Passing Lane Effectiveness on Two-Lane Roads

IN T R O D U C T IO N A passing lane is an added lane provided in one or both directions of travel on a conventional tw o-lane highw ay to im prove passing oppo r­ tunities. T his definition includes passing lanes in level or rolling terra in , clim bing lanes on grades, and short four-lane sections. T he length of the added lane can vary from 1,000 feet as m uch as 3 miles. Figure 1 illustrate...

Overtaking Prohibition Safety Effects on Two Lane Rural Roads

This paper presents the results of a cost-effectiveness study concerning the effects of an overtaking prohibition on two lane rural roads. Overtaking prohibitions are being implemented in the Netherlands aiming to improve safety. Overtaking frequency on road sections with and without overtaking prohibition are measured by means of camera observations Overtaking frequencies were determined by co...

Wrong Roadway Detection for Multi-lane Roads

The paper contributes to the detection of driving on the wrong side of the road by addressing in particular multi-lane road situations. We suggest a solution using video data of a single camera only for identifying the current lane of the ego-vehicle. GPS data are used for knowing defined constraints on driving directions for the current road.

Headway distribution models of two-lane roads under mixed traffic conditions: a case study from India

Introduction The time headway of vehicles is of fundamental importance in traffic engineering applications like capacity, levelof-service and safety studies. Further, the performance of traffic simulation depends on inputs into the simulation process and ‘accurate vehicle generation’ is critical in this context. Thus, it is important to define headway distribution pattern for the purpose of ana...
