Analysis of Traffic Capacity on Mountainous Two Lane Highway Adding Climbing Lane
MATEC Web of Conferences 81, 04009 (2016) DOI: 10.1051/matecconf/20168104009 ICTTE 2016 Analysis of Traffic Capacity on Mountainous Two Lane Highway Adding Climbing Lane Yunwei Meng1,2 , Hailing Li2, Hejun Chai2 and ZonglingYan 2 1The Key Laboratory of Road and Traffic Engineering, Ministry of Education, Tongji University, 201804,Shanghai, China 2China Merchants Chongqing Communications Technology Research & Design Institute Co., LTD, 400067,Chongqing, China Abstract. During the construction of mountainous double lane highway, climbing lane plays a certain role for enhancing the traffic capacity. In order to explore traffic capacity improvement effect for different conditions of climbing lane, 20 representative models are chosen, which contain various combinations of alignment and traffic parameters. The changes of traffic capacity, average speed, delays, and saturation in models are obtained before and after the use of a climbing lane by means of numerical simulation. The results show that the use of a climbing lane could improve traffic capacity, average speed, while reducing delays and saturation. The improvement effect is different according to different combinations of alignment and traffic parameters. The research could provide a reference for mountainous climbing lane construction intend. 1 Introduction found that it is possible to generate traffic bottlenecks in the lane separation and convergence position. It can Because of the limitation of geology, topography and effectively ease traffic congestion by extending the length engineering investment, two-way two lane highway is of the transition section [4]. Setting up a reasonable common form in mountainous area of China. Two lane climbing lane, it can slow down the occurrence of traffic highways in mountain area is the main artery, assuming congestion [5]. -
Spill Clean-Up Recommendations for Emergency Escape Ramps (Eers): Western Mountain Dots’ Perspectives
55th ASC Annual International Conference Proceedings Copyright 2019 by the Associated Schools of Construction Spill Clean-up Recommendations for Emergency Escape Ramps (EERs): Western Mountain DOTs’ Perspectives Deniz Besiktepe, Ph.D. Student¹, Dr. Rodolfo Valdes- Dr. Kelly Strong, Ph.D.² Vasquez, Ph.D.¹, and Dr. Scott Shuler, Ph.D.¹ ¹ Department of Construction Management, ² Department of Construction Management, Colorado State University University of Northern Iowa Fort Collins, Colorado Cedar Falls, Iowa Steep grades and runaway trucks have the potential of severe and fatal crashes. The use of an emergency escape ramp (EER) accommodates the control of runaway trucks by slowing and stopping them. Fuel or hazardous material (hazmat) spills may result from rollover or jack knife after trucks enter the EER. The objective of this research is to understand the clean-up processes and the remediation techniques after trucks enter ramps, and the auditing/verification processes after the clean-up. Additionally, this study presents a set of recommendations to improve spill clean-up processes and remediation techniques after trucks enter EERs. The recommendations are developed by using the combined method of literature review, phone interviews with staff from western state Departments of Transportations (DOTs), emergency responder companies, and hazmat personnel from Colorado DOT unit as well as exploratory analysis. The implementation of the recommendations will benefit DOTs and freight carriers through improved driver safety and freight security, and the general public through less hazmat discharge into the natural environment. Key Words: Emergency escape ramp, Truck escape ramp, Runaway truck ramp, Fuel spills, Clean- up, Maintenance. Introduction Emergency Escape Ramps (EERs) have proven to be an effective method to control and stop runaway vehicles by transferring the vehicles’ energy through gravitational deceleration, rolling resistance or both (Abdelwahab, & Morral, 1997). -

BMP Chapter 3: Bicycle Network Recommendations
Chapter 3 Bellingham Bicycle Master Plan | Chapter 3: Bicycle Network Recommendations Chapter 3: Bicycle Network Recommendations Chapter 3 presents the recommended network of on-street bicycle facilities that will help Bellingham meet the goals of this Plan. It describes the methodology used to develop the proposed network and suggests facility types for each street segment in the network. This chapter also provides a prioritized list of recommendations to facilitate strategic and timely implementation of the Plan. Network Opportunities and Constraints The City of Bellingham street system presents both opportunities and constraints for developing an on- street, city-wide bicycle network that safely connects all major destinations for bicyclists of all skill levels. In areas of the City that have a traditional street grid pattern, such as Downtown, Fairhaven, and neighborhoods west of Interstate 5 (I-5), there are strong opportunities on local and arterial streets to develop a system of well-connected bicycle facilities. In newer sections of the City, particularly to the east and north of I-5, there are more dead-end streets and larger blocks, making it harder to develop an extensive network of bicycle facilities in these areas. Many of these areas with limited connectivity were built under the current land use and local, State, and federal environmental regulations, which are much more restrictive than in the past and can make street and trail construction - and associated environmental impact mitigation - very expensive. One of the most significant challenges for creating a connected bicycle network is I-5. There are currently eleven arterial streets that cross I-5 over a nine-mile stretch and many of these are intimidating to novice and intermediate bicyclists. -

Page 1 of 32 Draft: Friday, December 8, 2017 www.daytonregionalstemcenter.org Section I: STEM Unit Overview Unit Overview Students are engaged to consider the challenges faced by people in wheelchairs and develop remedial strategies following engineering design. While modern building designs follow specific regulations to provide safe accessibility to wheelchairs, many older neighborhoods still contain designs inaccessible and dangerous for people in wheelchairs. For example, many ramp designs have slopes too large or lengths too short to safely stop a rolling wheelchair. Therefore, students are challenged to design accessible ramps using common rocks and minerals to modify ramp surfaces that can safely and efficiently stop wheelchairs. In completing the design challenge, students will demonstrate understanding of mathematical relationships between speed and motion and differentiation of potential and kinetic energy. By maintaining an Engineering Log, students will also develop skills in writing quantitative ideas and evidence-based argument. -
