“…Their study assessed the effects of the proposed project on transport sustainability and, thus, also assumed a planning scenario. In the COSMA method, however, the decision problem is stated as: “ Given a set of information regarding a particular location and information regarding the various modes of transport, which mode is best suited to that location?” To evaluate the suitability of one mode over another, the SMCA is conducted using the five main road based modes (private vehicles, freight, pedestrian, public transport, and bicycle) as the alternatives (see Beukes et al, 2011a). Whereas Farkas (2009), Keshkamat et al (2009), and Sharifi et al (2006) used SMCA to identify routing alternatives for one or more modes of transport given a set of assessment criteria, in this research, as with that of López and Monzón (2010), the routes are predefined.…”

This article describes the COSMA (COntext Sensitive Multimodal Assessment) method that uses contextual information to develop road infrastructure recommendations for the purpose of improved road design. The method uses a GIS‐based Spatial Multi‐criteria Analysis (SMCA) that is combined with statistical clustering techniques to identify contextually similar areas along arterials. The context is defined in terms of a range of land use, socioeconomic, environmental, and transportation information, presented spatially, which are used as inputs to the SMCA. The results of this analysis describe the relative suitability of different modes of transport to locations along an arterial route. Clustering the output of this analysis allows for sections of the route with similar contexts to be identified. The attributes of these clusters are then used to derive descriptive statements of contextually appropriate operational conditions for each mode in a particular section of the route in terms of access, right of way, and independence of movement. These can be used by road designers to develop proposals for road infrastructure design. We demonstrate the workings of the method for an arterial road in Cape Town, South Africa. The method described is explicitly multimodal and sensitive to the variations in local context. It can be used by planners and roads authorities to provide additional perspective on road user needs and facility provision, and introduces quantification, and the concomitant benefits thereof, to the largely qualitative field of Context Sensitive Design.

“…Recent studies on use of multi-modal mobility have focused on the point of interchange [ 4 , 8 , 17 ]; road network spatial design [ 21 , 22 ]; or transport and social development [ 23 ]. Generally commuters utilize numerous modes when the main public transportation system stop or station is not available within walking distance or when NMT alone is not a viable option (such as for long trips).…”

In most developing countries, formal and informal transportation schemes coexist without effective and smart integration. In this paper, the authors show how to leverage opportunities offered by formal and informal transportation schemes to build an integrated multi-modal network. Precisely, the authors consider integration of rickshaws to a bus-train network, by taking into account accessibility and societal constraints. By modelling the respective networks with weighted graphs, a graph augmentation problem is solved with respect to a composite cost taking into account constraints on the use of rickshaws. The solution, is based on finding a minimum cost spanning tree of a merged graph. The method is applied in the South African context, in the city of Johannesburg where rickshaws are not yet a significant part of the transportation system. The implications of the study reveal that using non-motorised transportation services is a viable option of improving mobility in the city. The composite cost introduced herein could be used for new routing algorithm including societal, environmental, architectural contexts and commuter experiences through rating.

“…Hence, multi-scalar, multi-criteria spatial assessment tools such as Spatial Multi-Criteria Analysis (SMCA) which is possible only over GIS should be considered. SMCA has for example been used in past by Keshkamat et al [26] and Beukes et al [27] in selection of the most appropriate road alignment and in multi-modal road planning, respectively. It is expected that with the aid of SMCA, TOD-ness can be quantitatively measured and represented as a TOD index for various locations in an area.…”

Transit Oriented Development (TOD) has been a promising concept to establish land use and transport integration, thereby creating more sustainable communities. Literature suggests that the benefits of TOD are manifold but also different for each stakeholder. A literature survey furthermore reveals that there is no standard definition nor a generally accepted aim for TOD, which is not very surprising because of the different perspectives of stakeholders in the process of achieving TOD. In addition it has been found that different methods and various sets of indicators to evaluate and measure TOD have been proposed. Examination of a number of case studies shows that these methods have hardly been operationalised. To guide decision making for new transit oriented development(s) it is essential to have a framework and a tool to quantitatively measure current levels of TOD at a location and in an area. The tool also needs to be flexible and able to support participatory planning processes. This paper provides a literature survey on the TOD concept and its operationalisations and it presents a design framework for a tool that enables quantitative measurement of TOD.
