Pleidooi: Van 50 naar 30! (Maar niet overal)

Publication/article
Published: 2020 : Tacq, R.; Andriesse, R.; Walraad, A.; Schutte, M.; Dijkstra, A.; Godefrooij, H.
Tags: Infrastructure, Policy,
Voor de veiligheid en leefbaarheid in onze dorpen en steden zou de snelheid op veel wegen binnen de bebouwde kom verlaagd moeten worden naar 30 km/uur. Maar op een deel van de wegen blijft 50 km/uur... Read more

Topic analysis of Road safety inspections using latent dirichlet allocation: A case study of roadside safety in Irish main roads

Publication/article
Published: 2019 : Roque, C.; Cardoso, J.L.; Connell, T.; Schermers, G; Weber, R.
Tags: Infrastructure, Policy, International,
Under the Safe System framework, Road Authorities have a responsibility to deliver inherently safe roads and streets. Addressing this problem depends on knowledge of the road network safety...

Low curve radius

Publication/article
Published: 2017 (European Commission): Goldenbeld, Ch.; Schermers, G.; Petegem, J.W.H. van
Tags: Infrastructure, Policy, International,
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

Publication/article
Published: 2017 (European Commission): Goldenbeld, Ch.; Schermers, G.; Petegem, J.W.H. van
Tags: Infrastructure, Policy, International,
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

Publication/article
Published: 2016 (European Commission): Petegem, J.W.H. van; Schermers, G.
Tags: Infrastructure, Policy, International,
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

Publication/article
Published: 2016 (European Commission): Petegem, J.W.H. van; Schermers, G.
Tags: Infrastructure, Policy, International,
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

Publication/article
Published: 2016 (European Commission): Petegem, J.W.H. van; Schermers, G.
Tags: Infrastructure, Policy, International,
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

Publication/article
Published: 2016 (European Commission): Loenis, B.; Schermers, G.; Petegem, J.W.H. van
Tags: Infrastructure, Policy, International,
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...
