Urban transportation systems are vulnerable to congestion, accidents, weather, special events, and other costly delays. Whereas typical policy responses prioritize reduction of delays under household conditions to help the efficiency of urban road systems, analytic uphold for investments that help resilience (defined as system recovery from additional disruptions) is quiet scarce. In this effort, they delineate paved roads as a transportation network by mapping intersections to nodes and road segments between the intersections to links. They built road networks for 40 of the urban areas defined by the U.S. Census Bureau. They developed and calibrated a model to evaluate traffic delays using link loads. The loads may subsist regarded as traffic-based centrality measures, estimating the number of individuals using corresponding road segments. Efficiency was estimated as the average annual detain per peak-period auto commuter, and modeled results were found to subsist nigh to observed data, with the notable exception of modern York City. Resilience was estimated as the change in efficiency resulting from roadway disruptions and was found to vary between cities, with increased delays due to a 5% random loss of road linkages ranging from 9.5% in Los Angeles to 56.0% in San Francisco. The results demonstrate that many urban road systems that operate inefficiently under household conditions are nevertheless resilient to disruption, whereas some more efficient cities are more fragile. The implication is that resilience, not just efficiency, should subsist considered explicitly in roadway project selection and justify investment opportunities related to cataclysm and other disruptions.
Existing roadway design standards emphasize the efficient movement of vehicles through a transportation network (1–4). Efficiency in this context may comprehend identification of the shortest or fastest route (1, 5–7), or the route that minimizes congestion (8). It is the primary criterion on which road networks are modeled and design alternatives are considered (6, 7, 9, 10). The Texas A&M Transportation Institute defines and reports traffic detain in urban areas as the annual detain per auto commuter (11). Other studies define efficiency as detain for the individual driver in terms of time spent pathetic or stopped (7), or connote travel time between All origin-destination pairs in the network (9). However, as the experience of any motorist in large American cities can attest, conditions beyond the scope of the roadway design, including congestion, accidents, deplorable weather, construction, and special events (for example, a marathon race), can occasions costly delays and frustrating inefficiencies that result in fuel waste, infrastructure deterioration, and increased pollution (12, 13). Evaluating road networks based only on efficiency under household operating conditions results in exiguous to no information about how the system performs under suboptimal or disrupted conditions.
Infrastructure systems that exhibit adaptive response to stress are typically characterized as resilient (14–21). Given the essential role of transportation in emergency response, provision of essential services, and economic well-being, the resilience of roadway networks has received increasing policy attention. Nonetheless, scholars hold yet to converge on a shared understanding of resilience suitable to lead design, operation, and reconstruction of roadway networks. Although resilience in infrastructure systems is characterized as a multidimensional concept (22, 23), in many engineering and civil infrastructure implementations, resilience is defined as the talent of a system to prepare for, absorb, recover from, and accommodate to disturbances (16). Specific to transportation, resilience has been defined as “the talent of the system to maintain its demonstrated even of service or to restore itself to that even of service in a specified timeframe” (24). Others portray transportation resilience as simply the talent of a system to minimize operational loss (25) or exhaust the term synonymously with robustness, redundancy, reliability, or vulnerability (26–28).
Current efforts in transportation resilience research hold focused on framework progress and quantification methods. These efforts comprehend the specification of resilience indicators, such as total traffic detain (24), economic loss (29), post-disaster maximum stream (30), and autonomous system components (31). Practical concerns with this ilk of resilience evaluation are that it relies on uncertain performance data and often omits indicators that are unquantifiable (19). Other resilience approaches apply traffic network modeling to identify locations for critical buildings (for example, hospitals and fire stations) (32), minimize trip distance for individual passengers (33), and minimize travel time across the system (12). One drawback of existing network resilience methods is that they are data-intensive, often requiring limited information about resources for unusual road system repair (26, 28) or network deportment following a disruptive event (34). Moreover, existing resilience quantification approaches lack calibration and testing across a scope of transportation systems. Because many disruptive events, and their associated consequences, are difficult to predict, resilient road systems must subsist characterized and evaluated by the capacity to accommodate to a variety of different stress scenarios. Partly because of these obstacles, joint consideration of efficiency and resilience has yet to subsist implemented for transportation networks.
