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

2013

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

“…In this respect, the estimation and modelling of CO emissions can be a useful tool for air quality managers and environmentalists to examine different transport plans (reducing personal mobility, restructuring urban area, adopting low carbon technologies) and adopt the appropriate strategies for transportation system sustainability (O'Donoghue et al 2007). Consequently, the approach developed for this case study deals with traffic related CO emissions, although it can be used for estimating other pollutants that have a major impact on the environment and human health.…”

A Methodology for Modelling Traffic Related Emissions in Suburban Areas

A methodology that integrates a computer program COPERT III for calculation of traffic emissions estimates, and a transportation modelling software CUBE VOYAGER was used to assess pollutant emissions for a suburban area, as a support for future transport planning strategies to be applied for any developing road network. COPERT III is used to obtain the carbon monoxide emission factors by accounting for the car fleet composition, characteristics and average speed. An aggregated emission parametric equation was determined and used further on for estimating network carbon monoxide emissions based upon the output of macroscopic traffic characteristics enabled by traffic simulation software, CUBE VOYAGER. The methodology and modelling results are applied here for Floreşti, a satellite town of Cluj-Napoca, Romania.

“…Consideration for emissions has been integrated into research regarding network topology and performance in the form of alternatives analyses, before and after empirical studies, and traffic signal timing considerations (see Lozano et al, 2008; O’Donoghue et al, 2007; Unal et al, 2003; Li et al, 2004; Yunpeng et al, 2008; Spall and Chin, 1997). In the specific context of network design, there have been some formulations focused on setting traffic signal timing along corridors to minimize emissions (see Medina et al, 2007; Stevanovic et al, 2009; Sharma and Mathew, 2007).…”

Traditionally, transportation road networks are designed for minimal congestion. Unfortunately, such approaches do not guarantee minimal vehicle emissions. To fill this apparent gap in network design research, an emissions network design problem and solution method is proposed in this article for the purposes of comparing to the traditional network design results. Three air pollutants are considered on two road networks. The model is formulated as a bi‐level optimization problem and a solution is approximated using a genetic algorithm. The influence of demand uncertainty is also incorporated into the model. Designing for minimal congestion tends to increase emissions of criteria air pollutants. However, not adding capacity to a road network also increases emissions of pollutants. Therefore, an optimization problem and solution method, such as the emissions network design problem and solution method presented here, is useful for identifying capacity additions that reduce vehicle emissions. It is also useful for understanding the tradeoffs between designing a network for minimal congestion versus minimal vehicle emissions.
