	Mode choice - Wikipedia, the free encyclopedia
		Mode choice analysis is the third step in the conventional four-step transportation planning model, following trip generation and trip distribution but before route assignment.
		Choice models have attracted a lot of attention and work; the Proceedings of the International Association for Travel Behavior Research chronicles the evolution of the models.
		With a choice model we are explaining the share of travelers using a mode (or the probability that an individual traveler uses a mode multiplied by the number of travelers).

		Mode choice models represent traveler decisions about which vehicular mode to use as a function of level-of-service (LOS) characteristics of the mode and traveler and household characteristics.
		Mode choice models require a number of inputs, many of which are produced in earlier steps in the modeling process.
		Mode shares by trip purpose should be subdivided into submode shares by purpose if, for example, the mode choice model estimates transit trips for walk access and drive access trips separately.

	2.5 Discrete Choice Models
		A discrete choice model predicts a decision made by an individual (choice of mode, choice of route, etc.) as a function of any number of variables, including factors that describe a bicycle or pedestrian facility improvement or policy change.
		For each group, a mode choice probability is estimated, multiplied by the total population of the groups, and summed across all groups.
		Discrete choice models assume that choices made by individuals can be predicted based on a limited set of quantifiable factors and that people are essentially rational decision-makers who seek to make choices that maximize their utility.

		This matrix is to be split by the mode choice model into one matrix for each mode of transport using the utility functions and logit model described earlier.
		For example in a very affluent area it is likely that the most important factor when making a mode choice decision is the length of time taken to make the journey whereas in a much poorer area, cost may be the most important factor.

	SECURITY CONSIDERATIONS IN TRANSPORTATION PLANNING: A WHITE PAPER By Steven E (Site not responding. Last check: 2007-11-03)
		Mode Choice --Mode choice changes as a result of security concerns are possible due to fears that arise from terrorist incidents or the prospects of them and as an indirect result of changes in the performance of modes due to security induced changes.
		It would appear that public modes offer the opportunity for terrorists to both remain anonymous and to impact groups of people; thus, one might expect individual vehicles are less likely to be targets of terrorism.
		Network redundancy or alternative modes can help do that but these are very high cost options that don’t reduce the prospects of an incident or minimize the probability of loss of life, only facilitate a return to normality after an incident.

	Predicting Mode Choice through Multivariate Recursive Partitioning (Site not responding. Last check: 2007-11-03)
		Understanding and predicting individual mode choice decisions can help address issues ranging from forecasting demand for new modes of transport to understanding the underlying traveler behavior and characteristics.
		Early research in mode choice modeling revolved, almost exclusively, around the family of logit models.
		The present paper extends prior research by developing a methodology for predicting individual mode choice based on a nonparametric classification methodology that imposes very few constraining assumptions in yielding mode choice predictions.

	The Effects of Free Parking on Commuter Mode Choice: Evidence from Travel Diary Data
		The mode choice model predicts that with free parking, 62 percent of commuters will drive alone, 16 percent will commute in carpools and 22 percent will ride transit; with a daily parking charge of $6, 46 percent will drive alone, 4 percent will ride in carpools and 50 percent will ride transit.
		The mode choice model predicts that a daily parking charge of $6 in the Portland CBD would result in 21 fewer cars driven for every 100 commuters.
		The policy variables that play a part in mode choice decisions for commuters are the parking cost and the travel time by transit, and the results suggest that raising the cost of parking at work sites and decreasing the transit travel time (by improving service and decreasing headways) will reduce the drive alone mode share.

	Argonne Transportation - Heavy Vehicle Trends
		Equally important, however, is the lack of consistent, time-series data on shipment characteristics, freight mode shares, and vehicle use.
		However, after controlling for differences in commodity classifications between the 1977 and 1997 surveys, mode shifts were shown to be confined largely to such manufacturing sectors as metal durables, paper, and chemicals.
		Until recently, it has been difficult to analyze how commodity, shipment, and modal attributes relate to shippers' mode-choice decisions either for single modes (e.g., rail vs. truck) or combinations of modes (e.g., solo truck vs. a combination of truck and rail) and to incorporate those relationships into newly calibrated freight demand models.

	Multinational Business Review: Transaction costs and bargaining power: Entry mode choice in foreign markets
		The best entry mode choice in foreign markets by a firm is determined by the firm's preferences in control terms in entrytime abroad.
		The options in the entry mode choice in foreign markets puts in light the different perceptions that the firm has concerning the distinctive types of desired control, and that on a few occasions they prove unattainable, given their demands for resource commitment.
		Based on control as the central factor in the entry mode choice and given its relationship with the bargaining power, it seems appropriate to unify transaction costs and bargaining power models, which coincide with a great number of explainable factors'.

		It is for this reason that this study focuses on a disaggregate behavioural approach to studying freight mode choice.
		In order to understand the freight mode choice it is necessary to determine the decision-making rule and the factors influencing the choice of mode.
		These studies of freight mode choice indicate that important transport service attributes are transport charge, delivery time, fast response to problems, avoidance of loss or damage, on-time collection and delivery, the availability of freight space, punctuality and a high frequency of service.

	Assessing the Hierarchy of Needs in Levels of Service
		In conducting transportation research, typically the transportation planning industry relies on mode choice models that in turn rely heavily on time-and-cost variations for trips, as well as standard demographic characterizations of system users.
		In fact, Kuppam, Pendyala, and Rahman (1999) declare attitudinal data so important in understanding mode choices that “their omission from mode choice models may be more serious than the omission of demographic variables.” (p.75).
		This project will attempt to provide a new model of how transportation system users approach their mode choices that is different from any known studies on mode choice.

	Multinational Business Review: Parent-Affiliate Agency Conflicts and Foreign Entry Mode Choice
		Previous studies on entry mode choice are diverse but fragmented, calling for a need to recognize the conflicts between organizations, and their effects on inter-organizational transactions.
		The choice of a foreign entry mode is an important corporate decision, and agency theories may help to predict the corporate choice.
		Such a relationship exists only for the related FDIs, and the results suggest that the foreign entry mode choice is affected by the management's incentives to invest in the assets with expertise rather than by the incentives to reduce personal risk through firm-level diversification.

	2.7 Discrete Choice Models: Transit Access (Site not responding. Last check: 2007-11-03)
		A nested logit form is used, for which the first-level choice is motorized vs. non-motorized, and the second-level choices are car vs. bus and walk vs. bike.
		The model coefficients were adjusted so that current access mode shares more closely matched access mode shares as reported from two sources: (1) the Metra mode of access survey for Metra stations; and (2) the intercept survey for CTA stations.
		The models were meant to be representative of the CTA and Metra systems as a whole; use of the model to predict mode choice impacts at specific stations is recommended only with caution, since other factors which vary from station to station may not be captured in the model.
