A Two-stage Equilibrium Travel Demand Model for Sketch Planning
نویسندگان
چکیده
1 This paper describes a two-stage equilibrium travel demand model. The unique feature of this model is 2 that it takes time-of-day traffic counts instead of land use and demographic data as inputs to derive spatial 3 and temporal travel demand patterns. The first stage of the model is a traffic count-based trip matrix 4 estimator; the second stage is an elastic-demand network flow estimator, which recognizes latent demand 5 shifts while performing mode split, time-of-day split, and traffic assignment in a multi-level equilibration. 6 The main purpose of this paper is to share with readers our model development, algorithm design, and 7 software implementation experiences. An example application illustrates how the model is used to 8 evaluate multi-class, multi-mode and multi-period network flow patterns for sketch planning purposes. 9

Environmentally sustainable toll design for congested road networks with uncertain demand
This paper proposes a new road toll design model for congested road networks with uncertain demand that can be used to create a sustainable urban transportation system. For policy assessment and strategic planning purposes, the proposed model extends traditional congestion pricing models to simultaneously consider congestion and environmental externalities due to vehicular use. Based on analyse...

متن کاملA Direct Demand Model of Departure Time and Mode for Intercity Passenger Trips
Travel demand is well announced as a crucial component of transportation planning. This paper aims to develop a direct demand model, denoting a more acceptable abstraction of reality, for intercity passengers in daily work and leisure trips in Tehran province. The model utilizes combined estimation across the data source, collected in 2011, of travelers originating from ...
متن کاملApplication of Discrete 3-level Nested Logit Model in Travel Demand Forecasting as an Alternative to Traditional 4-Step Model
This paper aims to introduce a new modelling approach that represents departure time, destination and travel mode choice under a unified framework. Through it, it is possible to overcome shortages of the traditional 4-step model associated with the lack of introducing actual travellers’ behaviours. This objective can be achieved through adopting discrete 3-level Nested Logit model that represen...
متن کاملLiterature Review of Traffic Assignment: Static and Dynamic
Rapid urban growth is resulting into increase in travel demand and private vehicle ownership in urban areas. In the present scenario the existing infrastructure has failed to match the demand that leads to traffic congestion, vehicular pollution and accidents. With traffic congestion augmentation on the road, delay of commuters has increased and reliability of road network has decreased. Four s...
