“…Ensuring that the look and feel of roads match their intended function (i.e., self-explaining road designs; Charlton et al, 2010) and matching the speed limits to the roads' visual appearance (i.e., credible speed limits; Goldenbeld & van Schagen, 2007) may represent the best option for encouraging drivers to habitually choose speeds that are safe and sustainable.…”

“…How a road looks to a driver can affect drivers' perception of their speed, and as a result influence the speed they drive, in some cases without them being aware of it (Aarts & Davidse, 2007;Charlton et al, 2010;Weller, Schlag, Friedel, & Rammin, 2008). For example, driving down a narrow road or through a tunnel is often accompanied by an exaggerated sense of speed (presumably due to an increase in the stimulation of the peripheral visual field) occasioning drivers to reduce their speeds (Recarte & Nunes, 1996;Salvatore, 1968).…”

“…Recognizable road design (e.g., lane width; roadside objects) enhances correct driver behavior and improves the interaction between vehicles, other road users and the environment [24,25]. Still, heavy freight is currently carried throughout the entire hierarchical network, regardless of the function and layout of the road.…”

A Road Network for Freight Transport in Flanders: Multi-Actor Multi-Criteria Assessment of Alternative Ring Ways

Even though road transport is an essential part of freight distribution, there is a lack of customized routing networks to convey freight over the road. The present paper addresses this deficit by proposing general principles to elaborate a regional freight route network in Flanders. However, assigning regional freight traffic to a particular road network involves complex trade-offs between multiple interests, such as corporate accessibility, communal livability, additional network links and available space. The paper recommends the multi-actor multi-criteria assessment tool (MAMCA) to incorporate stakeholder objectives in the evaluation of possible freight network scenarios. The tool is applied for the specific case of Anzegem, a road village amid regional freight attraction poles that suffers particularly from heavy freight flows. The impact of four alternative ring ways is assessed according to the interests of the involved parties and compared to the reference scenario. Results show that transport companies advocate supra-local accessibility, while governmental and citizen stakeholders value traffic safety and livability. Since the reference scenario does not comply with these critical stakeholder objectives, an alternate scenario is proposed. As such, MAMCA applications assist policy-makers in building consensus among multiple actors in the realization of transportation projects. OPEN ACCESSSustainability 2013, 5 4223

“…Charlton et al [12] describe a project undertaken to establish a self-explaining roads (SER) design programme on existing streets in an urban area. The SER design for local roads included increased landscaping and community islands to limit forward visibility, and removal of road markings to create a visually distinct road environment.…”

Purpose In many cases, it does not follow from the road design, whether the given scene is within or outside the posted built-up area. The purpose of this paper is to evaluate road scenes, how far they can be considered being of built-up and non-built-up nature, as well as to identify road scenes which are ambiguous and therefore less safe. Methods Two methods were used to assess the degree of unambiguous or ambiguous nature of road scenes. In the first approach, a survey of requested speeds at various road scenes was performed with 500 respondents. Here clearly non-builtup and built-up sites, as well as unclear sites were compared. In the second method, the recognition process of drivers was simulated by an image classification software. The classifier was trained by 100 clearly built-up and 100 non-built-up pictures. Four test runs followed, each using 200 pictures from different roads.Results From the speed choice study, results have shown that in unclear situations (e.g. transition between built-up and nonbuilt-up areas) the standard deviation of chosen speeds is higher than in unambiguous situations. In the image classification study the trained classifier worked well for road scenes which are definitely of built-up or non-built-up nature.Furthermore, as expected, for unclear situations, the classifier gave uncertain classifications. Conclusions Each of the two methods produces an output indicator, the standard deviation of speeds and the certainty score, respectively. Both indicators can serve to identify road scenes leading to uncertain and therefore risky situations.
