Field-Derived Freeway Passenger Car Equivalents for Congested Conditions
Transportation Research Record: Journal of the Transportation Research Board, 2015Heavy-vehicle (HV) impact on freeway operations in the Highway Capacity Manual 2010 is evaluated on the basis of values for passenger car equivalents (PCE) for buses–trucks and recreational vehicles. These values were calibrated for relatively uncongested freeway conditions [Levels of Service (LOS) A through C] because inadequate field data on HV ...

Passenger car equivalents for vehicles on Singapore expressways
Transportation Research Part A: General, 1990Abstract It is a common practice to use Passenger Car Equivalent (PCE) as a standard measure in highway design and analysis. PCE values recommended in the US Highway Capacity Manual and those used in Britain have been adopted by many Asian countries.

Delay-based passenger car equivalents for trucks at signalized intersections
Transportation Research Part A: Policy and Practice, 2000Abstract This paper presents a new methodology for computing passenger car equivalents at signalized intersections that is based on the delay concept. Unlike the commonly used headway-based methods that consider only the excess headway consumed by trucks, the delay-based approach fully considers the additional delay heavy vehicles cause on traffic ...

A revised method for the determination of passenger car equivalencies
Transportation Research Part A: General, 1980Abstract The operating characteristics of trucks and buses differ significantly from those of passenger cars. The former travel more slowly and occupy more space than do the latter. These are the two most prominent reasons for the need to determine the equivalencies of the large-size vehicles in terms of passenger cars, since passenger car ...

Developing Passenger Car Equivalency Factors for Heavy Vehicles during Congestion
Journal of Transportation Engineering, 2005The Highway capacity manual (HCM) utilizes passenger car equivalency (PCE) factors to estimate the effect of heavy vehicles on traffic stream behavior under free-flow conditions. However, these factors have been (mistakenly) used by professionals to conduct analyses for all traffic conditions, i.e., free-flow as well as forced-flow conditions.

Estimation of Passenger Car Equivalents Based on Capacity Variability
Transportation Research Record: Journal of the Transportation Research Board, 2009Passenger car equivalents are used in highway capacity analysis procedures to convert mixed traffic stream volumes into equivalent passenger car volumes. This paper presents a new empirical method for estimating passenger car equivalents for heavy vehicles on freeways. The proposed approach is based on the concept of stochastic capacities.

Developing Improved Truck Passenger Car Equivalent Values at Signalized Intersections
Transportation Research Record: Journal of the Transportation Research Board, 2014This paper describes the methodology and findings for developing improved passenger car equivalent (PCE) factors for trucks at signalized intersections on the basis of field data and simulation modeling. The Highway Capacity Manual 2010 (HCM 2010) assumes a single PCE value of 2.00 for trucks at traffic signals.

Study on Passenger Car Equivalents Based on the Emissions
ICLEM 2010, 2010The article proposes that traffic-induced emissions pose a serious threat to air quality in many metropolises. The paper stresses that the urban transport planning must be conducted under the constraint of environment. As the traffic flow on the urban roads usually is the mixed traffic flow, there is a need to analyze the mixed traffic volume to ...

Study of ETC Lane Traffic Capacity Based on Passenger Car Equivalent
CICTP 2012, 2012Freeway toll station plays an important role in Chinese expressway system, and the construction and application of ETC lane has become more and more widely. Since the flow of ETC lane traffic is uninterrupted, and it has little change in speed; the existing queuing theory is no longer fit the study of ETC lane traffic capacity. Meanwhile, uninterrupted

The estimation of passenger car equivalent for highway under oversaturated conditions
2015 International Conference on Transportation Information and Safety (ICTIS), 2015Depending on the characteristics of oversaturated traffic flow, the algorithm based on speed-density model is put forward to estimate the passenger car equivalent (PCE) in this paper. And the consistency of jam density is identified as the equivalent criterion. Utilize PCE to study the influences of various vehicles on oversaturated traffic flow. First
