Task 3 Development of Integrated Urban Land Use and Transport Strategy

Task 3-4 Development of Urban Land Use and Transport Strategy

Each combination of transport network and urban growth scenario developed in the previous tasks should be assessed using the transport demand model. Land use patterns will be included in the modelling analyses, in terms of a specific distribution of residential population and employment. This information is required for each of the growth scenarios. Based on these results, a desirable urban development strategy will be proposed. Figure 9 illustrates the process.

A reduction in travel demand can be achieved by various land-use planning measures in relation to transport development strategies. Examples of such policies are shown below:

  • Major developments should be located in areas served by public transport, or public transport provision will be required as part of major land use development.
  • The planning agency and developers ensure adequate facilities are provided for pedestrians and NMVs. Footpaths and NMV lanes/parking/waiting areas should be provided within the planned areas, and, in particular, for schools, activity centres, commercial zones and around public transport stops/stations.

The following criteria may be used when evaluating the alternative development scenarios and for selecting a preferred scenario:

Potential for Developing Public Transport System: A preferred pattern of land use and transport system should possess a high potential for developing public transport. If the city is large enough, the potential for MRT development can be measured by the demand density along major corridors. Physical characteristics of these corridors should be suitable for MRT. In general, where the land use pattern has high density development along corridors, it is recommended to provide other forms of public transport as well. Improvement to NMT facilities will be made cost effective under such a development pattern, which leads to improved mobility for all.

Total Travel Time and Average Travel Speed: Total travel time and average travel speed are important indices for evaluating mobility. A preferred system would have a lower value for the total travel time and higher values for travel speeds on the network. The total travel time can be calculated on the basis of person trips as well as vehicle trips to better understand the mobility implications.

V/C Ratio: This index is often used for the analysis of vehicle mobility. The V/C ratio is one of the most widely used indices for measuring the degree of congestion on the network. The V/C ratios on links can be compared and analyzed. Through an analysis of V/C ratios and traffic volumes, bottleneck sections and intersections should be identified. It is often found that the road network around new development areas is very congested, with bottlenecks caused by large increases in traffic volume.

Economic Indices: An economic analysis of each development scenario may be performed to develop a preferred solution with the lowest net economic cost. If a detailed demand model is available, travel time savings, vehicle operating cost savings and required infrastructure may all be incorporated in this analysis.
