In urban water provisioning, prices can improve efficiency, contributing to the achievement of the environmental objective. However, household responses to price changes differ widely based on the household characteristics. Analyses performed at the aggregate level ignore the implications of water demand incentives at the individual household level. A large data sample at the household level enables estimation of econometric models of water demand, capturing the heterogeneity in domestic consumption. This study estimated the domestic water demand in the city of Valencia and its elasticity, along with the demands of its different districts and neighbourhoods (intra-urban scale analysis). Water price structure in Valencia is completely different from that of other Spanish cities: it is a price structure of increasing volume (increasing rate tariffs, IRT). For this estimation, from a microdata panel at the household level, the demand function with average prices for the period 2008–2011 was estimated using panel data techniques including a fixed effect for each neighbourhood. The domestic water demand elasticity at the average price in Valencia was estimated at −0.88 (which is higher than that estimated for other Spanish cities). This value indicates an inelastic demand at the average price of the previous period, which can cause consumers to overestimate the price and react more strongly to changes.

Price and service elasticities of passenger car travel are estimated using stated preference and sample enumeration methodology. Moreover, the effects of hypothetical travel demand management policies are analyzed by changes on modal share using the elasticity estimates. The elasticity of passenger car travel with fuel price is estimated to be within the range of −0.078 to −0.171. The parameter estimate of the fare variable is estimated to be statistically insignificant in every subgroup of car users. This finding suggests that fare policies are relatively ineffective for increasing transit modal shares in Korea. Meanwhile, car users' responsiveness to changes in parking costs is estimated to be much higher than for fuel cost. This suggests that parking regulations or pricing policies may be effective in reducing travel by passenger car. The elasticity with in-vehicle time, which is a key attribute of public transport amenities, is estimated to be particularly high, implying that policy measures such as introducing express buses or express urban trains could be effective in reducing passenger car travel. The demand elasticity of service levels of mass transit represented by the degree-of-crowdedness proxy turns out to be very high. Reducing crowdedness in public transit can be very effective in attracting more passengers, or at least in retaining current patronage.

This research is about joint government founded program between Japan and India or Science and Technology Research Partnership for Sustainable development (SATREPS). The purpose of this research is to establish Low Carbon Transportation in developing countries and we choose one of major city in India, where it is Ahmedabad city of Gujarat state—west cost of India. In order to approach the target, we need to understand the current situation of traffic condition in the city. The current traffic condition in India is some chaotic because of their different driving behavior compared with the advanced countries. It is becoming the chaotic traffic condition in India by not only diving behavior during investigation of this research. The main reason of the traffic congestion comes from the unbalance between growing transportation demand and its insufficient infrastructure preparation. In this chapter, it introduces the current traffic condition based on four years monitoring of the traffic by the traffic monitoring cameras and comparison by the traffic flow theory at first. Then it introduces the new traffic analysis method especially for its traffic congestion analysis and its parameters. After the traffic congestion analysis, it summarizes conclusion and our next step from the experience.

The increase in the growth of cities and the numbers of people moving to cities in the last two decades have led to sharp increase in transportation demand and development of slums and urban sprawl. Cities like Lagos, Ibadan, Kano, Port-Harcourt and Ilorin and other areas in Nigeria are experiencing many pressure on land use such as;, free-space, transportation facilities and a host of urban related problems which urgently deserve planners’ attention. Ilorin is one of the fastest growing cities in Nigeria. The problems of transportation and land use in Ilorin can be summarized into the following: long queue of people daily at ‘bus stops’, the problem of old narrow streets in most of the unplanned areas of the city and the emerging incursion of transport infrastructural facilities into the residential areas. To address these and other urban land-use problems world-wide, various governments have put in place different urban renewal programmes, but in the case of Nigeria little impacts on the city transportation and land-use systems had taken place. This research used exploratory method to justify the essence of planning in transportation system and on land-use in order to enhance and maintain sustainable development. The paper also suggests some measures like; expansion of existing narrow roads and provision of necessary infrastructural facilities, inter modality light rail/tram, creation of modern parks at specified locations as well as enlargement of public and private partnerships-involving the Government, transport associations, financial institutions, the available universities and some other professional bodies to serve as panacea to problems highlighted.

A model of transportation demand and the interrelated supply decisions of agricultural shippers is derived over a geographic space. These shippers use prices to procure grain and to make output, mode, and market decisions. Each decision is affected by the characteristics of the region and the level of spatial competition between the shipper and its rivals. All of these factors are integrated into the model of derived demand and spatial competition. The model is applied to data that represent barge elevators on the upper Mississippi and Illinois Rivers to estimate transportation demands and gathering areas. The results provide demand elasticity estimates for annual volumes between −1.4 and −1.9, which are sizably larger than previous estimates of similar traffic. The results also indicate that inbound transportation rates to the barge shipper as well as distance to the nearest competitor have a significant influence on annual volumes. A second model, explaining the size of the market areas of elevators, is also estimated. The rates of alternative modes that compete for barge traffic as well as distance to the nearest competitor influence market areas. The results provide for a strong argument that transportation demands are elastic and that spatial market areas vary substantially with transportation rates.

The Lloyd District is a high-density commercial and residential district located a short distance from downtown Portland, Oregon. To address parking and congestion problems, the city of Portland implemented a Lloyd District Partnership Plan in September 1997. This plan consists of a number of elements aimed at curbing single-occupancy vehicle use for the commute to and from the district. This plan included parking pricing in the form of meters (whereas on-street parking had been free), discounted transit passes, and other transportation demand management strategies. The effects of these strategies on travel and parking behavior were assessed, with an emphasis on the relationship between parking pricing and mode choice. A random sample of 1,000 employees in the Lloyd District was surveyed about their travel and parking behavior before and after the installation of the new meters. Research found that, during the 1 year that had elapsed between the implementation of the Lloyd District transportation management programs and the survey information collected, the drive-alone mode for the trip to work by employees in the Lloyd District had decreased by 7 percent. For the district as a whole, the drive-alone commute share is now about 56 percent. The program strategies that have emerged as the most significant in effecting this decrease are the installation of the meters and the discounted transit pass program.

The Court of Appeals of New York held, in Council of the City of New York u. Giuliani, slip op. 02634, 1999 WL 179257 (N.Y. Mar. 30, 1999), that New York City may not privatize a public city hospital without state statutory authorization. The court found invalid a sublease of a municipal hospital operated by a public benefit corporation to a private, for-profit entity. The court reasoned that the controlling statute prescribed the operation of a municipal hospital as a government function that must be fulfilled by the public benefit corporation as long as it exists, and nothing short of legislative action could put an end to the corporation's existence.In 1969, the New York State legislature enacted the Health and Hospitals Corporation Act (HHCA), establishing the New York City Health and Hospitals Corporation (HHC) as an attempt to improve the New York City public health system. Thirty years later, on a renewed perception that the public health system was once again lacking, the city administration approved a sublease of Coney Island Hospital from HHC to PHS New York, Inc. (PHS), a private, for-profit entity.