Here, they study the interconnections between resilience and efficiency (20) among road transportation networks in 40 major U.S. cities. They develop an urban roadway efficiency model, calibrate it on the basis of the observed data (11) of annual detain per peak-period auto commuter, and apply the model to motif efficiency in 40 cities. Then, they model traffic response to random roadway disruptions and recalculate expected delays to determine the sensitivity of each city to loss of roadway linkages. The results may reveal famous considerations for assessing proposals for improvement of roadway infrastructure that maintain efficiency under stress conditions.
The Methods section appears here to abet clarify the subsequent sections. To develop the urban roadway efficiency model, they defined the urban area boundaries, constructed the road networks, and evaluated the population density within cities using the Census Bureau data sets (35, 36) and OpenStreetMap (OSM) data sets (37). They relied on these data to assess commuter patterns, which they used to measure efficiency and resilience of road networks.
Alternative approaches to transportation hold been offered and comprehend those based on percolation theory and cascading failures (38–40), human mobility pattern studies (41–43), queueing (44, 45), and the exhaust of historical data to prognosticate traffic. They review these approaches in the Supplementary Materials and note that the main benefit of their model is that it relies solely on readily available public data, rather than on particular data sets that may or may not subsist practical to obtain for any particular region. The model’s algorithmic simplicity allows us to account spatial topologies of cities in tall resolution including tens of thousands of nodes and links. They did not create a more accurate transportation model than the existing ones, but they were able to obtain measurable characteristics of transportation systems (average delays) using their model.
Geospatial boundaries and population density
To define geospatial boundaries for the transportation infrastructure networks, they used the U.S. Census Bureau geospatial data set (35) for urban areas—densely developed residential, commercial, and other nonresidential areas (46). They approximated the exact urban area polygon with a simplified manually drawn one (Fig. 1A) and included All roadways within 40 km (25 miles) of it in the network. For each of the links, they calculated its length on the basis of the polyline defining the link and assigned a number of lanes m and the FFSs (see the Supplementary Materials).
Fig. 1 Definition of urban areas and assignment of nodes’ population.
(A) Boston, MA-NH-RI urban area as defined by the U.S. Census Bureau shapefiles (gray background). To simplify the model and the algorithms calculating the distance from network nodes to the city boundary, they approximate each of the urban areas shapefiles with a coarse manually drawn polygon (pink outline). (B) Assignment of the number of people departing from each of the network nodes. Population distribution (color polygons; red corresponds to higher population density), Voronoi polygons (black outline), and network nodes (dots) in Downtown Boston.
We next estimated population in vicinity of each intersection i using the Census Tract data (36). To this end, they split the map into Voronoi cells centered at intersections and then evaluated the population of each cell Ni as
Above, Nt is the population of Census Tract t, and Pi and Pt are the polygons of the cell and the tract, respectively (Fig. 1B and table S2).
We built on the gravity model to generate commuting patterns. The gravity model (47) is a classical model for trip distribution assignment and is extensively adopted in most metropolitan planning and statewide travel claim models in the United States (48–51). Other trip distribution models include, for example, destination selection models (52, 53). However, these models are not as widely used in large scale, because the circumstantial data required by these models are frequently unavailable (48).
We assumed that (i) the stream of commuters from source region o to destination region d is proportional to the population at the destination Nd and that (ii) the stream of commuters depends on the distance xod between the source and destination and is given by a distance factor, P(xod). Using these assumptions, they assessed the fraction of individuals commuting from region o to destination region d, fod, as
Then, the commuter stream from source region o to destination region d is
Although individual driving habits may vary (54), they assumed that All drivers tended to optimize their commute paths such that their travel time was minimized. This assumption allowed us to motif commute paths for every origin-destination pair using inferred FFSs. To motif commuter flows between All pairs of intersections, they estimated distances xod as the distance of the shortest time path from o to d. Furthermore, in site of the distance factor P(xod), they used the distribution of trip lengths from the U.S. Federal Highway Administration National Household Travel Survey (55, 56), which they approximated with the exponential office (Fig. 2A and table S3).
Fig. 2 Model details.
