This study was designed to explore the combinational effect of roadway and traffic characteristics national rural roads on fatal serious-injury crashes in Namibia. Namibia, like many other countries Southern Africa, experiences high numbers high-severity crashes, particularly its road network. The applied Generalised Poisson regression models analyse dataset. results indicate that are almost al...

Lane detection is an essential component of Advanced Driver Assistance System. The cognition on the roads is increasing day by day due to increase in the four wheelers on the road. The cognition coupled with ignorance towards road rules is contributing to road accidents. The lane marking violence is one of the major causes for accidents on highways in India. In this work we have designed and im...

Vehicular platooning is one of the most challenging issues affecting level service (LOS) two-lane roads. This phenomenon has been involved with variables governing performance measures. Thus, to improve quality these roads and predict a comprehensive model for future plans under this phenomenon, present study aimed evaluate effect vehicular on measures then identify critical headways associated...

Abstract This paper presents an intelligent speed adaption system for vehicles on conventional roads. The fuzzy logic based expert outputs a recommended to ensure both safety and passenger comfort. includes geometrical features of the road, as well subjective perceptions drivers. It has been developed checked with real data that were measured instrumental incorporated in vehicle, several two‐la...

Long uphill stretches of single-carriageway rural roads with one lane per travel direction may reduce the Level Service (LoS), due to decreased speed heavy vehicles. In those circumstances, a slowdown traffic, resulting in formation platoons, be generated difficulty performing overtaking maneuvers safely. To solve this critical issue, an additional (climbing) for slow vehicles included road pla...

The study has four main objectives: (1) to test the correlation between different infrastructure characteristics and crash-rates, and trends; (2) to develop an Infrastructure Coefficient (IC) that represents the overall infrastructure characteristics of two-lane rural highways; (3) to develop a crash-prediction model for two-lane rural highways in which the IC developed is the independent varia...

R oad user cost is an important consideration in highway economic analyses. The two main components of this cost are (a) motorvehicle running cost and (b) travel time. Highway engineers and economists know that, for road user costs (running costs plus travel time), lower traffic volume usually provides the least unit cost; as volume increases, the cost to the user increases because of congestio...
