In this work, we devise an efficient method for the land-use optimization problem based on Laguerre Voronoi diagram. Previous Voronoi diagram-based methods are more efficient and more suitable for interactive design than discrete optimization-based method, but, in many cases, their outputs do not satisfy area constraints. To cope with the problem, we propose a force-directed graph drawing algorithm, which automatically allocates generating points of Voronoi diagram to appropriate positions. Then, we construct a Laguerre Voronoi diagram based on these generating points, use linear programs to adjust each cell, and reconstruct the diagram based on the adjustment. We adopt the proposed method to the practical case study of Chiang Mai University’s allocated land for a mixed-use complex. For this case study, compared to other Voronoi diagram-based method, we decrease the land allocation error by 62.557 %. Although our computation time is larger than the previous Voronoi-diagram-based method, it is still suitable for interactive design.

The Ideal

In the past years, the concept of Transit-Oriented Development has been adopted in cities and countries including Malaysia and Singapore. The integration of land use and public transport stations through Transit Oriented Development (TOD) as part of urban and cities strategy is highly acclaimed in promoting sustainable development concept in cities development. To understand the performance of TODs implementation in Klang Valley, this study has selected eleven stations in of Mass Rapid Transit (MRT) Putrajaya Line as case studies. This paper aims to evaluate the current implementation of TODs in Malaysia, benchmarked against the TOD land use composition and percentage from Singapore’s model. The findings show that Raja Uda, Ampang Park and Persiaran KLCC stations show significant performance. However, Bandar Malaysia North station displayed poor result with the lowest percentage of residential and commercial components. All stations did not achieve the ideal TOD value for residential land use and eight out of eleven stations recorded higher than the ideal TOD value for roads. However, highest number of stations achieved the ideal TOD value for mixed-use and commercial land uses. These results would help policymakers to improve the current implementation of TODs in Malaysia.

Development Approach

Mixed-use industrial park represents a new development approach of the modern industrial parks. Complying with this tendency, the land use planning of Sino-Singapore Guangzhou Knowledge City (SSGKC) proposes land relevance, non-interference and proportion control principles; discusses various mixing-use modes of commercial service land, residential land and industrial land. The plan also put forward a new type of cluster using layout to enhance the mixed land uses and eventually shape up a new industrial park that well integrates city with Industrial Park and industry with residence.

Interdisciplinary Study

Cities struggling with congestion need options to automobile-dependent transportation and land use patterns. Multiway boulevards are one alternative. Through lanes in the middle are separated by landscaped medians from side access lanes for bicycles and slow-moving local traffic. Using a case study from Oregon's Eugene–Springfield metropolitan area, this project considers what could happen if cities built arterials as multiway boulevards. This interdisciplinary study, which included widespread stakeholder and public participation as well as detailed land use and transportation modeling, was instrumental in the Eugene Planning Commission's decision to endorse converting a portion of the arterial into a multiway boulevard. Although the case study arterial, with its existing bus rapid transit lanes, requires an unusually wide right-of-way, the results show that the arterial could better accommodate residential and mixed-use buildings at the edges if reconfigured as a multiway boulevard. Projected benefits include the possibility of supporting 8,400 dwelling units, reducing annual vehicle miles traveled by nearly 100 million miles (161 million km), and reducing annual carbon emissions by nearly 110 million lb (50 million kg). Development along the boulevard can preserve up to 1,680 acres (680 ha) of farmland and lead to an annual transportation savings per household of about $1,500. New residences could generate more than $17 million annually in property tax revenue. This study offers lessons for communities interested in promoting environmental protection, enhancing quality of life, and reducing energy consumption.
