Evaluation of Impacts of Telecommuting in Traffic Assignment

چکیده
Telecommuting means that employees work completely or sometime at home or at remote telecommuting centres instead of daily travel to work at regular offices. Impacts of telecommuting on transport are becoming significant. This paper reviews the growth of telecommuting and analyzes the necessity to evaluate the influence of telecommuting in transport planning and control. The transport network equilibrium is applied to determine the flow pattern by maximizing the consumer surplus. The objective function is established from the demand and supply functions. The demand function is formed from the relationship between demand and the status of transport network. The supply function formulates the interaction between the travel time and the flow of links. When telecommuting is introduced, travel demand can decrease by different amounts in different areas and on different paths of the transport network. This redistributes trips in the network. In addition, the reduction of work trip demand by telecommuting leads to reduction of flows and travel time on roads at peak times. The users on roads with greater travel time will consider switching routes to roads with less travel time and that pushes the network to a new equilibrium state with a new flow pattern. Here combination of the demand function and the supply function enables us to solve above interactions and to simultaneously determine demand and the redistribution of flow pattern. The proposed model is referred to as an elastic-demand network equilibrium model.

There is a growing recognition that discrete choice models are capable of providing a more realistic picture of route choice behavior. In particular, influential factors other than travel time that are found to affect the choice of route trigger the application of random utility models in the route choice literature. This paper focuses on path-based, logit-type stochastic route choice models, i...

Traffic assignment algorithms are used to determine possible use of paths between origin-destination pairs and predict traffic flow in network links. One of the main deficiencies of ordinary traffic assignment methods is that in most of them one measure (mostly travel time) is usually included in objective function and other effective performance measures in traffic assignment are not considere...

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...
