log is high time resolution and closely related to user activities but fragmentary and myopic, it is difficult for currently available collision probability based quantitative risk assessment methods to create traffic safety maps automatic...

Traffic accidents were ranked the third among the major causes of death in Thailand. About 13,438 deaths and the death rate from traffic accident was 21.5 per 100,000 of population in 2002. The deaths and death rate varied upon the economic situation. After the economic crisis, traffic accidents were increased as well as the period of the bubble economy. In the Central region of Thailand number...

Cooperative vehicle infrastructure system (CVIS) or connected vehicles, formerly known as IntelliDrive, has emerged and is expected to provide unprecedented improvements in mobility and safety. A recent study developed a CVIS-based urban traffic control system that does not require a stop-and-go style traffic signal. A simulation-based study on the CVIS-based control found significant improveme...

There are many existing classical scheduling algorithms which can obtain better system throughput and user equality, however, they are not designed for traffic transportation environment, which cannot consider whether the transmission performance of various information flows could meet comprehensive requirements of traffic safety and delay tolerance. This paper proposes a novel downlink schedul...

background and objective : to resource allocating at national levels as results of productivity, cost calculation helps to determine the size of the problem and revealed cost benefits of injury prevention and it can also ensure the better resource using and cost benefit assessment. this study was conducted to determine the method of calculating road traffic injuries cost. materials and methods:...

This paper uses a threshold based mathematical definition to estimate capacity for future sUAS traffic in low altitude uncontrolled airspace based on safety and performance considerations. It is motivated by the need to assess the impact of large-scale close proximity unmanned aircraft operations on communities and existing manned airspace. We simulate unmanned traffic over urban areas and esti...
