Impacts of Autonomous Vehicles on Traffic Flow Characteristics under Mixed Traffic Environment: Future Perspectives

Traffic Characteristics of Mixed Traffic Flow in Urban Arterials

Motorcycles are one of the main transportation modes in some Asian countries because of their advantages, such as better mobility and lower costs, as compared to automobiles. Most of the current designs of roads, such as speed limit and lane markings, are based on automobile traffic and not entirely suitable for motorcycles. Therefore, there is a need to further investigate the traffic characte...

Impacts of Snowy Weather Conditions on Expressway Traffic Flow Characteristics

Snowy weather will significantly degrade expressway operations, reduce service levels, and increase driving difficulty. Furthermore, the impact of snow varies in different types of roads, diverse cities, and snow densities due to different driving behavior. Traffic flow parameters are essential to decide what should be appropriate for weather-related traffic management and control strategies. T...

What do autonomous vehicles mean to traffic congestion and crash? Network traffic flow modeling and simulation for autonomous vehicles

Speed Characteristics of Mixed Traffic Flow on Urban Arterials

Speed and traffic volume data are collected on different sections of four lane and six lane roads in three metropolitan cities in India. Speed data are analyzed to fit the statistical distribution to individual vehicle speed data and all vehicles speed data. It is noted that speed data of individual vehicle generally follows a normal distribution but speed data of all vehicle combined at a sect...

Analysis of traffic flow with mixed manual and semiautomated vehicles

The introduction of semiautomated vehicles designed to operate with manually driven vehicles is a realistic near-term objective. The purpose of this paper is to analyze the effects on traffic-flow characteristics and environment when semiautomated vehicles with automatic vehicle following capability (in the same lane) operate together with manually driven vehicles. We have shown that semiautoma...