(A) Distance factor P(xod) (Eq. 2) of trips given the distance between nodes (solid line) and the statistical data (bars). (B) Dependency of hasten on density for V = 100 km/hour.
Next, they defined the commuter load on each road segment as
(4)where θod(ij) is a binary variable equal to 0 when the link ij is not on the shortest path connecting nodes o and d, and 1 otherwise. Note that in Eq. 4, they only considered origins that were not farther than 30 km from the urban area limit polygon. The nodes farther than 30 km from the limit were only used as destinations to evaluate the fraction of commuters not going toward the urban area (Eq. 2).
Because most commuters travel during peak periods, commuter loads Lij can subsist regarded as traffic-based centrality measures estimating the number of individuals using corresponding road segments. Then, the cumulative time lost by All commuters is
(5)where Vij and vij are, respectively, the FFS and the actual traffic hasten along the ij road segment, lij is its length, l0 is the length correction due to traffic signals, and β is the proportionality coefficient identical for All urban areas. The summation in Eq. 5 includes only links, whose origins and destinations are within the limit polygon. A similar equation was obtained for the pathetic detain in the study of Jiang and Adeli (45), where the authors looked at the detain induced from road repairs.
The actual traffic hasten vij depends on many factors including the hasten limit, the number of drivers on the road, and road conditions. Although there exist a number of approaches to rate actual traffic hasten (57, 58), they chose to exhaust the Daganzo model (59) to derive the traffic speed, as shown in the Supplementary Materials
(6)where vmin is the minimum hasten in the traffic, vveh is the correction for the finite size of the car, and α is the proportionality coefficient (Fig. 2B).
Efficiency and resilience metrics
We measured efficiency as the average annual detain per peak-period auto commuter. In practice, lower detain means higher efficiency. There are multiple ways to map from delays to efficiency, such as taking the inverse values of delays, taking negative values of delays, etc. To avoid ambiguity and facilitate the interpretation of results, they used the delays themselves to quantify the transportation efficiency of urban areas.
We operationalized resilience through the change in traffic delays relative to stress, which is modeled as loss or impairment of roadway linkages. Looking at resilience from the network science perspective, they focused on topological features of cities, rather than on recovery resources available. Sterbenz et al. (60) evaluated a network’s resilience as a scope of operational conditions for which it stays in the acceptable service region and highlighted that remediation mechanisms drive the operational status toward improvement. They are studying how availability of alternate routes helps remediate the consequences of the initial disruption to the network. In the traffic context, the immediate impact of a given physical disruption (and the time for it to unfold) in terms of closing lanes or reducing hasten limits on affected roads will not vary much from network to network, although the number and ilk of these disruptions will. Likewise, the hasten of restoring replete functionality (through action in the physical domain) is not so much matter on the road network as it is on the nature of the disruption (snow versus earthquake versus flood) and the resources that the city allocates to such repair. The even of functionality that these repairs achieve ought to subsist the replete predisruption functionality, that is, eventually All roads can subsist fully cleared or restored. However, the immediate loss of office for a given traffic stream can very quickly subsist partially recovered after a disruption by action in the information domain, namely, rerouting of traffic. From the modern constant status at that even of functionality, replete functionality is gradually restored. Thus, their model proxies for resilience and is calibrated against the data that proxy for efficiency. At the identical time, they note that to fully capture resilience characteristics of a transportation system, it is required to resolve recovery resources available and the effectiveness of coordination between the apposite authorities. Lower additional detain corresponds to higher resilience, but using the identical reasoning that they had for efficiency, they quantified resilience through additional delays.
Together, their traffic model has three parameters (proportionality coefficient α, minimum hasten vmin, and finite vehicle size correction vveh) and is summarized in Eqs. 5 and 6. Given parameter values of the model, one can rate the total detain incurred by All commuters in any given suburban area or, equivalently, the average detain per commuter. They consume vveh = 9 km/hour and vmin = 5 km/hour and calibrate the model to determine the value of α to match the existent data on the annual average detain per peak-period auto commuter provided by the Urban Mobility Scorecard (11).
