Environmental monitoring networks and sharing of sensor data on the Internet contribute to the increase of public awareness and involvement in environmental sustainability. The ready-made environmental kits capture traffic-related air pollution and noise levels, and furthermore making real-time information on environmental conditions available to the public. Historical environmetal data will be collected in several hot-spots around the city of Cluj-Napoca, and further explained by traffic counts, and structural characteristics of the built environment. The aim of this project is to firstly inform the public on the levels of air and noise pollution in downtown Cluj-Napoca and other intersections with high levels of traffic, but to also develop eco-routes for non-motorized transport, in order to ensure minimum exposure to pollutants.

Air pollution monitoring requires installation of fixed and expensive monitoring stations. We are planning to deploy a network of ready-made monitoring kits out of the range of the fixed stations, in order to supplement the information of air quality and noise. Although deploying a relatively high number of static sensors throuout the city is is both cost and labor intensive, and this is the reason why we intend to install several mobile sensors on top of public transport vehicles. This will allow to further validate the measurements and calibrate the sensors.

The research topic handled the relationship between urbanization and travel demand in Romania, and entailed both macroscopic and microscopic data collection and processing, applied choice analysis and statistical modelling. The methodology and results open new directions in transportation research in Romania, and boost multidisciplinary research, due to complexity of interactions and causality between elements of the urban environment.

As few studies related to transport geography were developed for Romania, the influence of economic development on population well-being and the magnitude of urbanization in a Romanian context was analyzed. Considering the findings, another research projected the car ownership evolution at regional level.

As data scarcity allowed for limited projections, with less considerations of the human factors, an empirical analysis of mode choice behavior of the commuters in the city of Cluj-Napoca was initiated. Travel behavior survey was designed and conducted to determine the current patterns of transport mode choice for commuting, and the switching behavior towards public transport use.

A methodology that integrates a computer program COPERT III for calculation of traffic emissions estimates, and a transportation modelling software CUBE VOYAGER was used to assess pollutant emissions for the satellite town of Floresti, in Cluj-Napoca suburban area.

A traffic study was designed and conducted, and the traffic model was built, calibrated, and validated. An aggregated emission parametric equation was determined and integrated in the traffic modelling software, and further used for estimating network air pollutant emissions for two development scenarios. To best of our knowledge, the paper represented a pioneering study with the specific traffic demand management topic to be indexed in an SCI database, which relates the magnitude of urban sprawl and its effect on the mobility of individuals in Romania.
