Everyone involved in transport and spatial planning is at some stage involved with data production or analysis. Each transport survey is conducted for a set of objectives. Data obtained from these transport surveys do not follow any specific pattern, and are thus difficult to understand. At the same time, a re-search organization conducts a wide variety of surveys ranging from simple road-side interviews to the complex travel diaries, which can be either longitudinal or cross-sectional, and differences in methodology, design, and protocols will often obscure basic similarities between them. Above all, it is almost impossible to collect complete information about the existing transportation system in a single survey. Most transport surveys collect partial information and depend on other sources for more. To under-stand the interactions between the datasets obtained from different surveys, a conceptual data model as a platform to integrate transport and spatial was developed. Both the transport data and spatial data were broadly classified. Transport data was classified as travel survey data, transport data (infrastructure), and transport data (functional); Spatial data were classified into geographic data and geo-data. Individual data models were developed for each classification. These data models help in streamlining the data from longitudinal surveys and standardizing the data from cross-sectional surveys. As a final step, the independent models are integrated into a single conceptual data model that represents integrated transport and spatial data. This final model facilitates easy understanding of the relationships between various data sources and allows the users to pass the information between them Show more
