“…The data generated by simulation models cannot be assumed to adequately represent traffic behavior in the real world. 5 Moreover, considering the limitations of regression method that traffic flow should be under saturation conditions, the HR method should derive the PCE values for roads under various traffic flow status using field data. In order to overcome the disadvantage of idealized assumption due to beforehand proposition of various vehicle classes, traffic volume and proposition of various vehicle classes are introduced to improve the HR method from the aspect of reflecting the traffic flow as realistically as possible.…”

“…Yeung obtained 1 min flow rates to estimate PCE for expressway locations in Singapore. 5 Al-Kaisy et al 19 aggregated over 15 min intervals to obtain PCE for heavy vehicles on freeways located in Canada during QDF. Fan utilized traffic flow data for each 15-min interval to account for the PCE in Singapore expressways by multiple linear regression.…”

Passenger car equivalents are used to calculate capacity and evaluate service level of urban roads. This article uses the average time headway of different car following conditions to replace the total average time headway of road vehicles, and the proportion of large vehicles to improve the headway method. This article analyzes the influence of several factors such as the proportion of large vehicles, road attributes, and traffic flow on passenger car equivalents, and obtains the following conclusions: (1) the behavior of vehicles crossing the opposite lanes has an important influence on the passenger car equivalents of the road; (2) passenger car equivalents of vertical sections at the center of central isolation belt are different from those at the start of the road; (3) the road attributes affect the passenger car equivalents; and (4) the passenger car equivalents of heavy vehicles on roads that allow two-way crossover are less than the specific value, however, the passenger car equivalents of heavy vehicles in the road segment without two-way crossing-line are greater than the specific value.

“…Besarnya nilai EMP dipengaruhi oleh faktor karakteristik operasional kendaraan, jalan, lingkungan, dan kondisi pengendalian lalu lintas. (Yeung et al, 2015;Putra, 2011;Saha et al, 2009;Al-Khaisy et al, 2002). Besarnya nilai EMP untuk ruas jalan berbeda dengan nilai EMP untuk simpang dan bundaran.…”

“…Selain itu kajian EMP baik di Indonesia ataupun di luar negeri selama ini hanya mengukur efektifitas penyediaan infrastruktur jalan terhadap moda transportasi (Yeung et al, 2015;Putra, 2011;Saha et al, 2009;Al-Khaisy et al, 2002).…”

“…Dari hasil analisis lapangan bila dibandingkan dengan nilai EMP pada MKJI 1997 seperti terlihat pada Tabel 1 dan Tabel 2.Hal ini sejalan dengan Yeung et al (2015) dan Saha et al (2009) bahwa aturan EMP harus menyesuaikan karakteristik dari pengguna jalan dan bisa berbeda antara daerah satu dengan daerah lain. Dalam Tabel 1 dan Tabel 2 terlihat bahwa nilai EMP sepeda motor pada jalan perkotaan terbagi maupun tak terbagi lebih besar dibandingkan dengan MKJI 1997.…”
