Low curve radius

Publicatie/artikel
Gepubliceerd: 2017 (European Commission): Goldenbeld, Ch.; Schermers, G.; Petegem, J.W.H. van
Trefwoorden: Infrastructuur, Visie & beleid, Internationaal,
Average crash rates are higher on horizontal curves than on straight sections of rural two-lane highways. Radius or degree of curvature consistently tops the list of geometry variables that most...

Absence of transition curves

Publicatie/artikel
Gepubliceerd: 2017 (European Commission): Goldenbeld, Ch.; Schermers, G.; Petegem, J.W.H. van
Trefwoorden: Infrastructuur, Visie & beleid, Internationaal,
Transition curves are defined as the transition between a tangent and a circular curve. In a transition curve, the curve radius is not constant but gradually changes. These curves are often designed...

Bendiness

Publicatie/artikel
Gepubliceerd: 2016 (European Commission): Petegem, J.W.H. van; Schermers, G.
Trefwoorden: Infrastructuur, Visie & beleid, Internationaal,
Curves are considered to be a risk factor in the design of roads. Most research on the risk of curves focuses on individual curves, only a few studies focus on bendiness. Findings from those studies...

Densely spaced junctions

Publicatie/artikel
Gepubliceerd: 2016 (European Commission): Petegem, J.W.H. van; Schermers, G.
Trefwoorden: Infrastructuur, Visie & beleid, Internationaal,
Junction density has been identified as a risk factor although the results of research into the effect of junction density on crash frequency and/or crash severity (number and extent of injuries) is...

Superelevation deficiencies at curves

Publicatie/artikel
Gepubliceerd: 2016 (European Commission): Petegem, J.W.H. van; Schermers, G.
Trefwoorden: Infrastructuur, Visie & beleid, Internationaal,
The superelevation is the right-angled slope of the road surface and is part of the horizontal curve design. Driving through a curve at too high speeds can create too high centrifugal forces causing...

Larger number of lanes

Publicatie/artikel
Gepubliceerd: 2016 (European Commission): Loenis, B.; Schermers, G.; Petegem, J.W.H. van
Trefwoorden: Infrastructuur, Visie & beleid, Internationaal,
Most of the studies show that an increasing number of lanes is related to an increase in crashes. This might be partly explained by an increase in lane changing and overtaking manouevres and speed...

Narrow lanes

Publicatie/artikel
Gepubliceerd: 2016 (European Commission): Loenis, B.; Schermers, G.; Petegem, J.W.H. van
Trefwoorden: Infrastructuur, Visie & beleid, Internationaal,
Research shows that narrow lanes can have both positive and negative effects on road safety. The effect of a narrow lane on crashes often concerns only the number of crashes or total crash reduction...

Absence of paved shoulders

Publicatie/artikel
Gepubliceerd: 2017 (European Commission): Goldenbeld, Ch.; Schermers, G.; Petegem, J.W.H. van
Trefwoorden: Infrastructuur, Visie & beleid, Internationaal,
A road shoulder is the section of a roadway that lies immediately adjacent to the travel lane (or driven carriageway). The absence of a paved shoulder has been identified as a risk factor in studies...

Narrow shoulders

Publicatie/artikel
Gepubliceerd: 2016 (European Commission): Loenis, B.; Schermers, G.; Petegem, J.W.H. van
Trefwoorden: Infrastructuur, Visie & beleid, Internationaal,
A road shoulder is that section of roadway immediately adjacent to the travel lane. The shoulder can be surfaced or unsurfaced. The lack of adequate shoulder width has been identified as a risk...
