Transport Systems and models (Prof. Pronello) 
The framework 
Transport vs Mobility 
-
Mobility:
The whole trips of people and freight
 
-
Transport:
The system formed by the infrastructures, the vehicles, and by the 
rules of the system management.
 
Often they are used as exchangeable but actually they refer to different things, even 
in public documents there might be wrong names (mobility system, etc.). 
Sustainability is a word referred to 
transport
since it has to do with infrastructure. 
Transport economics 
Is a branch of economics that deals with the allocation of resources within the 
transport sector (highly related to civil engineering). It has differences from other 
economy branches like the spaceless, instantaneous assumption. Final good from the 
customer perspective: single trip, and it can be satisfied by different agencies and 
modes. The supply and demand theory must be complemented with the 
complications of the network infrastructure. 
-
Demand is measured in journeys made from a certain region in a given time 
-
Supply is a measure of the capacity. 
-
The price of a trip includes is the generalized cost of travel, which includes both 
money and time expenditure. 
Real GDP 
Real or by volume GDP (Gross Domestic Product) is used to measure the economical 
growth. It doesn’t take into account the variation of prices (fixed a time t_0), only 
the “volume” produced: 
GDP in value 
Gross Domestic Product in value is higher than the real one because this one 
considers the increasing of the prices due to the inflation: 
Transports and economics 
Plots for the evolution of economical growth (computed through the GDP) and 
transit and freight transportation follow the same trend, indicating a high 
correlation between the two. Transportation facilitates the decentralization, which 
will then require further transportation infrastructure in a cycle. Actor are public 
bodies, for the control and creation of regulation for the consequences of growth. 


ICT4TS – Exam summary 

Political actors: France as a study case 
-
LOTI law was written in 80’s guaranteeing the right of transport to people inside 
the country. 
-
Introduces “Loti” balances in which economical impacts of an investment in 
infrastructure has to be taken into account in the final balance. 
Issues in the increasing transportation and sustainable development 
The growth of economies and transport systems imply impacts on the environment 
that has to be taken into consideration. UN report of late 80’s: “Sustainable 
development meets needs of present without compromising future”. 
Sustainability 
Is an economic, social, and environmental concept. It is intended to allow human 
activity to develop while preserving biodiversity and natural ecosystems.
