In this paper we present an integrated traffic management and control approach for Intelligent Vehicle Highway Systems (IVHS). These IVHS consist of interacting roadside controllers and intelligent vehicles that are organized in platoons with short intraplatoon distances, and larger distances between platoons. All vehicles are assumed to be fully automated, i.e., throttle, braking, and steering...

Traffic characteristics such as signalized intersections and high vehicle density combined with low speeds account for 12-55% increase in commute time. Increasing the number of lanes highway infrastructure can help capacity consequently reduce associated delay. However, due to human-related features driver behavior interaction well induced demand, it is recommended limit four. Recently, view ri...

This thesis is conducted to compare a crash-level severity model with an occupantlevel severity model for single-vehicle crashes on rural, two-lane roads. A multinomial logit model is used to identify and quantify the main contributing factors to the severity of rural, two-lane highway, single-vehicle crashes including human, roadway, and environmental factors. A comprehensive analysis of 5 yea...

To plan safe and comfortable trajectories for automated vehicles on highways, accurate predictions of traffic situations are needed. So far, a lot research effort has been spent detecting lane change maneuvers rather than estimating the point in time actually happens. In practice, however, this temporal information might be even more useful. This paper deals with development system that accurat...

Different studies conducted, regarding the development of statistical models used to predict crash occurrences along two-lane rural highways, around globe and particularly in Ethiopia, rely on geometric characteristics than explicitly considering measures design consistencies. Recently, issue consistency highway is emerging as an important criterion. This study therefore carried out evaluate ho...

Road lane markings play an essential role in maintaining traffic order and improving safety efficiency. Active luminous have emerged with advances technology recently. However, it is still not completely clear what impact their application will on drivers. This paper aimed to study the effectiveness of active highways at night. A driving simulation experiment was carried out based advanced simu...

This study evaluates the impact of the 65-mph speed limit on traffic safety. Using data for the years 1981 to 1995 for all 50 states, a pooled time series analysis is conducted. Separate models are estimated for state fatality rates on four categories of roads: rural interstate highways, rural noninterstate roads, all roads except for rural interstate highways, and all roads. It is reported tha...
