“…To reflect the different demographic factors of each destination TAZ , j , a destination choice model, as shown in Table 1, is obtained from Kalmanje and Kockelman, with home-based work (HBW) trip as the base case ( 41 ). Using this model, the utility of the trip from i to j with mode m can be estimated as Equation 5.…”

This research monetizes the access benefits of making shared autonomous vehicles (SAVs) available to residents of Texas’ Dallas-Fort Worth metroplex in the U.S. Residents’ willingness to pay for SAV access under different fares and modes was estimated and compared across the region’s 5,386 traffic zones, with emphasis on those housing the regions’ most vulnerable or access-limited travelers. Assuming a $0.50/mi SAV fare, the average per-person-trip benefit is estimated to be $0.64 per trip. With $0.50/mi SAV fare, HV mode share will be reduced from 92.4% to 40.3%, while SAV will take 55.8% of the share. However, if HVs are then disallowed (removed from everyone s mode choice set) after $0.50/mile SAVs have been added, the average net impact is estimated to be −$0.31 per trip, across the metroplex. If HVs were to be replaced by access to SAVs, the impacts are positive, with region-wide average access benefits ranging from $0.16 to $0.33 per trip, depending on the SAV fare, and urban zones have a greater access benefit than rural zones with low SAV fare. Vulnerable populations and their neighborhoods were identified based on the share of persons living below the poverty level, income per capita, share of persons aged 65 years or older, those with disabilities, those owning no vehicle, and share of persons from a racial minority group. Results suggest that the access benefits of SAVs will be higher in locations/neighborhoods housing more vulnerable populations, but some vulnerabilities (e.g., those over age 65) results in lower levels of access improvement. Across those zones with highest shares of vulnerable persons, the range of differences in welfare impacts, from adding SAVs to travelers mode choice sets, widened as fares rose. As is true with many innovations, careful attention to disadvantaged groups and thoughtful policy (via smart contracting and SAV-user subsidies by public agencies, for example) can better ensure valuable access improvements for those with limited mobility and resources.

“…Keterhubungan ini bertujuan untuk mencapai pemerataan dan pertumbuhan ekonomi yang stabil di berbagai daerah; agar dapat membawa kemajuan untuk negara Indonesia. Namun, pembangunan jalan tol juga memberikan dampak pada aspek lain, yakni lingkungan, terutama dalam hal penggunaan lahan yang ada (Kalmanje dan Kockelman, 2009). Salah satu dampak pembangunan jalan tol pada aspek lingkungan adalah perubahan lanskap pertanian menjadi jalan.…”

“…Studi ini menelusuri dan menggambarkan strategi adaptasi sosial-budaya yang dilakukan oleh petani penggarap yang terdampak pembangunan jalan tol Bocimi. Penelitian mengenai dampak pembangunan jalan tol penting dilakukan menggunakan perspektif Antropologi karena perubahan lingkungan juga berdampak pada perubahan aspek sosial dan budaya masyarakat (Kalmanje dan Kockelman, 2009).…”

The construction of Bogor-Ciawi-Sukabumi (Bocimi) toll road has indirectly affected peasants of Kampung Asri in Bogor Regency. The groundwater flow has decreased since the construction began and affected rice field irrigation. The waterways have been constructed to overcome this problem, however there were damages and water decrease continues to occur. The shortage of water led the land owners to sell their properties, which can not be cultivated for rice farming, to developers. As a consequence, peasants lost their source of income. This study describes the socio-cultural adaptive strategy of peasants at Kampung Asri who lost their source of income. This study applied a qualitative method. Data were collected through secondary data collection, observation, and in-depth interviews. The findings of this study suggest that peasants of Kampung Asri changed their farm commodity and type of income generating activities to adjust to the changing situation. This strategy depicts their adaptive strategy to save their livelihood.
