Travel demand management (TDM) consists of a variety of policy measures that affect the effectiveness of transportation systems by changing travel behavior. The primary objective of such TDM strategies is not to improve traffic safety, although their impact on traffic safety should not be neglected. The main purpose of this study is to simulate the traffic safety impact of conducting a teleworking scenario (i.e. 5% of the working population engages in teleworking) in the study area, Flanders, Belgium. Since TDM strategies are usually conducted at a geographically aggregated level, crash prediction models should also be developed at an aggregate level. Given that crash occurrences are often spatially heterogeneous and are affected by many spatial variables, the existence of spatial correlation in the data is also examined. The results indicate the necessity of accounting for the spatial correlation when developing crash prediction models. Therefore, zonal crash prediction models (ZCPMs) within the geographically weighted generalized linear modeling framework are developed to incorporate the spatial variations in association between the number of crashes (including fatal, severe and slight injury crashes recorded between 2004 and 2007) and other explanatory variables. Different exposure, network and socio-demographic variables of 2200 traffic analysis zones (TAZs) are considered as predictors of crashes. An activity-based transportation model framework is adopted to produce detailed exposure metrics. This enables to conduct a more detailed and reliable assessment while TDM strategies are inherently modeled in the activity-based models. In this study, several ZCPMs with different severity levels and crash types are developed to predict crash counts for both the null and the teleworking scenario. The results show a considerable traffic safety benefit of conducting the teleworking scenario due to its impact on the reduction of total vehicle kilometers traveled (VKT) by 3.15%. Implementing the teleworking scenario is predicted to reduce the annual VKT by 1.43 billion and the total number of crashes to decline by 2.6%. 相似文献

This article deals with on-street, non-free parking policy. The aim is to show how parking meter violation challenges the travel demand management policy. The literature widely admits that only the increase in the enforcement effort both deters drivers from offending and contribute to moderating car use. Nevertheless, the link between parking non-compliance, enforcement effort and travel demand has never been examined. We show that when parking meter violation behaviour, fine level choice, modal split and travel demand are connected, the fine increase paradoxically supports car use and encourages parking violation in the case of large parking congestion in particular. 相似文献

The objective of this paper is to study the effects of online user-generated “expert reviews” on travelers' behavior. After controlling for a large set of independent variables, the results show that as the number of expert reviews for a hotel increases, future traveler ratings for the hotel increase. However, the marginal effect of a greater number of expert reviews decreases. Further, as the reviewing expertise level of a traveler increases, the traveler posts more negative ratings, but the marginal effect of the level of reviewing expertise decreases. Our results also indicate that reviewing expertise can reinforce the positive effect of expert hotel reviews on travelers' rating behavior. The robustness of our results is confirmed by a Bayesian ordered logit model. Finally, the implications of the results are discussed in terms of research and practice. 相似文献

建设旅游诚信,是旅游目的地政府不可或缺的重要职责。面对当前严重的旅游诚信危机,各级政府积极投入旅游诚信建设,做了大量卓有成效的工作,但也陷入了“单边建设”、“市场进入”的误区。为此,政府必须努力走出误区,通过旅游管理职责的责任化、权限化,实现旅游诚信建设的健康、有序发展。 相似文献

Traffic exposure assessments could misclassify the extent and locations of exposure if traditional recall surveys and self-reported travel diaries do not record all participant activities. The Harbor Communities Time Location Study (HCTLS) examines the nature, extent and implications of underreported locations/trips in a case study which used portable Global Positioning Systems (GPS) devices to track the diurnal patterns and traffic exposure of 47 residents of communities near the Los Angeles–Long Beach port complex. Participants were similar to adults nationwide in time spent indoors, in-vehicle, and outdoors, but spent more time indoors at home (78% vs. 66%). Overall, participants did not report nearly half (49%) of the locations and trips identified in GPS-enhanced data on their activity diaries, resulting in about 3 h/day in unreported locations and 0.6 h/day in unreported trips. The probability of a location/trip being underreported was systematically correlated with participant and location/trip characteristics. Self-reported data missed about 50 min of heightened air pollution exposures during the 5 h/day on average participants spent in high-traffic areas and about 30 min during the 4 h/day near truck routes. GPS-enhanced methods provide opportunities to more precisely characterize exposure periods and tools to identify facility, roadway, and land use types of the greatest concern for mitigation efforts. 相似文献

Aiming at a better understanding of heterogeneous interdependencies between destination and travel party choices in tourism, this study attempts to simultaneously represent these two choices by integrating the nested logit model with the latent class modeling approach to accommodate both types of nested model structures together. Empirical analysis confirmed the effectiveness of the developed model, using a data collected from more than 2000 tourists in Japan. It was observed that on average the two types of nested model structures are almost equally shared by samples and the model structures could significantly vary with income level and gender. Influential factors related to choices of destination and travel party were also explored. Concretely speaking, travel time, attractiveness of destination and number of tourism spots were found to be important influential factors in destination choice, and gender, age, marital status have important effects on travel party choice. 相似文献
