Modelling Transport

MODELLING TRANSPORT
 
Comprehensive Textbook Resource for Understanding Transport Modelling
 
Modelling Transport provides unrivalled depth and breadth of coverage on the topic of transport modelling. Each topic is approached as a modelling exercise with discussion of the roles of theory, data, model specification, estimation, validation, and application. The authors present the state of the art and its practical application in a pedagogic manner, easily understandable to both students and practitioners. An accompanying website hosts a solutions manual.
 
Sample topics and learning resources included in the work are as follows:
* State-of-the-art developments in the field of transport modelling, including new research and examples
* Factors to consider for better modelling and forecasting
* Information and analysis on dynamic assignment and micro-simulation and model design and specification
* Agent and Activity Based Modelling
* Modelling new modes and services
 
Graduate students in transportation engineering and planning, transport economics, urban studies, and geography programs along with researchers and practitioners in the transportation and urban planning industry can use Modelling Transport as a comprehensive reference work for a wide array of topics pertaining to this field.