We divide the 40 urban areas into two equally sized groups for model calibration and validation, respectively. They hold found that for the 20 urban areas used for calibration, the R-squared coefficient took values in the scope (−0.01 to 0.83) (Fig. 3 and Supplementary Materials). This allows us to set model parameters α and β (see Methods) as follows: α = 4.30 × 104 hour−1 and β = 10.59. These values correspond to the Pearson coefficient of 0.91 (P = 2.17 × 10−8).
Fig. 3 Modeled and observed delays in 40 urban areas.
Pearson correlation coefficients and P values between observed and modeled delays are (0.91, 2.17 × 10−8) for the 20 cities used to calibrate the model and (0.63, 3.00 × 10−3) for the 20 cities used to validate the model. Observed delays were taken from the Texas A&M Transportation Institute Urban Mobility Scorecard (11).
To validate the model, they rate travel delays in 20 different urban areas. As seen from Fig. 3, the estimated travel delays are significantly correlated (R = 0.63, P = 3.00 × 10−3) with actual detain times (11), validating the transportation model. motif 4 is a Google Maps representation of existent and modeled results for Los Angeles and San Francisco. Road conditions under real, average traffic patterns at 8 a.m. provided by Google Maps are in Fig. 4 (A and D). Modeled conditions are given for comparison in Fig. 4 (B and E). Finally, Fig. 4 (C and F) shows the new, modeled traffic patterns that result from redistribution of travel in response to a disruption of 5% of the links.
Fig. 4 Traffic distributions.
Typical congestion at 8 a.m. for Los Angeles (top) and San Francisco (bottom) as given by Google Maps (A and D), modeled with no disruptions (B and E), and modeled with a 5% link disruption (C and F). Notably, in Los Angeles, the disruption results in traffic redistribution to smaller roads, whereas in San Francisco, it results in increased congestion along the major highways.
Our approach to model stress is inspired by percolation theory. For every independent simulation of stress, they select a finite fraction of affected road segments r at random, with the probability of failure proportional to segment length. They collect statistics for 20 realizations of the percolation. On failed segments, free-flow speeds (FFSs) are reduced to 1 km/hour (representing near-total loss), and loads L and traffic delays are then recalculated using the updated FFSs. Low-stress scenarios (r < 0.1) might subsist caused by accidents or construction. Larger disruptions might occur during power failures that disrupt traffic signals or ascetic flooding that makes many roadways nearly impassable. Finally, widespread stress might subsist caused by snow, ice, or dust storms that finger nearly the entire roadway system. motif 5 displays the analysis of detain times in six representative urban areas for the replete spectrum of adverse event severities, r ⋲ [0; 1]. In addition, fig. S5 shows the results for All urban areas. Some routes within a sole urban area experience longer delays than others. The inset of Fig. 5 shows the detain distribution for both Los Angeles, which is narrowly clustered, and Boston, where greater variability between roadways is evident. Traffic detain times grow rapidly as r increases and gain saturation (all routes pathetic at 1 km/hour) as r approaches 1. They determine the most resilient urban transportation network to subsist Salt Lake City, UT, whereas the least resilient among the 40 metropolitans is shown to subsist Washington, DC.
Fig. 5 Dependency of the additional detain on the severity of the links disruption for six representative urban areas.
Error bars exhibit connote values ± SD. The inset shows distribution densities for two selected urban areas for 1000 realizations of 5% disruption. Note that San Francisco’s unique topology makes it susceptible to failures of a diminutive number of discrete roadways, and this produces an anomalous impact at 5 to 15% disruption.
Figure 6 shows both the efficiency (in blue) and resilience response (additional delays due to 5% link disruption, in orange) for the 40 urban areas modeled. Some cities with tall efficiency under household operating conditions (that is, low delays) nevertheless exhibit low resilience (that is, a sharp augment in traffic delays) under stress. Virginia Beach, VA; Providence, RI; and Jacksonville, FL All descend into this category of urban areas in which traffic operates well under ordinary circumstances but rapidly become snarled under mild stress. On the other hand, Los Angeles is notorious for traffic delays under All conditions—yet minor stress levels result in exiguous degradation of efficiency. By contrast, household traffic delays in San Francisco are comparable to Los Angeles, but mild stress in San Francisco results in large increases in additional delays. These examples testify that resilience (that is, additional detain response to stress) is independent of household operating efficiency.
