The aim of this research is the evaluation and designation measurement of sustainable indicators for transportation roads
with selected case study of Palestine arterial street. Collected field data for travel speed for three links is obtained to estimate the index
for performance measures of sustainability including mobility, fuel emissions, vehicle operating cost and scio-economic impacts. The
congestion index for RSR (%) is obtained which illustrated there was a maximum reduction about 78% ,83% and 82.8% for link(1),(2)
and (3) respectively and the weighted relative speed reduction index for three links covering the whole study area is about (0.58). 85%
percentile speed about 16.82 km/hr for link(1) during the peak period. Also the 85% percentiles speed were 15.9 km/hr and 18.7 km/hr
for link(2) and (3) respectively which produced high emissions rate during the peak evening period for all links from 12:00 to 4:00 p.m.
and then reduced to rise again at the evening peak period from 5:00 to 8:00p.m. The operating cost raised during peak period due to the
reduction change in vehicle speed for all studied links in Palestine street. A 12.6 average unit cost per Km for Link(1) obtained at time
period from (12-1) p.m while for links (2) and (3) were 13 , 12.32 average unit cost per Km at (2-3) p.m. respectively. User satisfaction
also is provided through questionnaire for individual people opinion to incorporate the scio-economic impact interms of User
Satisfaction Index (USI). The overall USI user satisfaction index was 2.109 which is about 42.18 % percent which demonstrated that
the Palestine arterial street is unsustainable as far the social commuter opinion aspect is taken in consideration. The results obtained
from analysis field data provide the application of ITS improve the traffic speed operation for Link (2) and (3) significantly by about
9% and 10% respectively but show insignificant negative impact traffic speed for Link (1). Another benefit of arterial ITS is the
positive effect on environment, as depicted by the reduction in fuel consumption rate by about (8% ,9% and 6.8%) for Link (1), (2) and
(3) respectively during the peak period. Furthermore positive impact on vehicle operating cost is by reduction factor of ( 9.09%, 6.47%
and 6.06%) for Link (1), (2) and (3) respectively. The Design with sustainability requirements to reduce traffic congestion, air
pollutions, economic should be harmonically coordinated with education peoples to change their attitude behaviour aspect as a whole
community live within and understanding the transportation concept so they can provide actions to minimize recourses needs and then
reduced negative impacts.
