Data Science Community

We continue to engage with developers to help us in making driving in London better, with innovative solutions to traffic, road disruption and planned works information through apps created from our open data. As part of our engagement with the developer community we held an Urban Traffic Data Hackathon on 14-15 November.

Supported by our Roads Space Management team, the event was planned in order to give us the opportunity to engage directly with developers to work on creative and innovative solutions to the challenges on London’s roads. In putting the Hackathon together, we worked with Data Science London (DSL), the largest data science community in Europe, and arranged for data scientists and innovators who are members of DSL to take part in the event.

The run up to the event included a pre briefing session with 380 attendees to share our aims and information about the data sets we were making available. The data sets were received with great interest by the group, and the numbers wishing to attend the weekend were so high they had to be limited to the venue capacity.

This continues to open up new ways to explore solutions to London’s challenges. If you attended the Hackathon and have any comments or feedback on the event itself, or if you have any other questions or comments on TfL’s open data and unified API in general, we’d love to hear from you – let us know your thoughts in the comments section below.

Road bicycle racing

Road bicycle racing is the cycle sport discipline of road cycling, held on paved roads.

They provided a template for other races around the world.[citation needed] Cycling has been part of the Summer Olympic Games since the modern sequence started in Athens in 1896.[2] Historically, the most competitive and devoted countries since the beginning of 20th century were Belgium, France and Italy, then road cycling spread in Colombia, Denmark, Germany, Luxembourg, the Netherlands, Portugal, Spain and Switzerland after World War II.

Unlike individual time trials where competitors are not permitted to 'draft' (ride in the slipstream) behind each other, in team time trials, riders in each team employ this as their main tactic, each member taking a turn at the front while teammates 'sit in' behind.

Race distances vary from a few km (typically a prologue, an individual time trial of usually less than 5 miles (8.0 km) before a stage race, used to determine which rider wears the leader's jersey on the first stage) to between approximately 20 miles (32 km) and 60 miles (97 km).

The professional road bicycle racing calendar includes three Grand Tours - the Giro d'Italia, the Tour de France, and the Vuelta a Espana.[3] Ultra-distance cycling races are very long single stage events where the race clock continuously runs from start to finish.

Riding in the main field, or peloton, can save as much as 40% of the energy employed in forward motion when compared to riding alone.[4] Some teams designate a leader, whom the rest of the team is charged with keeping out of the wind and in good position until a critical section of the race.

riders can cooperate and draft each other to ride at high speed (a paceline or echelon), or one rider can sit on a competitor's wheel, forcing him to do a greater share of the work in maintaining the pace and to potentially tire earlier.

Working together smoothly and efficiently, a small group can potentially maintain a higher speed than the peloton, in which the remaining riders may not be as motivated or organized to chase effectively.[5] Usually a rider or group of riders will try to break from the peloton by attacking and riding ahead to reduce the number of contenders for the win.

If the break does not succeed and the body of cyclists comes back together, a sprinter will often win by overpowering competitors in the final stretch.[6] Teamwork between riders, both pre-arranged and ad-hoc, is important in many aspects: in preventing or helping a successful break, and sometimes in delivering a sprinter to the front of the field.[7] To make the course more selective, races often feature difficult sections such as tough climbs, fast descents, and sometimes technical surfaces (such as the cobbled pavé used in the Paris–Roubaix race).

Cyclists have been finding that three- or four-spoked composite front wheels are more stable when confronting crosswinds.[8] Crosswinds, particularly, alter the position of the 'shadow' when drafting a rider, usually placing it diagonally behind the lead rider.[9] To take advantage of this, an attacking rider rides at high speed at the front of the peloton, on the opposite side of the road from which the crosswind is blowing.

If such tactics are maintained for long enough, a weaker rider somewhere in the line will be unable to keep contact with the rider directly ahead, causing the peloton to split up.[10] As well as exceptional fitness, successful riders must develop excellent bike handling skills in order to ride at high speeds in close quarters with other riders.

In professional stage racing, particularly the Tour de France, riders who are not in a position to win the race or assist a teammate, will usually attempt to ride to the finish within a specified percentage of the winner's finishing time, to be permitted to start the next day's stage.

The influence of radios on race tactics is a topic of discussion amongst the cycling community, with some arguing that the introduction of radios in the 1990s has devalued the tactical knowledge of individual riders and has led to less exciting racing.[12] In September 2009, the Union Cycliste Internationale (UCI), the governing body of pro cycling, voted to phase in a ban on the use of team radios in men's elite road racing.[13] However, after protests from teams, the ban introduced in 2011 excluded races on the top-level men's and women's circuits (the UCI World Tour and UCI Women's Road World Cup) and in 2015 the UCI reversed its stance, allowing race radios to be used in class HC and class 1 events from the 2016 season.[14] Within the discipline of road racing, from young age different cyclists have different (relative) strengths and weaknesses.[15] Depending on these, riders tend to prefer different events over particular courses, and perform different tactical roles within a team.

The general leader typically wears a distinctive jersey (yellow in the Tour de France) and generally maintains a position near the head of the main mass of riders (the peloton), surrounded by team members, whose job it is to protect the leader.

Such escapes usually achieve other goals, such as winning the stage, collecting sprinting or mountain points, or just creating air time for their team sponsors as a dedicated camera bike typically accompanies the escape.

The Bicycle Union [of Britain], having quarrelled with the Amateur Athletic Association over cycle race jurisdiction on AAA premises, took issue with the Union Vélocipèdique de France over the French body's willingness to allows its 'amateurs' to compete for prizes of up to 2,000 francs, the equivalent of about sixteen months' pay for a French manual worker.[1] The first international body was the International Cycling Association (ICA), established by an English schoolteacher named Henry Sturmey, the founder of Sturmey-Archer.

In Australia, due to the relatively mild winters and hot summers, the amateur road racing season runs from autumn to spring, through the winter months, while criterium races are held in the mornings or late afternoons during the summer.