Fig. 6 Comparison of resilience and efficiency metrics.
Annual impact of 5% disruption (additional delay) has a low correlation with household annual detain per peak-period auto commuter (delay). Pearson R = 0.49, P = 1.18 × 10−3.
The disturbances affecting the road infrastructure are often complex, and their impact on the structure and office of roadway systems may subsist unknown (28, 31). These disturbances might subsist natural and irregular, such as distributed road closures caused by an earthquake or homogeneous vehicle slowing down because of a snowstorm. The disturbances might moreover subsist anthropogenic and intentional, such as a street objective or marathon race. Whatever the disturbance, the results of this analysis allow several meaningful inferences to subsist made that may hold famous implications for highway transportation policy. The first is that resilience and efficiency delineate different aspects related to the nature of transportation systems; they are not correlated and should subsist considered jointly as complementary characteristics of roadway networks.
Second, there are characteristic differences in the resilience of different urban areas, and these differences are persistent at mild, medium, or widespread levels of stress (Fig. 5). Except for San Francisco, CA, which is the most fragile of All cities represented in Fig. 5 at stress levels r < 20% but then surpassed by Boston, MA and Washington, DC, the rank ordering of urban area resilience is insensitive to stress levels. That is, cities that exhibit relatively low resilience under mild stress are the identical cities that exhibit low levels of resilience (relative to peers) under widespread roadway impairment. This suggests that the characteristics that impart resilience (such as availability or alternate routes through redundancy of links) are protective against both the intermittent outages caused by occasional car crashes and those caused by snow and ice storms. For cities without resilience, a widespread hazard such as snow may lead to a cascade of conditions (for example, crashes) that rapidly deteriorate into gridlock. This was exactly the case for Washington, DC 20 January 2016 under only 2.5 × 10−2 m or 2.5 cm of snow (61), and for Atlanta, GA 2 years earlier, which experienced 5.1 × 10−2 m or 5.1 cm of snow in the middle of the day that resulted in traffic jams that took days to disentangle (62). Whereas current explanations of these traffic catastrophes focus on the failure of roadway managers to prepare plows and emergency response equipment, Fig. 5 suggests that cities with similar climates (Memphis, TN and Richmond, VA) are less likely to subsist affected, regardless of the availability of plow or sand trucks.
The third inference follows from Fig. 6, which suggests that urban areas that upshot capital investments to reduce traffic delays under household operating conditions may nevertheless subsist vulnerable to traffic delays under mild stress conditions. Because these stressors are inevitable, whether from crashes, construction, special events, extreme weather, apparatus malfunctions, or even deliberate attack, investment strategies that prioritize reduction of household operating delays may hold the unintended consequence of exacerbating tail risks—that is, the risk of worse catastrophe under unlikely but workable conditions.
Finally, the exceptional position of modern York City in Fig. 3 calls attention to the fact that substitutes for roadway transportation are available in many cities and hold an famous role to play in relieving traffic congestion. According to the Texas A&M Institute (63, 64), public transit reduces delays per peak-period auto commuter in the modern York urban area by 63 hours, in Chicago by 23 hours, and by less than 20 hours in other urban areas. Because their model considers only roadway transit, and modern York City contains a myriad of nonroad-based options to avoid roadway congestion, it is unlikely that their model can provide informative results for the modern York urban area.
Although interest has increased in policies that enhance roadway resilience, few analytic tools are available to lead modern investments in achieving resilience goals. It is widely understood that roadway infrastructure is expensive, both in acquiring land for rights-of-way and in construction of improvements, and thus, decisions regarding alignment, crossing, and access made over a age of decades may hold long-lasting consequences that are observable in traffic data today. Consequently, urban areas exhibit different unintentional traffic characteristics, including delays under household and random stress conditions. Investments motivated exclusively by expected efficiencies under household operating conditions are unreliable safeguards against loss of efficiency under stress conditions. Therefore, modern analytic tools are required that allow designers to assess the adaptive capacity of roadway infrastructure and assess the potential of modern investments to provide enhanced resilience. The adaptive network-based model described herein is one such approach.
