| This paper compares the efficiency of a single lane toll, a congestion tax applied uniformly across freeway lanes, a gasoline tax, and a transit fare subsidy at reducing traffic congestion. The model incorporates a variety of conditions required to reach an efficient outcome. These include conditions for the efficient allocation of travel among competing modes, travel at peak versus off-peak periods, and drivers with high and low time costs sorted onto faster and slower freeway lanes. Each policy violates some or all of the efficiency conditions. Under wide parameter scenarios, the single lane toll, gasoline tax, and transit subsidy forgo at least two thirds of the efficiency gains under an "ideal" congestion tax that varies across lanes. In contrast, the... |

| This paper uses analytical and numerical models to illustrate how the presence of other distortions within the transport system changes the overall welfare effect of a congestion tax. These other distortions include a transit fare subsidy, congestion on competing (unpriced) routes, accident externalities, gasoline taxes, and pollution externalities. Each of these pre-existing distortions can substantially alter the welfare effect of a congestion tax that would be predicted by a first-best analysis. If congestion taxes encourage travel on other congested routes, they can produce sizeable indirect welfare losses. In addition, induced reductions in the demand for gasoline can lead to substantial welfare losses when, as appears to be the case for European... |

| In determining the marginal cost of congestion, economists have traditionally relied upon directly measuring traffic congestion on network links, disregarding any "network effects," since the latter are difficult to estimate. While for simple networks the comparison can be done within a theoretical framework, it is important to know whether such network effects in real large-scale networks are quantitatively significant. In this paper we use a strategic transportation planning model (START) to compare marginal congestion costs computed link-by-link with measures taking into account network effects. We find that while in aggregate network effects are not significant, congestion measured on a single link is a poor predictor of total congestion costs imposed... |

| Transportation authorities have consistently failed to employ economic incentives on major roadways--i.e. time-of-day pricing or "congestion fees"--to internalize the costs of congestion. In principle at least, such tolls can easily be shown to increase social welfare by making motorists pay something closer to the full social costs of their driving decisions. In addition, recent advances in electronics make it possible to implement such fees fairly cheaply and non-intrusively. While these same authorities generally understand and acknowledge the case for using congestion fees, they also claim that their use is politically infeasible because too many motorists would suffer large increases in commuting costs. This is the puzzle: If congestion tolls truly do... |

| In this paper we report on the results of a telephone survey conducted in Southern California during August and September 1996. The purpose of the survey was to inform respondents about a set of rather complex pricing policies designed to reduce motor vehicle emissions and to estimate respondent support for those policies. After receiving extensive information about these policies, respondents were polled on whether they would support, i.e., vote for, any or all of these options. The pollution fee survey elicited support for a plan that levied a fee on vehicles in the region, depending on the vehicle's emissions per mile and on the miles driven. The sample was then split in two, with half the respondents being told that a portion of the revenues would be... |

| This paper explores the interactions between taxes on work-related traffic congestion and pre-existing distortionary taxes in the labor market. A congestion tax raises the overall costs of commuting to work and discourages labor force participation at the margin, when revenues are returned in lump-sum transfers. We find that the resulting efficiency loss in the labor market can be larger than the Pigouvian efficiency gains from internalizing the congestion externality. In contrast, if congestion tax revenues are used to reduce labor taxes the net impact on labor supply is positive, and the efficiency gain in the labor market can raise the overall welfare gains of the congestion tax by as much as 100 percent. Recycling congestion tax revenues in public... |

| In 1991, the Intermodal Surface Transportation Efficiency Act (ISTEA) changed the federal-state transportation relationship by devolving decision making to the states. In turn, states were required to work with local officials on transportation improvements. ISTEA was authorized for 1992-1997, and the Transportation Equity Act for the 21st Century continued ISTEA policies through 2003. Changes in road and bridge conditions in the rural south are examined under these new transportation policies. Federal funding trends are detailed with state funding. Overall condition of roads and bridges eligible for federal funding improved, traffic increased on all roads, but condition disparities between local roads and federally funded roads grew. |

| Economists have long advocated congestion pricing as an efficient way of allocating scarce roadway capacity. However, with a few exceptions, congestion tolls are rarely used in practice and strongly opposed by the public and elected officials. Although high implementation costs and privacy issues are alleviated as appropriate technologies are developed, the concerns that congestion pricing will adversely affect low-income travelers remain. In this paper, we use a strategic transportation planning model calibrated for the Washington, DC, metropolitan area to compare the welfare and distributional effects of three pricing schemes: value pricing (HOT lanes), limited congestion pricing, and comprehensive congestion pricing. We find that social welfare gains... |
