To allow meaningful interpretations of wind circulation, wind direction was converted from azimuth bearings to a set of dummy variables corresponding to the 8-point compass international convention. It also describes the data and presents the econometric strategy and effects of the PYP on CO concentrations. These types of technologies can be characterized as end-of-pipe solutions which allow firms to choose emissions independently from output to a much larger extent than the other technologies, possibly explaining why firms are more responsive to the charge.
Previous studies analyzing driving restrictions have not considered these factors. On behalf of my family, we have had a wonderful experience in Sweden. There is also evidence that PYP has increased the stock of private vehicles — an outcome that is consistent with no decrease in gasoline consumption. Haileselassie opened the doors of his country to clnpes and took us on a memorable trip.

However, such data is usually scarce. Rainfall can conpees affect CO levels via a washing effect or function as a proxy 3344 the willingness to substitute transportation mode at certain times of the day — individuals owning a car may opt to use it rather than public transport when discouraged by rain. The sources of air pollution are mainly emissions generated by the combustion of fossil fuels from industry facilities point sources and the transport sector mobile sources.
The first chapter evaluates the effectiveness of the driving restriction program Pico y Placa implemented in Bogota, Colombia to reduce congestion and air pollution. Because of the minor adjustments of PYP from tothe analysis in the next section focuses only on the initial and extended phases of se program.
The first theme is Mobile Sources. Conpez congestion charges in place incorporate price bans to mitigate congestion. In fact, there is evidence of increased CO concentrations during the implementation of drastic restrictions. Page 9 of 15 Vehicle Emissions 4. Accelerated retirement program 7. Services on Demand Article. Section 4 presents the methodology and results regarding the effects of PYP on gasoline consumption, vehicle registrations and sales, and other variables.
The implementation in phases may be in response to political resistance and public opposition, which impede the immediate introduction of drastic restrictions.
Use of subsidies 4. Indeed, the size of the short- and long-run effects may differ between phases of implementation of the program such that households with prior experience of driving restrictions might have a faster and larger adaptation response to changes in the policy than those who have not had such experience. The thesis is presented in three themes. Assessment and prediction of short term hospital admissions: One factor that complicates copnes analysis of CO concentrations is cinpes.

Section 5 brings all the previous analyses together in order to discuss the effects of switching from moderate to drastic restrictions of PYP. I would like to acknowledge the great effort that my parents have made in providing me the education which made it possible for me to reach this stage of my life. We propose that you use as a reporting year, and where asked, please specify the reporting year.
Some of us followed on the way that was built by the first ones. Using data on carbon monoxide COgasoline consumption, and vehicle sales and registration, this study shows that CO concentrations and vehicle use did not decrease in the long run, despite an initial improvement in air quality for some periods of the day in both phases of the program.
They are based on simple descriptive statistics that do not take into account the effects of factors such as meteorology, seasonality, and other unobserved time-varying components that may drive variations in traffic and pollution.

This coverage is considered satisfactory in the field of environmental science because it is 16 The equipment is in compliance with the regulations of the US-EPA referred to in the Quality Assurance Manual for measurement or monitoring systems for air pollution Secretaria de Ambiente, a. The first 15 The exception is Salaswhere precipitation is included in the model specification as a robustness check of the general estimations. To this end, the present study provides more comprehensive insights into the effectiveness of the PYP program.
It is therefore not possible to construct a continuous time series before and after the 2005 of PYP based on traffic counts.
Using a quadratic directional output distance function, we characterize changes in technical efficiency as well as patterns of substitutability in response to the policies mentioned.
The basic principles and the methodology developed in this chapter could be easily adapted to other cities using information that is available in most countries. Dee age caps 9.

Because air quality is a public good, its socially optimal level of provision cannot be ensured through markets. These lags also account for the inertia of the time series when congestion is building up to a peak or falling off from the peak, and control for any other transitory shock on CO other than PYP, for instance, transitory road construction.
