Proportion of journeys to work by public transport (rail, metro, bus, tram);
As much as possible use newest recourses/references. Do NOT use fake or not available sources. If they are not available you should provide me with a copy.
I need half page introduction and the reset in a table like the one provided below.
Write 2 pages about indicators/formula similar to the one on the table below but it should cover, estimate or calculate the following points:
Proportion of journeys to work by public transport (rail, metro, bus, tram);
Length of public transport network/land area;
Number of stops of public transport per km;
Cost of a monthly ticket for public transport (for 5-10 km);
Number of stops of public transport per 1000 population;
Number of stops per 1 km of public transport network;
Proportion of public transport network on fixed infrastructure/Proportion of public transport network on flexible routes;
Proportion of the area used for transport (road, rail, air, ports).
Indicators Word definition Formula Where,
annual urban spatial expansion index It is key fact in the description of the temporary change in the urban area considering the annual urban rate of growth and area.
AUSEI”t”=((U”t” -U”t-1)/” U”t” )/((N”t” –N”t-1″ “)” )×100 Ut: and Ut-1: the total urban area of study in hectares.
T is the current time.
t-1 is the former year
N is the total number of years from time t
Nt-1 is the total number of years from the former year
Annual land use change index This points out on the dynamics of the urban areas including the driving forces of the development
ALUCI_t=((LU_(a,t)-LU_(a,t-1)))/((N_t-N_(t-1)))×100
LUa,t and LUa,t-t are the total land area of land use class a in hectares.
t-1 Is current time is the former year.
N is the total number of years from time t
Nt is the total number of years from the former year
Population density index It is important in the analysis of the spatial temporal grown in the urban sector and transportation.
PDI_t=P_t/U_t
Pt is the total population.
T is the time.
Ut is the total urban land in hectares
Road density index (by area and per capita) It reflects the densification of roads and deficiencies in the infrastructure of roads within the city. They are both compared with the total urban area and population. RDI_At=(RL_t)/(UA_t )
RSI_(CAP_t )=(RL_t)/(UP_t )
RLt is the total road length in km.
UAt is the total urban area in hectares at time t.
RLt is the total road length in km.
UPt is the total urban population in the study area at time t.
Road area density index (by area, capita, and for residential land use It is developed to investigate the spatial; temporal relationship between the urban growth and transport RADI_At=(RA_t)/(UA_t )×100
RADIAt is the total density by urban area
RAt is the total road Area in hectares at time t
UAt is the total urban area in hectares at time t
UPt is the total urban population in the study area at time t
URAt is the total urban residential area in hectares at time t
Urban trip density index (per capita, for residential land use and for road area This relates to the spatial temporal urban growth and transportation designed to trace the rise in the trips in the urban growth of population and the appreciation of the residential area.
UTDI_(CAP_t )=(UT_t)/(UAR_t )
UTDI_(RES_t )=(UT_t)/(UAR_t )
UTDI_(RA_t )=((DCT_t×AVTL_t))/((RA_t))×100
UTDICAPt is the urban trip density index per capita
UTDIRESt t is the urban trip density index per residential land use area
UTDIRAt is the urban trip density index per unit of road area
UTi is the total number of urban trips all modes at time t
UARt is the total urban residential area in square metres at time t
DCTt is the daily car trips at time t
AVTLt is the average trip length at time t
RAt is the total road area at time t
Modal split change index It developed to evaluate the impact of the spatial expansion on the modal split over time.
MSCI_(a,t)=((DT_(a,t)-DT_(a,t-1)))/((DT_(a,t-1)))×100
DTa,t is the percentage of the daily trips of transport mode a at current year
DTa,t-1 is the percentage of the daily trips of transport mode a at former year.
Transportation infrastructure expansion index It is modeled to evaluate the change of the transport system in Jeddah.
TIEI_t=(TIL_(l,t)-TIL_(l,t-1))/(TIL_(l,t) )×100
TILl,t and TILl,t-1 are the total transportation infrastructure in km.
T is the current time.
t-1 is the former year
